This is a list of different types of earthquake.

A edit

  • Aftershock, a smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock.[1][2]

B edit

C edit

  • Cryoseism, a seismic event that may be caused by a sudden cracking action in frozen soil or rock saturated with water or ice.[4]

D edit

  • 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 edit

  • Earthquake swarm, events where a local area experiences sequences of many earthquakes striking in a relatively short period of time.[7]

F edit

  • Foreshock, an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space.[8]

H edit

  • 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 edit

M edit

  • Megathrust earthquake, an earthquake occurring at subduction zones at destructive convergent plate boundaries, where one tectonic plate is forced underneath another.[14]

R edit

S edit

  • 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 edit

  • 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 edit
