Nov 10, 2024 · Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another.
During an earthquake, the stored energy accumulated within the earth’s crust is suddenly released, leading to the rapid movement and displacement of rock masses along fault lines. This movement produces vibrations that propagate through the earth in the form of seismic waves.
In its most general sense, an earthquake is any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by the rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, fracking and nuclear tests.
Nov 22, 2022 · Earthquake is a natural phenomenon that manifests itself as a sudden shaking or trembling of the earth that lasts just a few seconds. It occurs as a result of disruption deep within the earth’s crust or as a result of disturbances within the earth’s crust.
The sudden shaking of the earth at a place for a short period is called an earthquake. The duration of the earthquake may last from a few seconds to a couple of minutes. The point where an earthquake originates is called its ‘focus’. The vertical point at the surface from the focus is called the ‘epicentre’. Suggest Corrections. 1.

An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
Nov 24, 2023 · An earthquake is the shaking caused by the rupture (breaking) and subsequent displacement of rocks (one body of rock moving with respect to another) beneath the Earth’s surface. Most earthquakes are a result of the stresses placed on rocks in areas where adjacent tectonic plates are moving in different directions.
