Quake (natural phenomenon)

A quake is the result when the surface of a planet, moon or star begins to shake, usually as the consequence of a sudden release of energy transmitted as seismic waves, and potentially with great violence.
The types of quakes include:
Earthquake.
An earthquake is a phenomenon that results from the sudden release of stored energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes cause tsunamis, which may lead to loss of life and destruction of property. An earthquake is caused by tectonic plates (sections of the Earth's crust) getting stuck and putting a strain on the ground. The strain becomes so great that rocks give way and fault lines occur.
Moonquake.
A moonquake is the lunar equivalent of an earthquake (i.e., a quake on the Moon). They were first discovered by the Apollo astronauts. The largest moonquakes are much weaker than the largest earthquakes, though their shaking can last for up to an hour, due to fewer attenuating factors to dampen seismic vibrations.
Information about moonquakes comes from seismometers placed on the Moon from 1969 through 1972. The instruments placed by the Apollo 12, 14, 15 and 16 missions functioned perfectly until they were switched off in 1977.
There are at least four kinds of moonquake:
The first three kinds of moonquakes mentioned above tend to be mild; however, shallow moonquakes can register up to mB=5.5 on the body-wave magnitude scale. Between 1972 and 1977, 28 shallow moonquakes were observed. Deep moonquakes tend to occur within isolated kilometer-scale patches, sometimes referred to as nests or clusters.
Marsquake.
A marsquake is a quake that occurs on the planet Mars. A 2012 study suggests that marsquakes may occur every million years. This suggestion is related to evidence found then of Mars's tectonic boundaries. A tremor believed to be a possible marsquake was first measured by NASA's InSight lander on April 6, 2019, which was one of the lander's key science goals.
Venusquake.
A venusquake is a quake that occurs on the planet Venus.
A venusquake may have caused a new scarp and a landslide to form. An image of the landslides was taken in November 1990 during the first flight around Venus by the "Magellan" spacecraft. Another image was taken on July 23, 1991 as the "Magellan" revolved around Venus for the second time. Each image was across and long, and was centered at 2° south latitude and 74° east longitude. The pair of "Magellan" images shows a region in Aphrodite Terra, within a steeply sloping valley that is cut by many fractures (faults).
Sunquake.
A sunquake is a quake that occurs on the Sun.
Seismic waves produced by sunquakes occur in the photosphere and can travel at velocities of for distances up to before fading away.
On July 9, 1996, a sunquake was produced by an X2.6 class solar flare and its corresponding coronal mass ejection. According to researchers who reported the event in "Nature", this sunquake was comparable to an earthquake of a magnitude 11.3 on the Richter scale. That represents a release of energy approximately 40,000 times greater than that of the devastating 1906 San Francisco earthquake, and far greater than that of any earthquake ever recorded. Such an event contains the energy of 100-110 billion tons of TNT or 2 million modest sized nuclear bombs. It is unclear how such a relatively modest flare could have liberated sufficient energy to generate such powerful seismic waves.
The ESA and NASA spacecraft SOHO records sunquakes as part of its mission to study the Sun.
Starquake.
A starquake is an astrophysical phenomenon that occurs when the crust of a neutron star undergoes a sudden adjustment, analogous to an earthquake on Earth. Starquakes are thought to result from two different mechanisms. One is the huge stresses exerted on the surface of the neutron star produced by twists in the ultra-strong interior magnetic fields. A second cause is a result of spindown. As the neutron star loses linear velocity due to frame-dragging and by the bleeding off of energy due to it being a rotating magnetic dipole, the crust develops an enormous amount of stress. Once that exceeds a certain level, it adjusts itself to a shape closer to non-rotating equilibrium: a perfect sphere. The actual change is believed to be on the order of micrometers or less, and occurs in less than a millionth of a second.
The largest recorded starquake was detected on December 27, 2004 from the ultracompact stellar corpse SGR 1806-20. It has been calculated that the energy release would be equivalent to a magnitude 32 quake on Earth. The quake, which occurred 50,000 light years from Earth, released gamma rays equivalent to 1037 kW. Had it occurred within a distance of 10 light years from Earth, the quake could have triggered a mass extinction.
Ice quake.
Cryoseisms are not triggered by tectonic events, such as shifting tectonic plates or rising magma. They occur when liquid groundwater saturates pores in the soil and cools rapidly to solid ice. Water is at its densest at 4 °C (39.2 °F), and it expands when it freezes. The freezing of water and its subsequent expansion begin at the surface and continue downward into the soil. Ice forming at or near the surface creates a barrier that hinders the release of pressure that builds up in the surrounding rock as well as in the frozen soil below. The pressure may increase until the rock and soil fracture under the stress. The sudden release of energy that results may be strong enough to produce audible booming sounds (called cryoseismic booms) and seismic waves (which may be recorded by seismographs).
