Types of earthquake
From Wikipedia, the free encyclopedia
This is a list of different types of earthquake.
A
- Aftershock, a smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock.[1][2]
B
- Blind thrust earthquake, an earthquake which occurs along a thrust fault that does not show signs on the Earth's surface.[3]
C
D
- Deep-focus earthquake, also called a plutonic earthquake, an earthquake with a depth exceeding 70 kilometres (43 mi).[5]
- Doublet earthquake, an earthquake that consists of at least two or more mainshocks of nearly identical magnitude, separated by a period of time.[6]
E
- Earthquake swarm, events where a local area experiences sequences of many earthquakes striking in a relatively short period of time.[7]
F
H
- Harmonic tremor, a sustained release of seismic and infrasonic energy typically associated with the underground movement of magma, the venting of volcanic gases from magma, or both.[9]
I
- Induced seismicity, typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earth's crust.[10]
- Interplate earthquake, an earthquake that occurs at the boundary between tectonic plates.[11]
- Intraplate earthquake, an earthquake that occurs within the interior of a tectonic plate.[12][13]
M
- Megathrust earthquake, an earthquake occurring at subduction zones at destructive convergent plate boundaries, where one tectonic plate is forced underneath another.[14]
R
- Remotely triggered earthquakes, a result of the effects of other earthquakes at considerable distance, outside of the immediate aftershock zones.[15]
S
- Slow earthquake, a discontinuous, earthquake-like event that releases energy over a period of hours to months, rather than the seconds to minutes characteristic of a typical earthquake.[16]
- Submarine earthquake, an earthquake that occurs underwater at the bottom of a body of water, especially an ocean.[17]
- Supershear earthquake, an earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity, causing an effect analogous to a sonic boom.[18]
- Strike-slip earthquake, an earthquake where two pieces of crust slide horizontally past each other.[19]
T
- Tsunami earthquake, an earthquake that triggers a tsunami of a magnitude that is very much larger than the magnitude of the earthquake as measured by shorter-period seismic waves.[20]
V
- Volcano tectonic earthquake, an earthquake induced by the movement (injection or withdrawal) of magma.[21]
