Buried rupture earthquake

The Northridge earthquake was a buried rupture earthquake,[1] which caused massive surface damage

In seismology, a buried rupture earthquake, or blind earthquake, is an earthquake which does not produce a visible offset in the ground along the fault (as opposed to a surface rupture earthquake, which does). When the fault in question is a thrust fault, the earthquake is known as a blind thrust earthquake.
