GEOLOGY

Detailed explanation-1: –Landslides occur because of ground shaking in areas having relatively steep topography and poor slope stability.-Liquefaction of gently sloping unconsolidated material can be triggered by ground shaking. Flows and lateral spreads (liquefaction phenomena) are among the most destructive geologic hazards.

Detailed explanation-2: -Landslides are a type of “mass wasting, ” which denotes any down-slope movement of soil and rock under the direct influence of gravity.

Detailed explanation-3: -An earthquake is the shifting of the Earth’s plates, which results in a sudden shaking of the ground that can last for a few seconds to a few minutes.

Detailed explanation-4: -Earthquakes (a geological event) that occur under water can also trigger tsunamis (a hydrological event), such as the 2011 Japan Earthquake and Tsunami.

Detailed explanation-5: -When an earthquake occurs, the transmission of seismic waves can cause shaking and vibration of ground surface. This often trigger the collapse of potential landslide areas, which is known as earthquake-induced landslide.
