Gravity Survey and Regional Geology of the Prince William Sound Epicentral Region, Alaska [open pdf - 9MB]
"Following the Alaska earthquake of March 27, 1964, the U.S. Geological Survey made an intensive investigation of the effects of the earthquake in the Prince William Sound region where the epicenter was located. Concurrent investigations included studies of the regional geology, changes of land level, faulting, and effects of waves on shorelines which were summarized by Plafker and Mayo (1965). At the same time, this gravity survey, mentioned briefly by Barnes and Allen (1965), was conducted in order to establish the regional geologic and tectonic setting of the earthquake. Geologic sections of this report were prepared by Plafker and Case, the gravity sections by Case, Barnes, and Robbins."
