Buried rupture earthquake

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