A fault between the Pacific and North American plates ruptured near College Fjord in Prince William Sound. I find nothing that actually gives a name to the fault, but it is the boundary between the Pacific and North American plates.
The center of the Alaska earthquake was located about 75 miles east of Anchorage and about 55 miles west of Valdez. It began 14 to 16 miles deep in the earth’s crust, a comparatively shallow depth, where the Pacific plate dives beneath the North American plate. The huge subduction zone is located at the north end of the Ring of Fire, a semicircle of volcanic and earthquake activity that defines the rim of the Pacific Ocean.
The earthquake fault, more precisely the thrust fault, which was the cause of the Good Friday earthquake stretched 750 miles from Alaska’s Aleutian Islands to Valdez. The Pacific plate that day moved an estimated 25 to 30 feet northward, diving beneath the North American plate.

"The Alaska-Aleutian Megathrust Fault". The Great Alaska Earthquake on March 27, 1964 occurred at this fault."
Hope this helps you.
