Effects of the 1964 Alaskan Earthquake on Glaciers and Related Features
Keywords:Koch, Lauge, 1892-1964
AbstractDescribes an aerial photographic reconnaissance in Apr and Sept 1964 of the approx 30,000 sq mi area most seriously affected by the Mar 27 earthquake to assess the extent to which glacial features had been modified. Little change was apparent in glacial basins, lakes or tidewater calving, much less than after the 1899 and 1958 earthquakes of comparable violence. Some rock slides on to glaciers were impressive. The effects are related to the Tarr and Martin (No 17449) theory of earthquake avalanche supply, but it may be several years before evidence to test the applicability of the theory to the 1964 earthquake is apparent. 25 air photos with detailed descriptive notes illus the features described. Condensed version of the text was pub in Arctic 1965. v 18, no 2, p. 135-37.
