Destructive forces of earthquakes are-
- Collapse of structures causing great loss of life and property
- Submergence of coastal areas
- Changed course of rivers, rendering many areas unsuitable for irrigation and agriculture
- Resulting landslides disrupt the transport system
- Accidental fires cause damage to life and property
