Elastic rebound
Explanation:
During a fault slip when rock units on either side returns to their original shape by generating vibrations, it is called elastic vibration. The elastic rebound theory gives the logic behind the formation and propagation of earthquakes.
- Seismic waves are elastic waves that originates from sudden and sharp move along a slipping fault.
- The rock can return back to its original position immediately.
- With time, it is known that stress builds up in a rock. Before a rock reaches its plastic limit, it reacts to the accumulated stress that tends to cause deformation.
- Stress in rocks causes the rock body to deform.
- A rock will rebound elastically before it finally deforms and it will return back to its original position.
- This is the elastic rebound theory.
