Now, only 5 days after a Mag 7.0 earthquake shook the Cape Mendocino Fracture Zone offshore of the CA coast, aftershocks continue hourly. Over 420 earthquakes in this 110 km x 20 km region are already listed. More happen each hour. Why do hundreds of small earthquakes offshore of northern California matter?
