Where Do The Shallow Earthquakes Occur? |
|
Answer» Most earthquakes are a result of FAULT MOVEMENT in the crust, a RELATIVELY thin layer on the Earth's surface. In Cascadia, most earthquakes are shallow quakes that occur within the crust of the North America plate to a depth of about 20 miles (35 km).
