Causes of earthquake:
1 Groundwater extraction – decrease in pore pressure
2. Groundwater – increase in pore pressure.
3. Heavy rain.
4. Pore fluid flow.
5. High CO2 pressure.
6. Building dams.
Effects of earthquake:
1. Loss of lives
2. Increase in government expenditure
3. Loss of properties
Protection against earthquake:
We cannot prevent natural earthquakes from occurring but we can significantly mitigate their effects by identifying hazards, building safer structures, and providing education on earthquake safety. By preparing for natural earthquakes we can also reduce the risk from human induced earthquakes.
