'Magnitude 9.2: The 1964 Great Alaska Earthquake' (USGS video)

from U.S. Geological Survey via YouTube

VideoBrief"Magnitude 9.2: The 1964 Great Alaska Earthquake" is a short video relating how the largest quake in U.S. history had profound and lasting impacts on our lives. The video features U.S. Geological Survey geologist George Plafker, who, in the 1960s, correctly interpreted the quake as a subduction zone event. This was a great leap forward in resolving key mechanisms of the developing theory of plate tectonics. Loss of life and destruction from the quake and accompanying tsunamis was the impetus for things like the NOAA Tsunami Warning Centers and the USGS Earthquake Hazards Program. more
