GEOLOGY

Detailed explanation-1: -Earthquakes can result in the ground shaking, soil liquefaction, landslides, fissures, avalanches, fires and tsunamis. The extent of destruction and harm caused by an earthquake depends on: magnitude.

Detailed explanation-2: -Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Detailed explanation-3: -Earthquakes are caused by the slow deformation of the outer, brittle portions of “tectonic plates", the earth’s outermost layer of crust and upper mantle.

Detailed explanation-4: -An earthquake is the shaking of the surface of the earth due to the sudden release of energy in the earth’s crust. As a result, seismic waves (also known as S waves) are created. The seismic activities in an area determine the type and intensity of the earthquake.
