The species occurs in damp talus slopes and rockslides of limestone in young forests dominated by Pinus densiflora and Quercus mongolica, mostly under small stones. Although the species is considered locally common, and reasonably widespread (as of 2006, it was known from more than 20 sites), it has not been well studied in the field. Thus, its natural history, population dynamics, and reproductive behavior remain unknown.

The refining zone has vertical limestone cliffs carved by the erosion of the rivers Tarn, Doubie, and Jonte. Over the centuries, some rockslides have created caves ventilated by fleurines, cracks in the rock allowing the circulation of air. It is the biggest of these caves that ripening cellars were built. They have a very stable humidity and temperature, favorable to the development of blue mold.

This would have happened soon after the coins were minted. But the wreck, itself, was never located. Apparently some underwater geological disturbances or rockslides happened in this area since the 3rd century. There's some evidence that the most expensive piece of the hoard — a large golden statue of a youth — has been found but, tragically, later it was melted down by the illegal excavators for its gold value.

It may also occur at very high speed, such as in rockslides or landslides, with disastrous consequences, both immediate and delayed, e.g., resulting from the formation of landslide dams. Factors that change the potential of mass wasting include: change in slope angle, weakening of material by weathering, increased water content; changes in vegetation cover, and overloading. Volcano flanks can become over-steep resulting in instability and mass wasting.

The popular tradition says that the maximum intensity of the earthquake was reached when Prince Constantin Mavrocordat kissed the icon of St. Paraskeva during his visit at a monastery in Moldavia. The earthquake was felt especially in Bucharest, Iași, Focșani, Buzău and Sfântu Gheorghe. In Iași, 11 monasteries, 15 houses, 15 towers and a church steeple collapsed. In the Carpathians, several rockslides occurred, a large one in the Buzău River Valley.

The focus occurred at a depth of approximately 15.5 mi (25 km). Ocean floor shifts created large tsunamis (up to 220 feet (67 m) in height), which resulted in many of the deaths and much of the property damage.Historic Earthquakes: Prince William Sound, Alaska Large rockslides were also caused, resulting in great property damage. Vertical displacement of up to 38 feet (11.5 m) occurred, affecting an area of within Alaska.

Further, a period of rapid cooling occurred just one day before the April slide. However, it is unknown if this series of events combined to act as an exceptional trigger, or if they were rather part of the normal seasonal climatic and hydraulic cycles (Sartori et al., 2003). The large debris fan deposited by the 1991 rockslides can be seen above the village of Randa in the Matter valley.

The Swiss army had deployed a floating bridge in anticipation of the flooding, which successfully allowed the road upstream of the deposit to remain open.

A portion of the Kamehameha Highway was also closed after being submerged under waters of up to deep.

Some galleries have been repaired and partially closed with concrete due to damage from rockslides. The interior of the tunnel is rock- faced, with concrete reinforcement at selected locations. Work on the tunnel was started in 1927 by the Nevada Construction Company and was completed in 1930 at a cost of $503,000 (equivalent to $ million in ). At the time of its completion it was the longest non-urban road tunnel in the United States.

In Grenada, Earl produced heavy rains and strong winds that caused moderate damage. On the main island, roofs were blown off twelve homes while three others were partially damaged; twelve trees and six power poles were also knocked down by the winds. The heavy rain associated with the tropical storm triggered nine mudslides and three rockslides on the island. Nearby, six homes had their roofs completely blown off while thirteen others were damaged.

Rainfall in the days prior to Lenny's approach left areas susceptible to flooding, which caused many rivers in the northeastern portion of the island to overflow their banks following the storm. Such flooding forced towns to evacuate along the rivers, and also resulted in the closure of secondary and primary highways. The heavy rains also caused mudslides and rockslides. The peak rainfall on the island was in Jayuya in central Puerto Rico.

Smart Communications experienced partial loss of its services in Aurora, while Globe Telecom experienced significant loss of service across Southern Luzon. Water supplies were disrupted in Tagkawayan, Quezon, as well as parts of Pamplona, Camarines Sur.

The Gemmi Fault is located within the area and has an earthquake that took place 8,700±2,000 years ago; however earthquakes in Switzerland often are not bound to specific fault systems. Climatic triggers of clustered rockslides are possible but speculative. The movement direction of the Gemmi Fault is congruent with the regional tectonic stress field, which is supported by the kinematics of regional earthquakes which form a cluster that lies south of the fault.

