What made the 1964 Alaska earthquake special at the time it happened?

Studies of ground motion have led to a peak ground acceleration estimate of 0.14–0.18 g. The Alaska earthquake was a subduction zone (megathrust) earthquake, caused by an oceanic plate sinking under a continental plate. The fault responsible was the Aleutian Megathrust, a reverse fault caused by a compressional force.
