Benioff Zone 2
Benioff Zone 2 : ?A dipping planar zone of earthquakes that is produced by the interaction of a downgoing oceanic crustal plate with a continental plate. These earthquakes can be produced by slip along the subduction thrust fault (sometimes referred to as the thrust interface fault because it is the interface between the continental plate and the oceanic plate) or by slip on faults within the downgoing plate as a result of bending and extension as the plate is pulled into the?mantle. Slip may also initiate between adjacent segments of downgoing plates. The Benioff zone in the Pacific Northwest is not as well developed as it is in other subduction zones. The earthquakes in this region do not appear to be produced by slip along the thrust fault. See also (known as the): Wadati-Benioff zone
