... At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacing the ground. Earthquakes occur due to faults in the Earth's crust, the uppermost layer of the Earth. This happens when there is discontinuity in the rock, so it appears as if there are two plates sliding or sl ...

How are seismic waves generated-Elastic rebound theory Describe
... 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 of an earthquake. If the seismograp ...
