While it may seem tempting to blame the increase in quakes on hydraulic fracturing, or fracking—the much-maligned but increasingly popular method of natural gas extraction—the USGS cautioned against jumping to such conclusions.

Some kinds of quakes are much more likely to cause tsunamis than others; so-called megathrust earthquakes, in which one side of the fault rides up over the other, are especially likely to generate waves.

A series of quakes also ravaged the region in the late 1970s, killing more than 1,500 people in Romania in 1977, dozens in Greece in 1978, and hundreds in 1979 in what was then Yugoslavia.
|
|
The strongest of the quakes were a little less than magnitude 4, meaning they would be felt on the surface perhaps dozens of miles (km) from the epicenter but probably would not do much damage.
|
|
The U.S territory is reeling from two back-to-back 6.4 and 5.9-magnitude quakes that caused large-scale damage in the southern regions of the island — specifically in Guayanilla, Ponce, Yauco and Guánica counties.

Worse than Maria, some say Residents and officials have repeatedly said the impact from the quakes surpasses the devastation that Hurricane Maria, a Category 2003 storm when it hit the island, delivered two years ago.

Seismologists say that shallow quakes were occurring along three faults in Puerto Rico's southwest region: Lajas Valley, Montalva Point and the Guayanilla Canyon, as the North American plate and the Caribbean plate squeeze Puerto Rico.

Titti Postiglione, head of the department's emergency office, said more snow could fall from peaks in the Gran Sasso mountain range in the central Abruzzo region because the temperature was rising, while further quakes were possible.
|
|
Scientists from California State University Fullerton and the United States Geological Survey found evidence the older quakes caused part of the coastline south of Long Beach to drop by one-and-a-half to three feet.
|
|
The first thing you'll notice is that most of the quakes occur around the Pacific Ring of Fire, a place where earthquakes and volcanic action are common thanks to the boundaries of the pacific tectonic plate.
|
|
Mexico City, built on the soft foundation of a dried-out lake bed and thus vulnerable to quakes that occur hundreds of kilometres away, now has a system for alerting residents that a quake is coming.
|
|
After all, there have been an increasing number of quakes in Oklahoma, in part due to wastewater injected into the ground from oil operations (there were two small earthquakes in Oklahoma last night, by the way).
|

Earthquake fast facts Wednesday's seismic event doesn't come close to that, though it is appreciably stronger than the smattering of other quakes from the last few days, as reported by the Southern California Earthquake Data Center.
|
|
The National Disaster Mitigation Agency estimated a series of earlier quakes that hit the resort island of Lombok in July and August had caused damages worth 12 trillion rupiah ($790 million) and killed nearly 500 people.
|
|
Other studies have found no significant evidence for induced quakes in the Los Angeles region after 1935, which Hough said might be explained by the advent of water re-injection and other advances in oil production.
|
|
A third, 22019 magnitude earthquake hit the sea west of Batanes, another province in the Philippines, later Saturday, according to the AP. Photos and videos posted to Twitter show houses and buildings devastated by the quakes.
|
|
On average, big quakes happen on segments of the San Andreas statewide roughly every 150 years, but parts of the fault system in the south near L.A. have not had a rupture for over 300 years.
|
|
A week after the last of the Edmond quakes, Governor Fallin allotted $1.4 million in state funds to the state geological survey and to the Corporation Commission, both of which had been chronically short of money.

Many of the quakes that InSight detected were small enough that they probably wouldn't be felt if they happened on Earth, Philippe Lognonné, principal investigator for one of the lander's instruments, said in a press conference.
|

" When asked what concerns him most about the quakes' aftermath, Escalera said, "That homes will not be safe to live in and the possibility of a collapse that will cause a person's death or serious injuries.
|

The Topix subindex for insurance shares ended 4.4 percent higher after clawing back much of the 5.8 percent it shed on Monday, as property and casualty insurers shares' plunged in the wake of Kyushu's devastating quakes.
|
|
In the hours after the quakes, thousands of residents converged outside the main government building in Rong County to protest widespread fracking in the rolling hills and valleys here now yellowing with the flowering of rapeseed.
|

"Other than the fact that everybody including myself felt more activity, more shaking, more movement than any of the other quakes, amazingly, nobody was injured," said Johnson Bridgwater, director of the Oklahoma chapter of the Sierra Club.
|

Buildings, including homes, need to be constructed so they can better withstand tremors, with construction adapted to various soil types, particularly in the capital whose soft lake-bed foundation can amplify the impact of quakes, said Suárez.

Quakes can make the Earth hum with vibrations when two giant slabs of the crust suddenly slide past each other — "the same as a clapper hitting a church bell," the University of California, Berkeley's Seismo Blog explains.

The uptick in quakes has prompted serious concern among those near the oil storage hub at Cushing, Oklahoma, home to some 66 million barrels of oil and the delivery point for the West Texas Intermediate futures contract.

Gas production company NAM, a joint venture between oil majors Royal Dutch Shell and Exxon Mobil, has accepted responsibility for damage caused by the quakes, for which it is paying more than 1 billion euros ($1.14 billion).
|

The rash of quakes that are happening in the US midwest are likely the result of disposing oil and gas field wastewater deep underground, which is not related to fracking (a common mistake made by the media).
|
|
The researchers started by applying a new algorithm—one that was designed for working with inaccurate data from Earth-based seismic networks with few sensors—in order to re-find the epicenters of the 28 Apollo quakes.
|
|
Template matching can be useful in other seismic hotspots, too, though it relies on a network of seismometers that are closely spaced together—able to match quakes within a one to two mile radius, the study notes.

What's happening in Hawaii now -- a cascade of quakes, an erupting volcano, molten lava covering streets and plumes of vog visible from miles away -- is a simple reminder of exactly how precarious this earthly existence can be.
