An inclined zone of earthquakes, plunging below the earth's surface at an angle between 30° and 80°, but commonly at around 45°, and extending to a depth of 300–400 km. Benioff zones are associated with the downward movement of a lithospheric plate at a destructive plate margin. See Scalera (2007) Geofísica Int. 46, 1.
