Study Notes
Earthquakes
- Earthquakes are one of the most deadly natural hazards, causing catastrophic loss of human lives and economic damage.
- An earthquake is a vibration through the earth's crust, resulting from powerful movement of rocks in the earth's crust.
Causes of Earthquakes
- The powerful movement of rocks in the earth's crust triggers a rapid release of energy, creating seismic waves that travel through the earth.
Characteristics of Earthquakes
- Earthquakes are usually brief, but may repeat over a long period of time.
- Large earthquakes begin with slight tremors, rapidly developing into violent shocks.
- The vibrations from a large earthquake last for a few days, known as aftershocks.
- Small earthquakes are usually slight tremors, causing little to no damage.
Effects of Earthquakes
- Large earthquakes can cause buildings to collapse, resulting in death and injury.
Statistics
- There are approximately 500,000 earthquakes every year.
- Only about 100,000 of these earthquakes can be felt.
- Around 100 earthquakes can cause damage each year.
