the theory on the expansion of the earth's crust. By the earthquake was caused by tectonic plate's bend curved bend suddenly. And when the object detection and release energy in the form of seismic waves out
.The theory on restitution of the object. By the earthquake from the moves of the fault zone, that is, when the fault moves up to one point objects are torn apart and deformed greatly.And then the object will revert back to the original image.
