{{TOC left}}{{clear}}

A buried rupture earthquake, or blind earthquake (c.f., surface rupture 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.

Buried rupture earthquakes and ground motion

Recorded ground motions of large surface-rupture earthquakes are weaker than the ground motions from buried rupture earthquakes.[1]

How deep they occur

The asperity for a buried rupture earthquakes is in area deeper than roughly {{convert|5|km|mi}}. Examples are the Loma Prieta earthquake, Northridge earthquake, and the Noto Hanto earthquake.[3]

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.[4]