Approximately 6,900 customers lost power near the epicenter: 6,000 in Ridgecrest and 900 in Searles Valley. A wide crack occurred along State Route 178 near Searles Valley and debris covered part of U.S. Route 395. In Trona, several buildings sustained damage, water and gas lines broke, and power lines fell. Rockslides covered multiple roads around the community, blocking off mountain roads, including the section of State Route 178 that connects Bakersfield with Lake Isabella.

This is a mountain with very steep cliffs of loose rocks such as sandstone, and higher up there are cliffs of limestone. During the earthquake there was significant damage done to these cliffs of the Skollis Mountain. This damage resulted in rockslides and landslides. There is account of limestone rock falling from this mountain, which struck a house in the village of Santomeri and caused serious structural damage, but there were no casualties in this incident.

They are also required to pay a tax to bring goods into Canada. After the price for the tax is given, if the player does not have enough, the Mountie will simply take whatever money they have. Along the trail, numerous random events can occur. Random events include: someone being injured (the player decides to continue at a slower pace or to rest), theft of food, rockslides, crowds of people or abandoned animals, and sudden inclement weather.

Starting in June 2006, the Oregon Department of Transportation, using about $1.5 million in state and federal money, began restoring the tunnel to its 1920s appearance. The tunnel official reopened March 21, 2009 for pedestrian and bicycle traffic. The Eagle Creek Fire swept through the Gorge in September 2017, causing rockslides that closed the historic highway for a year. The highway remained closed between Bridal Veil and Ainsworth State Park until November 23, 2018 for restoration and reconstruction work.

The total volume released in this second phase was estimated to be 7 million cubic meters. No one trigger can be conclusively assigned as responsible for the Randa rockslides of 1991. The area has experienced a long history of moderate seismicity, but no significant earthquakes immediately preceded the failures. A warm period producing ample snow melt occurred in the days prior to the April rockslide, and water could be seen emanating from springs on the rock face.

There are several short sections where past rockslides have forced the road to narrow to one lane. Access is controlled via traffic lights. The remaining log cabins and other structures of the ghost town of Independence, also listed on the National Register, are visible in the valley below at east of Aspen. alt=A road curving gently across a grassy landscape with a parking area along it in the center, seen from a slope above it.

An approaching upper-level trough caused Henriette to turn northwest later that day, moving it ashore near San Jose del Cabo, Mexico at 2100 UTC as a minimal hurricane. After crossing Baja California Sur, Henriette weakened to a tropical storm and made a second landfall near Guaymas, Mexico. The system moved inland and quickly weakened, dissipating by 1200 UTC on September 6. The hardest hit city by Henriette was Acapulco, where heavy rains led to rockslides and mudslides that killed six.

In many areas, regular avalanche tracks can be identified and precautions can be taken to minimise damage, such as the prevention of development in these areas. To mitigate the effect of avalanches the construction of artificial barriers can be very effective in reducing avalanche damage. There are several types: One kind of barrier (snow net) uses a net strung between poles that are anchored by guy wires in addition to their foundations. These barriers are similar to those used for rockslides.

About ten miles later, I-40 reaches Crossville, and has three interchanges, including one with US 127, which also conbects to Jamestown. East of Crossville, the Crab Orchard Mountains, the southern fringe of the Cumberland Mountains, come into view as the road descends several hundred feet. At mile 329, the interstate enters Crab Orchard Gap and proceeds through a narrow valley once prone to rockslides. About later, I-40 has an interchange with US 70 near the town of Crab Orchard.

Previously, a road along Asahi Dam was accessible from Route 361, but rockslides and other dangerous bottlenecks along the road led to the creation of the Akigami Bypass along Akigami Dam, which can be used to access Takane, the town of Kisofukushima, the Nomugi Pass and Matsumoto City. However, Asahi Dam itself is not accessible from the bypass that straddles the reservoir. Several other dams are located around Asahi Dam, including Akigami Dam, Takane Dam#1, Takane Dam#2, and Kuguno Dam.

Damage to chimneys, walls, roofs, windows was reported in Richfield, Beaver, Joseph, Elsinore, and Marysvale, with minor damage reported in Parowan, Milford, Cedar City, St. George, and Kanab. Surface ruptures up to in length were reported in Richfield, with water and white sand being ejected from some of the cracks. "Extensive rockslides" were reported between Beaver and Marysvale, especially in the canyons. Damage in Beaver included Beaver Woolen Mills, with an estimated US$4,000 in severe structural damage (approximately US$121,000 in 2020).

