Whole Lotta Shakin': An Examination of America's Earthquake Early Warning System Development and Implementation, Hearing Before the U.S. House of Representatives Committee on Natural Resources, Subcommittee on Energy and Mineral Resources, One Hundred Thirteenth Congress, Second Session, June 10, 2014 [open pdf - 3MB]
This testimony compilation is from the June 10, 2014 hearing on "An Examination of America's Earthquake Early Warning System Development and Implementation" held before the U.S. House Committee on Natural Resources. From the opening statement of Doug Lamborn: "In March we held a hearing on the fiftieth anniversary of the Good Friday Great Alaska Earthquake to look at advances in earthquake science over the ensuing half century. The Great Alaska Earthquake 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. As a result, it is one of the most studied natural disasters in history. Today, the committee will focus on the development and implementation of an Earthquake Early Warning System for the Western United States. You might be surprised to learn that an earthquake early warning system was proposed for San Francisco back in 1868. The suggestion that as shaking occurred in Hollister, CA a telegram could be sent to City Hall in San Francisco where an alarm - bells - could be rung to alert residents that imminent shaking was about to start so they might take measures to protect themselves. Hollister is about 74 miles southeast of San Francisco. Even back in the 1860s scientists knew that an electric signal transmits more quickly than seismic waves caused by an earthquake." Statements, letters, and materials submitted for the record include those of the following: Bill Leith, John D. Schelling, Douglas Toomey, Richard Allen, and John McPartland.
