Aug 5, 2023 · Earthquake. An earthquake is a violent and abrupt shaking of the ground, caused by movement between tectonic plates along a fault line in the earth's crust. Earthquakes can result in ground shaking, soil liquefaction, landslides, fissures, avalanches, fires, and tsunamis. Of the earthquake-prone areas,12% are prone to very severe and 18% to ...
An earthquake in simple words is the shaking of the earth. It is a natural event. It is caused due to release of energy, which generates waves that travel in all directions. The vibrations called seismic waves are generated from earthquakes that travel through the Earth and are recorded on instruments called seismographs.
Earthquakes based on the depth of focus. The earthquakes are divided into three zones: shallow, intermediate, and deep based on their depth which range between 0 – 700 km. Shallow earthquakes have a focus 0 – 70 km deep. Intermediate earthquakes have a focus 70 – 300 km deep. Deep earthquakes have a focus 300 – 700 km deep. Wadati ...
Dec 13, 2019 · Seismic waves. Seismic: relating to earthquakes or other vibrations of the earth and its crust. Seismic waves are waves of energy that travel through the Earth’s layers and are a result of earthquakes, volcanic eruptions, magma movement, large landslides and large human-made explosions. The refraction or reflection of seismic waves is used ...
Mar 8, 2024 · An earthquake is a quick shaking or trembling of the earth’s surface brought on by seismic waves or earthquake waves that are produced as a result of an abrupt movement (an abrupt release of energy) in the earth’s crust (earthquakes with shallow foci) or upper mantle (some shallow-focus and all intermediate and deep-focus earthquakes).
Jun 21, 2024 · Causes of Earthquakes: Earthquakes result from a series of earth movements brought about by a sudden release of energy during the tectonic activities in the earth’s crust. Earthquakes due to other causes: It could also be triggered by volcanic eruption, rock falls, landslides, subsidence, particularly in the mining areas, impounding of dams ...
Nov 14, 2023 · Earthquake UPSC. An earthquake is a potential natural hazard. The world does not inevitably endure significant shocks, as was previously noted. High-magnitude earthquakes, namely those that are 8 or more, happen just a few times per one to two years. The topic of earthquakes and their types are extensively covered under the Geography syllabus ...