The term landslide refers to a variety of mass wasting events (geologic slope failures) that include slumps, slides, falls, and flows. The two major types of slides are rotational slides and translational slides. Rockslides are a type of translational event since the rock mass moves along a roughly planar surface with little rotation or backward tilting. Rock slides are the most dangerous form of mass-wasting because they incorporate a sudden, incredibly fast-paced release of bedrock along a uniform plane of weakness.

Severe weather warnings were issued on Thursday July 7 that were similar in scope to the days before. This time however, the storm affected the Upper Austrian area more, where especially extensive damage had been done by hail in agricultural areas in Gmunden, Vöcklabruck, and Wels. In Dürnstein in Wachau, there were rockslides at Vogelbergsteig, which blocked both the Danube Highway and the Danube Railway. The B3 became once again freely passable on July 10 after explosions that removed loose rock from the wall.

The Magdalena alpine (Erebia magdalena) is a member of the subfamily Satyrinae of the family Nymphalidae. It is found in North America from Montana, Colorado, Utah, and New Mexico, and in Canada in a small part of the Willmore Wilderness Park, Alberta, and adjacent British Columbia, in Stone Mountain Provincial Park in northern British Columbia, and on an isolated nunatak in Kluane National Park and Reserve, Yukon. The habitat consists of rockslides near vegetation, at or above the treeline. The wingspan is 41–45 mm.

In Saint Croix, a roadway section leading into Enfield Green collapsed, temporarily cutting the neighborhood off to traffic until a makeshift roadway was created the next day. In La Vallée, on the island's north shore, floods and landslides affected low-lying areas. Traffic on Saint Thomas and Saint John initially remained unhindered; however, as the rain continued for several days, flooding, rockslides and asphalt erosion forced authorities to close several roads and highways. Damage estimates from the storm reached $2 million across the islands.

Henriette as a strong tropical storm to the west of Jalisco Henriette struck hardest in the resort town of Acapulco. Though the storm never passed closer than to the town, heavy rains along the coast saturated the ground, leading to mudslides. Six people were reported dead as a result of rockslides in two suburban neighborhoods of the city and in the port itself. Three were killed by a huge rock hitting their house, and the other three were killed when their dwellings partially collapsed.

The alternative is to walk 10 km up the access road carrying all their equipment. From Lake O'Hara, people going to the hut can follow the signed hiking trails to Lake Oesa to a sign marking the end of the Parks Canada trail, at which point it becomes largely scrambling. A trail has been built to the hut by the Alpine Club, but parts of it are sometimes erased by rockslides, so route finding skills are helpful. It is steep and covered with scree.

This entire section is considered very scenic and is prone to rockslides in many locations. Around milepost 130, about from Rocky Top, I-75 begins its first major ascent for a few miles before leveling out, and at exit 134, near the community of Caryville, US 25W splits off and I-75 begins a concurrency with SR 63. The Interstate then begins another ascent, this one steeper, adding a truck climbing lane going northbound. About later, the highway levels out once again and the truck lane terminates.

Pennsylvania Route 271 (PA 271) is a north–south state route located in Western Pennsylvania. Its southern terminus is at PA 711 in Oak Grove in Ligonier Township, and its northern terminus is at U.S. Route 219 (US 219) in Northern Cambria. The route was designated on May 27, 1935 in coordination with the release of a new state road map. The easy grade section of the highway in Johnstown is notorious for the many rockslides that occur on the hillside above the road.

Foot access to the canyon is available at four rest areas along Interstate 70 in the canyon. The Hanging Lake Rest Area (exit 125) provides access to the canyon along a stretch where I-70 is concealed in the Hanging Lake Tunnel. The freeway is also prone to rockslides in the canyon, such as the one that closed it in February 2016. The canyon was formed relatively recently in Pleistocene time by the rapid cutting of the Colorado down through layers of sedimentary rock.

The snail lives on rocky mountain slopes, taking shelter in talus and rockslides. During the dry conditions common in its habitat, the snail seals its shell aperture to solid rock to avoid desiccation. The rock should be rich in calcium carbonate, which the snail uses to form its shell. It is associated with local plant species such as saguaro cactus (Carnegiea gigantea), yellow paloverde (Parkinsonia microphylla), brittlebush (Encelia farinosa), foxtail brome (Bromus madritensis), Natal grass (Melinis repens), creosote bush (Larrea tridentata), and Coulter's lupine (Lupinus sparsiflorus).

