Reconstituted Earthquake Ground Motion at Anchorage

Abstract

To aid analysis of the dynamic response of structures to the Alaska earthquake, a simulated accelerogram of the ground motion at Anchorage was constructed by combining information from a variety of secondary observations of the motion and its effects with knowledge of general earthquake ground motions. A maximum acceleration or approximately 15 percent of gravity is indicated. The strong ground shaking lasted for about 1 minute and was followed by approximately 3 minutes of lesser shaking.
