Summary
[edit]| Description |
English: https://www.usgs.gov/media/videos/1964-quake-great-alaska-earthquake
"1964 Quake: The Great Alaska Earthquake" is an eleven minute video highlighting the impacts and effects of America's largest recorded earthquake. It is an expanded version of the four minute video "Magnitude 9.2". Both were created as part of USGS activities acknowledging the fifty year anniversary of the quake on March 27, 2014. The video features USGS geologist George Plafker, who, in the 1960's, 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. Landslide impacts and the extreme tsunami threat posed by these quakes are also discussed. Loss of life and destruction from the earthquake and accompanying tsunamis was the impetus for things like the NOAA Tsunami Warning Centers and the USGS Earthquake Hazards Program. |