In the past, supplies had to be shipped to Rooi-Els and walked up the pass by drovers. Businessman Gerald "Jack" Clarence, who owned property in Hangklip and Betty's Bay, proposed building a road through the area, which would begin construction in 1940 and would be completed by Italian POWs during World War II. On May 29, 1998, Premier of the Western Cape Gerald Morkel opened reconstructed portions of the road. Overlooks have been built, but there are still some sharp turns and rockslides sometimes occur.

Fear of rockslides from Chaos Crags prompted the closure of the Visitor Center at nearby Manzanita Lake Additional volcano hazards at Lassen are rockfalls and landslides not directly related to eruptions. Recently erupted volcanic domes are unstable and can collapse, generating small to large rockfalls. Approximately 350 years ago, collapse of one of the Chaos Crags domes generated huge rockfalls, creating an area now called the Chaos Jumbles. The first and largest of these traveled downslope and was able to climb up the side of Table Mountain.

Mass-wasting occurs whenever gravitational pressure exceeds the affected slopes ability to resist its pressure. Therefore, anything that erodes or impedes the mountain's ability to resist this force may be one of the causes of mass-wasting. While a major event such as an earthquake can cause large rockslides to happen, a majority of slides occur due to a combination of gravitational pressure and erosional influences. Amongst these erosional properties, water is arguably the most effective geologic agent that causes mass-wasting events to occur.

A Western Pacific passenger train in the grand canyon, circa 1910s Construction of the line began in 1906 and continued under harsh conditions. In the Sierra a total absence of roads, along with rockslides in the Feather River Canyon and extreme temperature fluctuation, made working conditions uncomfortable and dangerous. In the deserts of Nevada and Utah high temperature and lack of water made conditions similarly difficult; construction costs skyrocketed, nearly bankrupting the contractors building the line. Labor turnover was extremely high, due to the miserable working conditions.

These guesthouses are not well heated, which combined with the unpredictable nature of high mountain weather makes this trek unadvisable during the rainy season. The lower road, stretching about from Qiaotou through the Gorge, is a stretch of pavement (until recently a simple mule track) crossed by several waterfalls, and frequently beset by rockslides. Some portions of the road have been known to disappear into the river below. The road follows the Yangtze, so there are more views of the river, and a stronger sense of being in a gorge than on the upper trail.

There are two small populations in the Waianae Range of Oahu, three on Molokai, ten on Kauai, and one on Keopuka Rock, an islet close to the coast of Maui.USFWS. ETWP; Determination of endangered or threatened status for 24 plants from the island of Kauai, HI. Federal Register February 25, 1994. There are fewer than 10,000 individuals, and perhaps fewer than 5,000. Threats to the species include non-native plants such as lantana (Lantana camara), as well as feral goats, hiking and the maintenance of hiking trails, fires, landslides and rockslides.

Several volcanic eruptions have been studied in North America. On 18 May 1980, Mt. Saint Helens, a stratovolcano, in Washington state erupted spreading five hundred million tons of tephra ash across Washington, Montana and Idaho causing earthquakes, rockslides, and megatsunami which severely altered the topography of nearby areas. The effects of the Mt. Saint Helens eruption was felt as far away as Yellowstone National Park, where eruption related flooding caused trees to collapse and wash into lake beds where they fossilized. Nearby forests were flooded, removing bark, leaves, and tree limbs.

Unstable geology is prevalent throughout the canyon, and occasional rockslides have formed impounded lakes in the canyon, the most recent of which was roughly 4,000 years ago. Owing to the extreme depth of the canyon, there are many springs fed by the surrounding groundwater, permitting water in the canyon to run year round. Mormons migrated from the lower Virgin River area in the late 1850s. The canyon was named by settler Isaac Behunin, who named the canyon after a "place of peace" mentioned in 2 Samuel 5:7 of the Bible.

This section is extremely curvy and the speed limit reduces to 55 mph due to its susceptibility to accidents. This stretch is also prone to rockslides, and contains mesh nets along some of the cliff slopes as preventative measures. A few miles later I-40 crosses the Pigeon River and has an interchange with the Foothills Parkway, before crossing the Pigeon River again about later and curving sharply to the east. A bout later, the route curves to the south again near the unincorporated community of Hartford before entering North Carolina about later.

On 7 March, Prime Minister John Key said that around 10,000 houses would need to be demolished, and liquefaction damage meant that some parts of Christchurch could not be rebuilt on. ;Residential red zone Several areas in and around Christchurch were deemed infeasible to rebuild due to earthquake damage resulting from soil liquefaction and rockslides. These areas were placed into a residential red zone. ;Lyttelton Buildings in Lyttelton sustained widespread damage, with a fire officer reporting that 60% of the buildings in the main street had been severely damaged.

