write essay on earthquake.
Answers
First of all, the shaking of the ground is the most notable effect of the Earthquake. Furthermore, ground rupture also occurs along with shaking. This results in severe damage to infrastructure facilities. The severity of the Earthquake depends upon the magnitude and distance from the epicenter. Also, the local geographical conditions play a role in determining the severity. Ground rupture refers to the visible breaking of the Earth’s surface.
Another significant effect of Earthquake is landslides. Landslides occur due to slope instability. This slope instability happens because of Earthquake.
Earthquakes can cause soil liquefaction. This happens when water-saturated granular material loses its strength. Therefore, it transforms from solid to a liquid. Consequently, rigid structures sink into the liquefied deposits.
Earthquakes can result in fires. This happens because Earthquake damages the electric power and gas lines. Above all, it becomes extremely difficult to stop a fire once it begins.
Earthquakes can also create the infamous Tsunamis. Tsunamis are long-wavelength sea waves. These sea waves are caused by the sudden or abrupt movement of large volumes of water. This is because of an Earthquake in the ocean. Above all, Tsunamis can travel at a speed of 600-800 kilometers per hour. These tsunamis can cause massive destruction when they hit the sea coast.
In conclusion, an Earthquake is a great and terrifying phenomenon of Earth. It shows the frailty of humans against nature. It is a tremendous occurrence that certainly shocks everyone. Above all, Earthquake lasts only for a few seconds but can cause unimaginable damage.
Answer:
An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. ... In its most generic sense, the word earthquake is used to describe any seismic event—whether a natural phenomenon or an event caused by humans—that generates seismic waves.
