What are four ways the earthquakes can cause damage?

1: Ground Shaking:

Causing structures to move from side to side, Causing buildings, houses ect. to collapse, slide of their foundation or even be shaken apart.

2: Earthquakes in water:

Earthquakes that erupt under water can cause a Tsunami on the nearest island or piece of land. This can kill people and animals and destroy houses, leaving people homeless.

3: It can trigger a land slide.

4: Can cause Liquefaction.

Hope this helps in someway for more information :
