Title: The Earthquake of 1946: an investigation into the cause of the disastrous tsunami that followed
When: 24 July 2004
Who: Gerard Fryer (Univ of Hawaii)

Gerard Fryer is an Associate Geophysicist in the Hawaii Institute of Geophysics & Planetology, a unit within the School of Ocean & Earth Science & Technology at the University of Hawaii at Manoa.
Gerard talked about the eastern Aleutian earthquake of 1 April 1946 as perhaps the greatest enigma of seismology.ÊThe earthquake had a magnitude of "only" 7.1, yet it produced a tsunami almost as large as that from the Great Chile Earthquake of 1960 (magnitude 9.6). His explanation was that the source was not an earthquake at all but a landslide.