Several large mudslides and rockslides on May 19-20, 2005 damaged or destroyed the Montana side of the Beartooth Highway in a dozen places between mile markers 39 and 51. The road was closed for reconstruction, and a $20.4 million construction contract issued which stipulated an October 2005 completion date. Construction was completed ahead of schedule however the highway did not reopen for a year. An estimated of rock was removed from a section of the highway near the top of the switchbacks, and construction crews drilled down to solid bedrock to create new supports for the road.

In 2002 and 2003, two state troopers were killed in two separate accidents by speeding trucks that drifted off the road and hit their police car conducting a traffic stop. This led the North Carolina Highway Patrol to crack down on speeding tractor trailers and speeders in general through the area. This portion of the highway is also notorious for rockslides and rocks falling onto the highway. The main cause is an engineering flaw, in that sections of the highway have been built on the north side of the Pigeon River, where the rock strata foliate towards the highway.

Enchanted Pond is a mountain pond in the U.S. state of Maine. Situated in the Western Maine Mountains in the Northwest Somerset Region, the pond is located in a deep mountain valley between Coburn Mountain (to the east) and Shutdown Mountain (to the west). Near its southern end, the pond is distinguished by two rockslides from the exposed cliffs of these mountains that extend down into the water along both shores. Enchanted Pond is fed by mountain springs and Little Enchanted Pond, and is the primary source of Enchanted Stream which flows into the Dead River, a tributary of the Kennebec River.

There are escape ramps branching off both sides of the downward part of the road for heavy trucks whose brakes fail on this five mile long, 6% grade, 1600-foot ascent - and now straight - grade. The Grapevine is subject to severe weather and closure to traffic in winter. The stretch of I-5 through the Grapevine and the Tejon Pass is sometimes closed by the California Highway Patrol, generally because of the icy conditions combined with the steep grade of the pass, and the high volume of traffic during the winter holidays. Occasionally, heavy rains will cause mud and rockslides, closing the freeway.

Grand Canyon National Park categorizes the Hermit Trail as a threshold trail and does not officially maintain it. The trail is rutted in many places, and the once exquisite construction of placed stones on the upper half of the trail is now crumbling and rough. Numerous rockslides cut through the trail and require rock scrambling and route finding to pass. The most recent major rockslide occurred in the evening of 1 March 1983, when a large section of rock in the Supai Group broke away from a cliff face and scattered down Hermit Canyon, cutting the Hermit Trail in two places.

Because of rain, mudslides, falling trees, soil erosion and rockslides, the regularly monitored trail course changes almost every year, and no official records of running times are kept. The course starts and ends on pavement, but most of the race is run on a dirt path about three feet wide, and the Mt. Wilson Trail has occasional steep vertical drops of hundreds of feet. Due to the trail's narrowness and steepness, the race is limited to 300 male and 300 female runners. The path gains elevation to more than ; at from the start of the race is Orchard Camp, the turnaround point.

Indeed, whether or not the myth of the village's founding is true, the location of Balla/Pefko saved it from Turkish occupation. The orientation of the village was very strategic, as it is hidden between two rises making it very hard for the Turks and other occupiers to find. Balla/Pefko was a major center of guerrilla resistance activities against both the Turks and the Germans, the latter who found the village and burned it due to the villager's activities in resisting the Nazi occupation. The village was also partially destroyed in the 1970s due to rockslides, but later rebuilt.

These lines are lower in Scandinavia and higher in southern Europe Because of the harsh weather conditions that prevail at those higher altitudes, maintaining working railways there is an expensive and difficult task. Snow, avalanches, rockslides and wind, added to the absence of protection by the forests, pose a challenge in every season. Lower elevation railways (even well below the tree line) are also exposed to more severe weather conditions in winter. Many of the high-elevation railway lines rely on heavy protection infrastructure with some of them built partially underground, notably the Jungfrau and Zugspitze railways.

The extent of tephra deposits would depend on wind strength and directions. However, given the sudden nature of rockfall-avalanches, these would be more dangerous than pyroclastic flows or tephra, as they could occur without warning, seriously endangering life within of the Crags. The Chaos Crags are monitored for movement in case of future rockslides by the United States Geological Survey; GPS receivers have been in place to monitor deformation within the Lassen volcanic center since 2008. 13 seismometers in the vicinity, first installed in 1976 and since updated each decade, continually survey earthquakes within the locale.

