Evenings Upstairs – The New Madrid Earthquakes of 1811-1812
Led by Dr. Nathan K Moran, Center for Earthquake Research and Information at the University of Memphis.
What many refer to as the Great New Madrid Earthquake, was actually a seismic event made up of 3 major quakes, followed by thousands of aftershocks, ranging from strong damaging quakes and diminishing to weaker quakes that lasted for years after the main shocks. The 3 main shocks were estimated at magnitudes 7.7, 7.5, and 7.7. As there were no seismograph stations in the region at that time, magnitude estimates vary widely (from 7.7 to 8.1) based on interpretation of journal accounts, damage reports, and descriptions of effects from that time.
Dr. Moran graduated from the University of Tennessee at Martin and earned his Ph. D. in history from the University of Memphis in 1999 in 19th century United States History.
He currently serves as a Research Associate at the Center for Earthquake Research and Information at the University of Memphis. His current work is focused on the cataloging of historic information for New Madrid and other earthquakes that occurred in the Central United States prior to the 20th century and compiling information for the New Madrid Compendium website.
The Center for Earthquake Research and Information (CERI) at the University of Memphis is devoted to understanding the causes and consequences of earthquakes and the structure and evolution of the continental lithosphere. CERI addresses these needs through cutting-edge research, comprehensive graduate student education, operation of state-of-the-art seismic and GPS networks, and dissemination of technical and practical information to the private and public sectors.
