Understanding Earthquakes and Related Terminology
- Earthquake is caused by sudden release of energy in the earth's crust
- Seismograph is an instrument used to record ground shaking
- Stress refers to the force acting on rock
- Fault is a zone of fractures between two blocks of rocks
- Foot wall is the block below the plane of fault
- Hanging wall is the block above the plane of fault
- Tensional stress occurs when rock slabs are pulled apart, leading to reverse faults
