How are seismic waves generated-Elastic rebound theory Describe
... What can seismic waves tell us? Studies of the different types of seismic waves can tell us much about the nature of the Earth’s structure. For example, seismologists can use the direction and the difference in the arrival times between P-waves and S-waves to determine the distance to the source o ...
