Hint: When accumulated energy in the Earth's crust is abruptly released, seismic waves are generated. At the Earth's surface, earthquakes can produce ground shaking or displacement. They can sometimes create tsunamis, which can result in loss of life and property devastation.
Complete answer:
An earthquake is a tremor on the Earth's surface caused by a rapid release of energy in the lithosphere, which causes seismic waves. Earthquakes may range in size from being too little to be felt to being powerful enough to toss objects and people into the air and destroy entire towns. Seismicity, or seismic activity, is defined by the number, kind, and size of earthquakes that occur throughout time. Tremor is a term used to describe non-earthquake seismic rumbling.
Earthquakes cause shaking and shifting or disturbing of the ground at the Earth's surface. The seafloor may be moved enough to create a tsunami when the epicentre of a major earthquake is located offshore. Landslides and, on rare occasions, volcanic activity can be triggered by earthquakes.
Animal behaviour is one of the most popular earthquake prediction methods; fish in ponds become agitated, and snakes rise to the surface. In order to understand how to forecast earthquakes, several approaches have been explored. Seismicity changes, changes in seismic wave speed, electrical changes, and groundwater alterations are some of the most serious techniques that have been investigated.
Note: "Seismicity changes" is just a fancy way of saying "foreshocks." A foreshock is a minor earthquake that happens "near" the epicentre of a bigger earthquake before it. The difficulty with earthquake prediction is that not all earthquakes produce foreshocks, and we haven't yet figured out how to identify if a mild one will.