Not all the buildings in San Jacinto were completely destroyed by the thirty seconds of shaking, but most of the brick buildings' second floors were heavily damaged. () ShakeMap showing the intensity of the 1968 Borrego Mountain earthquake ; 1968 Borrego Mountain earthquake On April 9, a magnitude 6.4 ML earthquake with a maximum perceived intensity of MM VII hit the extreme eastern San Diego County area and created a surface break along the Coyote Creek Fault. California State Route 78 was damaged with cracks near Ocotillo Wells and large boulders blocked the Montezuma-Borrego Springs Highway. Other rockslides occurred at Palm Canyon and Split Mountain in Anza-Borrego Desert State Park.

This 7th winter sees some of the younger generation stepping up, as Cary Quiring is one of the first to respond to a mass-casualty event on the Coquihalla and Dylan Greenwood of Mission Towing takes the lead on some big wrecks and recoveries in the Fraser Valley. Reliable Towing out of Merritt, British Columbia makes their debut in the second half of Season 7, first on a small truck and trailer wreck with pigs inside and then in the next episode with a 6 semi crash on the Coquihalla north of Merritt. Mudslides and rockslides contribute to a tough time for recovery crews all around.

The more gently sloping lower part of the volcano is also known as Ubinas I and the steeper upper part as Ubinas II. The southern flank is cut by a noticeable notch, which is probably not an eruption vent and may have been formed by mudflows and rockslides. Due to weathering, the upper sector of the volcano has a worn appearance. Glacial valleys such as the Ubinas and Para valleys, as well as cirques and moraines down to and at the foot of the volcano, indicate that glaciers developed on Ubinas during the last glacial maximum. Other volcanic cones in the region all show heavy erosion by glaciation.

The valley floor lies at elevations between 1400 m above NN at the source of the Partnach river, 1,002 m at the entrance to the gorge of the Hinteren Klamm and 797 m at the start of the Partnachklamm gorge, in the upper Reintal therefore about 1300 to 850 m above the surrounding mountain peaks. [?] In the upper Reintal the rubble from rockslides from the southern faces of the Hochwanner and Hinterreintalschrofen also play a rôle in the shaping of the valley. These have spilled into the old glacial valley, forced back the course of the Partnach to the north and, in places, impounding it.

In December 1986, a truck driver was killed when his truck skidded across some rocks that had spilled across the road just east of Crab Orchard between miles 331 and 333. In response, the Tennessee Department of Transportation (TDOT) flattened the cutslopes along this stretch of Interstate and moved the road away from the problematic cliffside. Twenty rockslides occurred along the Walden Ridge section, miles 341–346, of the eastern plateau in 1968 alone, prompting various remedial measures throughout the 1970s, including the employment of rock buttresses, gabion walls, and horizontal drains. A minor rockslide shut down the right lane of westbound I-40 at mile 343 on May 6, 2013.

RNZAF aerial survey of damage, showing flooding due to soil liquefaction in Christchurch; most of the land in the image was later red- zoned and all structures demolished Avondale, part of which was later placed in the red zone (note the bump in the road where soil liquefaction pushed up an underground storm drain) In the 2010 and 2011 earthquakes, many areas in and around Christchurch were severely affected by soil liquefaction, lateral spreading, and/or rockslides. Many flatland areas were flooded and covered in silt as a result of liquefaction, and houses and utilities were damaged. Such areas were rendered effectively uninhabitable by the quakes.

In Summer a gondola lift runs from Sellajoch up to the col of Langkofelscharte and the Toni Demetz refuge hut. From there both the Langkofel (via the Langkofel Hut, Confinböden and the Emilio Comici Hut), as well as the Plattkofel (via the Langkofel Hut, Plattkofel Hut and Frederick Augustus Way) may be circled on hiking trails. The Plattkofel may be reached from the Langkofelkar on the klettersteig route known as the Oskar Schuster Steig and from the Plattkofel Hut over the steep western flank (here without climbing). Between the Langkofel and the Sellajoch is the area of rockslides known as the "Rocky Town" (Steinernen Stadt), notable especially for its rich flora.

Its epicenter was in the municipality of Rizal, Nueva Ecija, about northeast of Pinatubo, and faulted northwest-southeast through three provinces. It also followed the Philippine Fault System west as far as Baguio, which was devastated, and is located about north-northeast of Pinatubo, leading volcanologists to speculate that it might ultimately have triggered the 1991 eruption, although this is impossible to prove conclusively. Two weeks after the earthquake, local residents reported steam coming from the volcano, but scientists who visited there in response found only small rockslides rather than any pre-eruptive activity. On March 15, 1991, a succession of earthquakes were felt by villagers on the northwestern side of the volcano.

