Shear Stress.
There are a few ways this can happen. First, earthquakes are associated with movement along faults. This movement can alter the surface terrain. The shaking of an earthquake can also cause wet soil and sediment to behave like a liquid.
It all depends on how big the fault is, bigger ones will cause bigger earthquakes, while smaller, or small ones may cause no earthquake at all.

The are both related to the movement of tectonic plates.
All faults are associated with stress, as summarised below: Normal faults - tensile stress Reverse / thrust faults - compressive stress Strike slip faults - shear stress
The stress that causes strike-slip faults is produced by a shearing force and so is called shear stress.
The stress that causes strike-slip faults is produced by a shearing force and so is called shear stress.
Movement of tectonic plates which are parts of the Earth's crust.
Stress and faults are both caused by tectonic plates.
Folding is usually the result of compressional stress. This may also cause thrust / reverse faults.
Strike slip faults and transform faults are associated with shear stress.

The main direction of the stress on blocks of rock at normal faults, reverse faults and the strike slip faults usually happens at the weak areas.
