The earth is a dynamic entity that is undergoing changes all the time. Normal changes such as those occurring to the weather and the seasons are part and parcel of living. We live our lives according to these changes regardless of whether we like it or not. However, sometimes the forces of nature cause great and drastic changes, and for us puny human beings, the effect can be disastrous!

The plates of the earth crust are not static. They push and grind against one another producing earthquakes that sometimes cause widespread destruction to the affected area.

No place on earth is totally free from disaster-causing events. We can only do our best to deal with these events when they occur. People and property are inevitably destroyed. Those who survive pick up the pieces and continue living.   

Hope my answer helps you buddy!  ;)