The encroachment of residential development from the north forced the Bureau of Land Management and The Nature Conservancy to buy additional properties in the canyon for preservation in the 1990s. Beginning in 1996, the state government embarked on a targeted anti- drunk driving campaign along SR 821, which had been the site of over 115 collisions between 1992 and 1995, of which 25 were alcohol-related. The first year of the campaign was hailed as a success, with two consecutive summer months without a recorded collision and 2,200 police stops for driving violations. Eight separate sections of the highway were closed for several weeks in July 1998 due to rockslides and washouts brought by of rainfall on July 3.

The plant is widespread across of North American in much of the western United States and western Canada, from British Columbia and Montana south to California and New Mexico, with a few populations in the Black Hills of South Dakota and in western Nebraska,Biota of North America Program 2014 county distribution map as well as in South America in the Andean valleys of Chile and Argentina. C. viscidiflorus grows easily in alkaline and saline soils, and thrives on soils that are rich in calcium.Forest Service Fire Ecology It rapidly establishes in disturbed habitat, including burns, flooded washes, and rockslides, so it is a valuable shrub for revegetating damaged land such as overgrazed rangeland and abandoned mining areas.

It has been active in post- glacial time. Luminescence dating has yielded ages of 8,700±2,000 and 2,400±500 years, which have been interpreted as either two earthquakes or as an upper limit to the age of the last fault movement. This implies that the Gemmi Fault was active during the Holocene. Earthquakes frequently cause multiple rock slides during each event, and a number of such rockslides are documented from Switzerland. Rock slides in the Kander valley and at Rinderhorn appear to be contemporaneous about 9,800-9,600 years ago within dating uncertainty, and sediment deposits within Lake Lucerne and Lake Seelisberg indicate that an earthquake with magnitude exceeding 6 took place 9,870-9,960 years ago.

The 1991 rockslides at Randa consisted of two separate collapse events on April 18 and May 9, which released in total a cumulative volume of approximately 30 million cubic meters of rock. The elevation of the top of the scarp is 2320 m (7610 ft), while the elevation of deposit toe is 1320 m (4330 ft). Accelerating occurrences of small rockfalls from the cliff in the decades preceding the slides gave indication of deeper movements, and fallen debris had eventually destroyed much of the forest beneath the cliff (Sartori et al., 2003). Precursory events noted immediately prior to the April, 1991 rockslide included explosive ruptures of rock slabs and new forceful water discharges from the face (Schindler et al.

These uniform weaknesses are key to identifying rock slides because unlike slumps, flows, or falls, the failed material moves in a fairly uniform direction over a layer of solid, pre-existing rock. Rock may break down while falling during rockslides. The sudden, rapid release of material found in rock slides combined with the sheer size and weight of the material that is falling is what gives these events the potential to have devastating effects on human life and infrastructure. Rock slides are very common in the over steepened canyons and drainages of Idaho, particularly in those areas like the Salmon River Canyon where more than 5,000 feet of elevation may exist between the ridge tops and the canyon bottoms.

River outlet works are open during high flow experiment in December 2012. On March 26, 1996, the penstocks and two of the outlet works' bypass tubes at Glen Canyon Dam were opened to maximum capacity, causing a flood of to move down the Colorado River. This was the first of the Glen Canyon Adaptive Management Program "high flow experiments", a controlled effort to assist the recovery of the damaged riverine ecosystem by mimicking the floods that once swept through the canyons each spring. The flow appeared to have scoured clean numerous pockets of encroaching vegetation, carried away rockslides that had become dangerous to boaters, and rearranged sand and gravel bars along the river, and was initially believed to be an environmental success.

The local village of Isola owned the land he wanted to build the resort on – a small town located at an altitude of 900m, with poor prospects for development as citizens were migrating to the cities. As a result of this, the local mayor was happy to allow Boumphrey, and the London-based contractors he persuaded to help him, to build a ski resort above Isola, as the land required was of little value as farmland. The regional government was concerned not too much about the resort itself, but about the road that was required to access it. Before the resort existed there was a small dirt road up the resort's location, and avalanches were constantly blocking this in the winter, as well as rockslides in the summer.

