The resulting in the role of the crustal deformation of rocks , broken , dislocation and then the earthquake .
由此而产生力的作用，使地壳岩层变形、断裂、错动，于是便发生地震。
Most solids , if pulled or twisted , will give a little in a process known as elastic deformation .
大多固体，一经拉伸或弯曲，都会出现弹性变形这一过程。
This lava field just north of the mrdalsjkull ice cap serves as one of many monitoring sites to track ground deformation that could serve as a signal of an impending eruption of katla .
Geologists can accurately predict where ( but not when ) the next earthquake will happen by using satellite gravity measurements and tracing ground deformation caused by earthquakes .
