Webwhich governs seismic wave propagation outside of seismic source regions. Gener-ating solutions to (3.8) or (3.9) for realistic Earth models is an important part of seismology; such solutions provide the predicted ground motion at specific locations at some distance from the source and are commonly termed synthetic seismograms. WebThe slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate. That vibration pushes the adjoining piece of ground and causes it to vibrate, and thus the energy travels out from the earthquake hypocenter in a wave. There are many different ways to measure different aspects of an earthquake: h stern zephyr ring
