Intraslab (Benioff zone) earthquakes, such as the M 6.7 2001 Nisqually earthquake, caused by slippage or fracturing on a small part of the subducting plate at a depth of around 50 km (31 miles). Relatively shallow crustal earthquakes, generally less than 25 km (16 miles) deep, caused by stresses and faulting in the near-surface crustal structures.
