The ostraciiform group have no appreciable body wave when they employ caudal locomotion. Only the tail fin itself oscillates (often very rapidly) to create thrust. This group includes Ostraciidae.

A method that avoids making the variational overestimation of HF in the first place is Quantum Monte Carlo (QMC), in its variational, diffusion, and Green's function forms. These methods work with an explicitly correlated wave function and evaluate integrals numerically using a Monte Carlo integration. Such calculations can be very time-consuming. The accuracy of QMC depends strongly on the initial guess of many-body wave-functions and the form of the many-body wave-function.

Designers should consider some important factors, including lateral body motions, kinematic data and anatomical data. When designers mimic a BCF-type robot fish, the link-based body wave of the robot fish must provide motions similar to that of a living fish. This kind of body wave-based swimming control should be discrete and parameterized for a specific swimming gait. Ensuring swimming stability gait can be difficult, and transitioning smoothly between two different gaits can be tricky in robot fish.

Although more rare than deep events, the shallow events were larger, with body wave magnitudes > 5.5 and stress drops exceeding 100 MPa. Other sources of seismic activity included meteorite impacts and artificial signals from lunar modules.

In the framework of many-body quantum mechanics, models solvable by the Bethe ansatz can be contrasted with free fermion models. One can say that the dynamics of a free model is one-body reducible: the many-body wave function for fermions (bosons) is the anti- symmetrized (symmetrized) product of one-body wave functions. Models solvable by the Bethe ansatz are not free: the two-body sector has a non-trivial scattering matrix, which in general depends on the momenta. On the other hand, the dynamics of the models solvable by the Bethe ansatz is two-body reducible: the many-body scattering matrix is a product of two-body scattering matrices.

Its solution for a reasonably large number of particles is therefore typically impossible, even for modern parallel computing technology in a reasonable amount of time. Traditionally, approximations for the many-body wave function as an antisymmetric function of one-body orbitals have been used, in order to have a manageable treatment of the Schrödinger equation. However, this kind of formulation has several drawbacks, either limiting the effect of quantum many-body correlations, as in the case of the Hartree–Fock (HF) approximation, or converging very slowly, as in configuration interaction applications in quantum chemistry. Quantum Monte Carlo is a way to directly study the many-body problem and the many-body wave function beyond these approximations.

The large and damaging tsunami that was generated was out of proportion relative to the size of the event, based on its short-period body wave magnitude. The Indonesian Meteorological, Climatological, and Geophysical Agency assigned a magnitude of 6.8, and the United States Geological Survey (USGS) reported a similar value of 6.1 (both body wave magnitude) that were calculated from short-period seismic waves (1–2 seconds in the case of the USGS). The USGS then presented a moment magnitude of 7.2 that was calculated from 5–100-second surface waves, and Harvard University subsequently revealed that a moment magnitude of 7.7 had been resolved based on even longer 150-second surface waves.

In 1983, Laughlin was first to provide a many body wave function, now known as the Laughlin wavefunction, for the fractional quantum hall effect, which was able to correctly explain the fractionalized charge observed in experiments. This state has since been interpreted as the integer quantum Hall effect of the composite fermion.

On November 19, 2012, Cordova was hit by a minor rock burst that had a body wave magnitude of 2.6. The Mercalli intensity was estimated at II–III (Weak) in Cordova. It was felt throughout Alabama and the Southern United States, up to from the epicenter. By comparison, a magnitude 3.6 event on the West Coast would not be felt from the epicenter.

Surrounding the epicenter were several small towns built on flat glacial lake plains and low hills. (See this bulletin on the webpage of Earthquake Center of Saint Louis University) Scientists described the rupture as "strong". During the quake, surface wave and body wave magnitudes were measured at 5.2 and 5.54, respectively. The magnitude of the quake reached 5.4 on the Richter scale.

1983 Kopaonik earthquake occurred on September 10 at 06:14 UTC with a body wave magnitude of 5.3 and a maximum Mercalli intensity of VIII (Severe). The epicenter was in the Kopaonik mountains of Serbia. It affected seven villages, leaving 200 homeless, and 1,200 buildings and dwellings damaged. Kopaonik was hit five times by earthquakes of intensity VII to VIII between 1978 and 1985.

