I know some one who was there in 1964 and he is the one who told me about the Fairbanks area with large cracks and the 'slough' - 'creeks' to us that drained into them for quite a while. This one gives the line of the Denali which was the largest inland ever in the US. I know there were several small quakes in the Fairbanks area in about 1970 when I lived there that we noticed. The one below is a map which shows it is a mess all the way fro the west most islands across the bottom of Alaska to the line that curves down the north south edge of Canada and the other area of Alaska. http://www.aeic.alaska.edu/vltpage3.html Earthquakes of large magnitude occur at depth along the Aleutian Megathrust; the fault surface on which the Pacific Plate slides beneath Alaska as it is subducted into the earth's mantle. Earthquakes of small to large magnitude are also distributed throughout southeastern, southcentral, interior, and northern Alaska at shallower depths within the crust
