In seismology, a supershear earthquake is an earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity. This causes an effect analogous to a sonic boom. WebApr 2, 2024 · earthquakes that allows the time and magnitude of impending large earthquakes to be stress-forecast.
