Most earthquakes result from the release of energy generated by the pressure exerted by a moving plate.

The longer the pressure was becoming enlarged and eventually reach the state where the pressure can not be arrested again by the edge of plate. That's when an earthquake will occur.

At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacing the ground. When a large earthquake epicenter is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami. The shaking in earthquakes can also trigger landslides and occasionally volcanic activity. 

Earthquakes occur every day on Earth, but the vast majority of them are minor and cause no damage. Large earthquakes can cause serious destruction and massive loss of life, but for most earthquakes shaking is the dominant and most widespread cause of damage. 

There is no known way to prevent earthquakes, but it is possible to lessen the impact. The amount of devastation from an earthquake can be greatly diminished by building structures using earthquake resistant design, making the interiors of buildings safe from falling objects, and educating people about earthquake safety.
