Explanation:

  • These plates are moving towards one another, but there are very few volcanoes in this area compared to other places in the world. Using this information, which pattern of earthquakes would you expect to see  here?
  • A. Earthquakes are shallow and spread out over a large area.
  • Most of the earthquakes are a result of faulty movements in the crust, a relatively thin layer on the surface of the earth.
  • In the region of Cascadia, most of the earthquakes are shallow quakes that occur within the crust of the North America plate to a depth of approximately 20 miles which is 35 km.