The tasks of a geotechnical engineer comprise the investigation of subsurface conditions and materials; the determination of the relevant physical, mechanical, and chemical properties of these materials; the design of earthworks and retaining structures (including dams, embankments, sanitary landfills, deposits of hazardous waste), tunnels, and structure foundations; the monitoring of site conditions, earthwork, and foundation construction; the evaluation of the stability of natural slopes and man-made soil deposits; the assessment of the risks posed by site conditions; and the prediction, prevention, and mitigation of damage caused by natural hazards (such as avalanches, mud flows, landslides, rockslides, sinkholes, and volcanic eruptions).Terzaghi, K., Peck, R.B. and Mesri, G.

Losses in the category of crops were estimated at NT$201.45 million (US$6.05 million), with 8,018 hectares affected. Heavy rainfall on September 28 and 29 led to serious rockslides at a section of the Alishan Forest Railway which was destroyed by Typhoon Morakot and reconstructed recently, ruining plans by the Taiwan Railways Administration to reopen the full length of the railway on December 25. Bon Jovi's only two concerts at the Taipei World Trade Center Nangang Exhibition Hall on September 28 and 29 were canceled due to Typhoon Dujuan, as the Taipei City government announced school and office closures for the two days. During the first landfall, the weather station in Su'ao, Yilan observed the maximum gust at and maximum sustained winds at , and that gust became the second strongest of the station in history.

Example of how reversed archaeological stratigraphy may form. Reverse stratigraphy (sometimes known as inverted stratigraphy) is the result of a process whereby one sediment is unearthed by human or natural actions and moved elsewhere, whereby the latest material will be deposited on the bottom of the new sediment, and progressively earlier material will be deposited higher and higher in the stratigraphy. Such events can be triggered by rockslides, tree throws, or other events which cause the strata of a deposit to be flipped or reversed. In archeological excavations a common cause of inversions in the stratigraphy is the collapse of walls on river banks or other raised mounds where deposits which have been cut through behind the wall prior to collapse slip over the collapsed structure resulting in the structure being under the deposits that originated earlier in time.

The Colorado through Grand Canyon now lacks the source of sediment it needs to build sandbars and islands, and these natural fluvial formations within the canyon have now suffered severe damage from erosion. The floods that once scoured the river each year are now contained behind the dam except in extraordinary cases such as 1983–84; the lack of floods has promoted vegetation encroachment which not only has considerably changed the riparian zone environment but has created problems for tourism, as hikers and boaters often cannot find good spots to camp due to overgrowth. Flood control has also caused an inability of the river to carry away the rockslides that are common along the canyons, leading to the creation of incrementally dangerous rapids that pose a hazard to fish and boaters alike. Before damming, the Colorado commonly reached flows of more than during the spring; this has been limited to less than most years with few exceptions.

The show was created by Mark A. Miller, Kevin Mills and Neil Thomas. Neil Thomas met one of Jamie Davis' heavy rescue operators after his moving truck broke down on Highway 5 in the summer of 2010. In the early winter of 2011 Cameraman Kevin Mills and executive producer Mark Miller were passing through Hope, BC and dropped in on Jamie Davis Motor Truck. The idea of a show about heavy recovery was discussed; Davis expressed a desire to change the public's perceptions about his industry. The winter of 2010-2011 had been a record setting season for JDMT. The show debuted on Discovery Channel (Canada) on Tuesday September 4, 2012 in Canada. Steep hills, lethal drop-offs, killer rockslides, and the worst weather in a decade captivated audiences, with Highway Thru Hell ranking as the #1 series premiere in Discovery Channel Canada's history. Its second season, premiered on September 3, 2013, and featured 13 episodes as well as four reloaded episodes with new content, factoids and viewer tweets.

Westbound through the Arch Rock Tunnel, the westernmost of the three Construction began on July 1, 1928, with convict labor for the easier portions and contractors for the remainder, as well as bridges and tunnels, but was slowed by the Great Depression. On the most difficult portion, between Cresta and Rock Creek, three tunnels had to be built at Arch Rock, Grizzly Dome, and Elephant Butte; at the former two, surveyors had to hang out on rope over steep granite slopes, and rockslides repeatedly caused delays. The commission dedicated the road at a ceremony at Grizzly Dome, halfway between the ends, on August 14, 1937. Construction had cost $8.15 million for 78 miles (126 km) of new road. The remainder of the old trail from Quincy to the junction with Route 29 (now U.S. 395) east of Beckwourth Pass was added to the state highway system in 1931 as an extension of Route 21,: "Quincy to State Highway Route 29, near Chats." and was paved by 1936. A new Route 87 was created in 1933, stretching from Woodland via Marysville and Oroville to Route 3 (State Route 99) southeast of Chico, including the present SR 70 between Marysville and Oroville.
