The corner frequency of the spectrum of particle acceleration in a seismic wave radiated by an earthquake source marks the transition between the low-frequency band, in which the spectrum rises as frequency squared, and the high-frequency band, in which the spectrum is flat. These two distinct...

Earthquake damage depends on the ground acceleration generated by ut, with this ground acceleration being directly proportional to the changes in rupture speed as a fault propagates. This is the primary motivation for seismologists to study earthquake fracture dynamics. The theoretical...