The earthquake had a magnitude of 5.9 on the moment magnitude scale, making it the largest in the region since 2005. The hypocentral depth is estimated as 8 km from body wave modelling. The calculated focal mechanism indicates reverse faulting with a small component of strike-slip, on two possible fault planes, either dipping 43° to the north or 52° to the southeast.Nissen et al.

There are many other interpretations of quantum mechanics. In 1927, Hartree and Fock made the first step in an attempt to solve the N-body wave function, and developed the self-consistency cycle: an iterative algorithm to approximate the solution. Now it is also known as the Hartree–Fock method. The Slater determinant and permanent (of a matrix) was part of the method, provided by John C. Slater.

The 1989 Gissar earthquake occurred at 23:02 UTC on 22 January near Gissar in Tajikistan. The shock had a body wave magnitude of 5.3 and a maximum felt intensity of VII (Very strong) on the Mercalli intensity scale. The National Geophysical Data Center reported that the death toll from the event amounted to about 274, and the National Earthquake Information Center stated there were many injured. This was the deadliest earthquake in 1989.

Deep-focus earthquakes give rise to minimal surface waves. Their focal depth causes the earthquakes to be less likely to produce seismic wave motion with energy concentrated at the surface. The path of deep-focus earthquake seismic waves from focus to recording station goes through the heterogeneous upper mantle and highly variable crust only once. Therefore, the body waves undergo less attenuation and reverberation than seismic waves from shallow earthquakes, resulting in sharp body wave peaks.

However, the best fit to both the results from body wave modelling and SAR interferometry comes from a model with two contiguous fault segments, one to the northeast with a strike of 025°, and the other to the southwest with a strike of 065°, both with an overall southeasterly dip. It has been suggested that this earthquake and the 2005 Qeshm event may have ruptured adjacent parts of the same fault.Nissen et al. 2010, p. 192.

Atmospheric focusing caused blast damage at even greater distances, breaking windows in Norway and Finland. Despite being detonated above ground, its seismic body wave magnitude was estimated at 5.0–5.25. Immediately after the test, several U.S. Senators condemned the Soviet Union. Prime Minister of Sweden, Tage Erlander saw the blast as the Soviets' answer to a personal appeal to halt nuclear testing that he had sent the Soviet leader in the week prior to the blast.

The ISC- GEM Global Instrumental Earthquake Catalogue (1900-2013) (prepared at the request of the GEM Foundation) catalogs magnitude 5.5 or greater earthquakes suitable for modeling and assessing seismic hazard and risk. Epicentral locations and hypocentral depths were recalculated from original travel time data using a consistent velocity model. Magnitudes are expressed as moment magnitude scale (Mw), taken either from reliable published values of seismic moment or from recalculated values of surface wave or body wave magnitude, converted to Mw using empirical relationships.

Rayleigh waves are much slower than body waves, at roughly 90% of the velocity of for a typical homogeneous elastic medium. Rayleigh waves have energy losses only in two dimensions and are hence more destructive in earthquakes than conventional bulk waves, such as P-waves and S-waves, which lose energy in all three directions. A Love wave is a surface wave having horizontal waves that are shear or transverse to the direction of propagation. They usually travel slightly faster than Rayleigh waves, at about 90% of the body wave velocity, and have the largest amplitude.

The creation and annihilation operators are introduced to add or remove a particle from the many-body system. These operators lie at the core of the second quantization formalism, bridging the gap between the first- and the second-quantized states. Applying the creation (annihilation) operator to a first-quantized many-body wave function will insert (delete) a single-particle state from the wave function in a symmetrized way depending on the particle statistics. On the other hand, all the second-quantized Fock states can be constructed by applying the creation operators to the vacuum state repeatedly.

