Advances in Earthquake Science: 50th Anniversary of the Great Alaskan Quake: Hearing Before the U.S. House of Representatives, Committee on Natural Resources, Subcommittee on Energy and Mineral Resources, One Hundred Thirteenth Congress, Second Session, March 27, 2014   [open pdf - 2MB]

This is a compilation of the March 27, 2014 hearing on "Advances in Earthquake Science" held before the House Subcommittee on Energy and Mineral Resources. From the opening statement of Doug Lamborn: "Today marks the fiftieth anniversary of the Good Friday Great Alaska Earthquake. It was a massive 9.2 magnitude quake making it the second largest earthquake ever recorded with 'modern' seismic equipment, and the largest in the US. Technically, the earthquake occurred in the Aleutian Trench 'subduction zone' - although at the time the earthquake occurred 'subduction zone' was not a part of the geologic lexicon. The rupture occurred along a 580 mile stretch of the fault and lasted between 4 and 5 minutes. The earthquake caused the greatest amount of vertical uplift ever measured, almost 34 feet, and Southern Alaska moved more than 6S feet seaward. The earthquake also caused the largest tsunami to ever hit the west coast of the United States and Canada with the largest wave, 222 feet high, hitting Valdez at Shoup Bay." Statements, letters, and materials submitted for the record include those of the following: Doug Lamborn, William Leith, Lisa Grant Ludwig, John Vidale, and Reginald DesRoches.
