S. Hrg. 110-454: The New Madrid Seismic Zone: Whose Fault Is It Anyway? Hearing before the Ad Hoc Subcommittee on State, Local and Private Sector Preparedness and Integration of the Committee on Homeland Security and Governmental Affairs, United States Senate, One Hundred Tenth Congress, First Session, December 4, 2007 [open pdf - 4MB]
From the opening statement of David Pryor: "I want to thank all of you for being here today for this hearing before the Ad Hoc Committee on State, Local, and Private Sector Preparedness and Integration. We are calling this hearing 'The New Madrid Seismic Zone: Whose Fault is it Anyway?' a little bit of a play on words. I know you earthquake researchers get tired of that play on words, but we couldn't resist. We are talking about a very serious subject today, one that touches my State very directly, as you can see from the map, and that is the New Madrid fault line. I want to welcome Dave Maxwell and thank him for being here. He is in the back of the room. He is on our next panel, but he is from my home State of Arkansas and we will give him the proper introduction in a few moments. As most people who follow earthquakes in this country and understand the history of earthquakes in this country, in 1811 and 1812, a series of three very large earthquakes struck the New Madrid region. The earthquakes measured between 7.0 and 8.0 on the Richter scale. The earthquakes were so powerful that they changed the course of the Mississippi River and the Mississippi River actually flowed backwards for some time. The tremors from the earthquakes could be felt as far away as 1,000 miles. In fact, there are recorded stories of church bells ringing in Boston because the ground was shaking in Boston, Massachusetts." Statements, letters, and materials submitted for the record include those of the following: David Pryor, Glenn M. Cannon, John R. Hayes, David Applegate, David Maxwell, and Callen Hays.
