Earthquake Hazards

Definition

Earthquake hazard describes what level of ground shaking at the Earth's surface is expected due to potential future earthquakes.

Various Potential Earthquake Hazards

1. Ground Rupture

Deformation on the ground that marks the intersection of the fault with the earth's surface.

2. Ground Shaking

Disruptive up, down, and sideways vibration of the ground during an earthquake.

3. Liquefaction

Occurs when loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking.

4. Earthquake-induced Landslide

A mass movement of material, such as rock, earth, or debris, down a slope due to an earthquake.

5. Tsunami

A series of extremely long waves caused by a large and sudden displacement of the ocean, usually as a result of an earthquake below or near the ocean floor.

Planetary Analogies in Earthquake Context

Mercury - Closest planet to the sun.

Venus - Second planet from the sun but known for its hot and poisonous atmosphere.

Jupiter - The largest planet in the solar system.

Saturn - Notable for its rings.

Mars - Despite its color, it is quite cold.

Conclusion

Understanding earthquake hazards is crucial for disaster preparedness and risk reduction.
