Essay on Natural Disaster Earthquake

An earthquake is simply called the shaking of the Earth's surface. It's a sudden trembling of the Earth's surface. Earthquakes are unquestionably deadly natural disasters. Earthquakes can also cause significant damage to people and property. 

Some Earthquakes are minor in magnitude and go unnoticed. Some Earthquakes, on the other hand, are large and violent. Earthquakes of this magnitude are nearly always deadly in nature. Most importantly, an earthquake's occurrence is highly unpredictable and that's why they're so hazardous.

Types Of Earthquake

There are four types of earthquakes which we have discussed below:

1. Tectonic Earthquake

The Earth's crust is made up of a slab of unevenly shaped rocks. Tectonic plates are these rock slabs. In addition, there is energy stored in this location. Tectonic plates push away from or towards one other as a result of this energy. As time passes, the energy and movement between the two plates build up pressure.

As a result of this huge pressure, the fault line forms. The Earthquake's focus is also at the core of this disruption. As a result, energy waves move from the focus to the surface. The surface begins to shake as a result of this.

2. Earthquake Caused By Volcanic Activity

This Earthquake was caused by volcanic activity. Above all, the magnitude of such tremors is insignificant. These are two kinds of earthquakes. Volcano-tectonic earthquakes are the first category. Tremors occur as a result of Magma injection or withdrawal. 

On the other hand, Long-period earthquakes are the second category. Earthquakes occur here as a result of pressure differences between the Earth's strata.

3. Earthquake Of Collapse

These Earthquakes happen in caves and mines. Furthermore, the magnitude of these Earthquakes is minor. Mine collapses are most likely caused by underground explosives. Above all, mine collapses result in seismic waves. As a result of these seismic waves, an earthquake occurs.

4. Explosive Earthquake

These quakes almost invariably happen as a result of nuclear weapons testing. A large explosion occurs when a nuclear weapon is detonated. This causes a massive amount of energy to be released. Earthquakes are more likely to occur as a result of this.

Impacts Of Earthquake

1. The most noticeable impact of the Earthquake is the ground shaking.

2. Landslides are another severe result of the earthquake. Slope instability causes landslides.

3. Soil liquefaction can occur as a result of earthquakes. This occurs when granular material that has been saturated with water loses its strength.

4. Fires can occur as a result of earthquakes. This is due to the damage to the electric power and gas lines caused by the earthquake.

5. Tsunamis can also be caused by earthquakes. Tsunamis are sea waves with a large wavelength. This is due to an earthquake that occurred in the ocean.

Conclusion

Finally, an Earthquake is a massive and terrible natural occurrence on the planet. It is an incredible occurrence that amazes everyone. It demonstrates human helplessness in the face of nature. Above all, an earthquake can create unthinkable destruction in a matter of seconds.
