Buried rupture earthquake


A buried rupture earthquake, or blind earthquake is an earthquake with non-visible offset of the ground surface when an earthquake rupture along a fault does not affect the Earth's surface. See also blind thrust earthquake, a close concept.
's collapsed upper deck and failed support columns, from the 1989 Loma Prieta earthquake, which was a buried rupture earthquake, but causes massive surface damage

Buried rupture earthquakes and ground motion

Recorded ground motions of large surface-rupture earthquakes are weaker than the ground motions from buried rupture earthquakes.

How deep they occur

The asperity for a buried rupture earthquakes is in area deeper than roughly. Examples are the Loma Prieta earthquake, Northridge earthquake, and the Noto Hanto earthquake.

Buried rupture earthquakes and tsunamis

Uplifted water outside the fault plane in the buried rupture case, as compared to the seabed surface rupture case, makes for large tsunami waves.
