Field Observations on Effects of Alaska Earthquake of 10 July 1958

Abstract

The Alaska earthquake of 10 July 1958 was caused by movement on the Fairweather fault amounting to at least 21½ feet horizontally and 3½ feet vertically. Effects of strong shaking were evident over a large area in southeastern Alaska. In Lituya Bay an enormous wave, possibly resulting from a rockslide, reached a maximum height of more than 1700 feet.
