    What are the Effects of Earthquakes? | U.S. Geological Survey

    Ground Shaking. Ground shaking is a term used to describe the vibration of the ground during an earthquake. Ground shaking is caused by body waves and surface waves.As a generalization, the severity of ground shaking increases as magnitude increases and decreases as distance from the causative fault increases. Although the physics of seismic waves is complex, ground

    Oct 27, 2021 An earthquake is a sudden, rapid shaking of the ground caused by the shifting of rocks deep underneath the earth’s surface. Earthquakes can cause fires, tsunamis, landslides or avalanches. While they can happen anywhere without warning, areas at higher risk for earthquakes include Alaska, California, Hawaii, Oregon, Puerto Rico, Washington

    An earthquake is the violent shaking of the Earth caused by a sudden movement of rock beneath its surface. Rocks respond to stress (squeezed or pulled apart) near the Earth's surface by breaking, and when rocks move along either side of a fracture, it is called a fault

    The body of sand vibrates most readily in response to shaking that is close to its natural harmonic frequency, and liquefaction is also most likely to occur at that frequency. Earthquakes that take place beneath the ocean have the potential to generate tsunami.[ footnote]Tsunami is the Japanese word for harbour wave

Cassini in 1684 and is named after the titan Tethys of Greek mythology.. Tethys has a low density of 0.98 g/cm 3, the lowest of all the major moons in the Solar System, indicating that it is made of water ice with just a small fraction of rock
