Where would you be at the most risk of dealing with earthquakes on regular basis By:Annabelle

The pacific plate is moving northward toward Alaska. There are more earthquakes in Alaska then volcanos.  It is subducting under Alaska and the Aleution islands as well as the eastern most end of Siberia.  Alaska is known for oil, so lots of oil rings are located there.  With the oil rings they dig really deep changing the faultlines constantly, and the faultlines scrape against each other causing vibrations underground.  Alaska can have 24,000 earthquakes in one year.  Alaska is situated in a unique and complex tectionic setting.  At the southern edge of the state lies the boundary between the North America and Pacific plates.  In Southeast Alaska the plate boundary is defined by a series of strike-slip faults known as the Queen Charlotte-fairwether faults and continue through Canada and back into Alaska, creating some of the largest faults in the United States.