The Richter and MMS scales measure the energy released by an earthquake; another scale, the Mercalli intensity scale, classifies earthquakes by their effects, from detectable by instruments but not noticeable, to catastrophic. The energy and effects are not necessarily strongly correlated; a shallow earthquake in a populated area with soil of certain types can be far more intense in effects than a much more energetic deep earthquake in an isolated area. Several scales have historically been described as the "Richter scale", especially the local magnitude and the surface wave scale. In addition, the body wave magnitude, , and the moment magnitude, , abbreviated MMS, have been widely used for decades.

From April 1926 onwards, the island of Faial was rocked by a series of tremors that increased in intensity, until 5 April. On this date, a singular event resulted in destruction or damage to buildings in the civil parishes of Flamengos, Ribeirinha and Conceição, in particular in the localitiesof Farrobo, Lomba and Espalhafatos. On 31 August, at about 8:40 in the morning, the islands were raised by a violent earthquake with its epicentre centralized in the Faial-Pico Channel, at a depth of and with a body wave magnitude of 5.3–5.9. The earthquake progressed to a Mercalli Intensity of X (Extreme) in the northern part of Horta (around Conceição).

In computational physics and chemistry, the Hartree–Fock (HF) method is a method of approximation for the determination of the wave function and the energy of a quantum many-body system in a stationary state. The Hartree–Fock method often assumes that the exact N-body wave function of the system can be approximated by a single Slater determinant (in the case where the particles are fermions) or by a single permanent (in the case of bosons) of N spin- orbitals. By invoking the variational method, one can derive a set of N-coupled equations for the N spin orbitals. A solution of these equations yields the Hartree–Fock wave function and energy of the system.

Separating natural earthquakes from mining related seismicity is difficult since most mines are also located in seismically active regions of Canada and the routine blasting at the mines is registered in Canadian seismic catalogues. For example, the Western Canadian Composite Seismicity Catalogue documented 3,898 earthquakes above moment magnitude 2 that were attributed to blasting as of July 2017. Induced seismicity up to body wave magnitude (Mb) 5.0 has been documented at Devonian Potash mines in Saskatchewan and at Cretaceous coal mines in northern Ontario. One such sequence of earthquakes occurred in a potash mine near Saskatoon between 1979 and 1980 and another sequence occurred between 2005 and 2015, culminating in a Mb 4.0 event near Yorkton, Saskatchewan in January 2015.

The Bou'in-Zahra earthquake was located in an area of active thrust faulting and folding, parallel and south of the southern edge of the Alborz mountain range, and was the 11th rupture in the previous two months in central Iran. A seismic inversion of long-period P and SH body-wave seismograms indicated a rupture on a thrust fault that dips 49 degrees to the southwest and had a centroid depth of roughly . The rupture's mechanism of faulting was reverse. Multiple-event relocation of the main shock and aftershock epicenters and discontinuous surface ruptures recorded after the earthquake are compatible with northeastward movement on a southwest-dipping thrust, although maximum recorded displacements were less than would have been expected from the observed magnitude.

In principle, any physical system can be described by the many-body Schrödinger equation as long as the constituent particles are not moving "too" fast; that is, they are not moving at a speed comparable to that of light, and relativistic effects can be neglected. This is true for a wide range of electronic problems in condensed matter physics, in Bose–Einstein condensates and superfluids such as liquid helium. The ability to solve the Schrödinger equation for a given system allows prediction of its behavior, with important applications ranging from materials science to complex biological systems. The difficulty is however that solving the Schrödinger equation requires the knowledge of the many-body wave function in the many-body Hilbert space, which typically has an exponentially large size in the number of particles.

The earthquake produced shaking at Pangandaran (where the M6.3 2006 Yogyakarta earthquake was felt more strongly) of intensity III–IV (Weak–Light), intensity III at Cianjur, and II (Weak) at Yogyakarta. Further inland and farther from the epicenter, intensity IV shaking made tall buildings sway in Jakarta, but at some coastal villages where many of the casualties occurred, the shaking was not felt as strong. An informal survey of 67 people that were present at the time revealed that in at least eight cases, individuals stated that they did not feel the earthquake at all (a typical M7.7 earthquake would have been distinctly noticed at those distances). The unusually low felt intensities, along with the short period body wave magnitudes, were components of the event that narrowed its classification into that of a tsunami earthquake.
