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

B[edit]

  • Blind thrust earthquake, an earthquake which occurs along a thrust fault that does not show signs on the Earth's surface, hence the designation "blind"

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

D[edit]

E[edit]

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

F[edit]

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

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

I[edit]

  • Induced seismicity, typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earth's crust
  • Interplate earthquake, an earthquake that occurs at the boundary between two tectonic plates
  • Intraplate earthquake, earthquake that occurs within the interior of a tectonic plate

M[edit]

  • Megathrust earthquake, earthquake occurring at subduction zones at destructive convergent plate boundaries, where one tectonic plate is forced underneath another

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
  • Submarine earthquake, an earthquake that occurs underwater at the bottom of a body of water, especially an ocean
  • 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

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

V[edit]
