It suggests that elastic strain energy builds up in the deforming rocks on either side of the fault
A
EARTHQUAKE THEORY
B
PLATE TECTONICS
C
SUBDUCTION ZONE
D
ELASTIC REBOUND THEORY
Explanation: 

Detailed explanation-1: -The elastic rebound theory states that as rocks on opposite sides of a fault (which is a fracture or a zone of fractures between two blocks of rock) shift from pressure applied to them, they will gradually gain energy and deform.

Detailed explanation-2: -The elastic rebound theory suggests that if slippage along a fault is hindered such that elastic strain energy builds up in the deforming rocks on either side of the fault, when the slippage does occur, the energy released causes an earthquake.

Detailed explanation-3: -Elastic rebound is what happens to the crustal material on either side of a fault during an earthquake. The idea is that a fault is stuck until the strain accumulated in the rock on either side of the fault has overcome the friction making it stick.

Detailed explanation-4: -If a stretched rubber band is broken or cut, elastic energy stored in the rubber band during the stretching will suddenly be released. Similarly, the crust of the earth can gradually store elastic stress that is released suddenly during an earthquake.

Detailed explanation-5: -Elastic rebound theory Before an earthquake, the buildup of stress in the rocks on either side of a fault results in gradual deformation. Eventually, this deformation exceeds the frictional force holding the rocks together and sudden slip occurs along the fault.
