Supplementary Virtual Presentations on Advances in Studies of Intraplate Tectonics
Symposium Convenor: Gerry L. Stirewalt, PhD, PG, CEG
This exciting virtual 4-hour session, planned and convened by Dr. Gerry L. Stirewalt, Co-Chair of AEG’s Geologic and Seismic Hazards Technical Working Group (GASH TWG), showcases four (4) speakers with information to share that expands the number of intraplate tectonic sources being discussed during the in-person 25 September Symposium on “Advances in Studies of Intraplate Tectonics”. This virtual session, organized to allow inclusion of these sterling speakers who were unable to attend the Annual Meeting but have fascinating data to present that is sure to be of keen interest to attendees, specifically includes the following topics:
-
Geology of the Reelfoot Rift and It’s Earthquakes Beneath the Mississippi River Valley - Roy Van Arsdale, University of Memphis
-
Methods for Studying Earthquake Hazards in the New Madrid Seismic Zone in West Tennessee - Valerie J. Harrison, Tennessee Geological Survey
-
Looking High and Low for Active Intraplate Faults in the Charleston Seismic Zone in South Carolina by Combining Geophysical Datasets - Anjana K. Shah, U.S. Geological Survey
-
The Mw 5.1 Sparta, North Carolina, Surface Rupturing Earthquake and Evidence for Recurrent Quaternary Deformation - Paula M. Figueiredo, North Carolina State University and Institute Dom Luis, Lisbon, Portugal
This virtual session provides attendees with the opportunity to learn more about how data emerging from investigations conducted in the specified intraplate tectonic areas are enhancing understanding of intraplate geologic hazards from faulting and associated seismicity. Your enthusiastic convenor, G. Stirewalt, believes this opportunity to listen, learn, and exchange ideas with these four expert geoscientists is absolutely too good to miss! DON’T MISS THIS GREAT SUPPLEMENTARY VIRTUAL SESSION!
