PGS: Sumy on induced earthquakes

Please join us for the December 14, 2017 meeting of the Potomac Geophysical Society at 7:00 p.m. at DoubleTree by Hilton McLean Tysons, 1960 Chain Bridge Road, 22102.  This location is within one-half mile of the Tysons Corner Metro station, near I-495, and has free parking available.  Our private meeting room is located in the back of the Orchard Cafe restaurant on the second floor of the hotel. The optional dinner cost will be discounted to $30 for members in good standing (have paid dues) and students, and $40 for non-members, and is inclusive of iced tea, coffee, tax and gratuity. Members and guests may attend the presentation after dinner for no charge; we estimate that the presentation will begin at 8:15 p.m.  For attendees who arrive early, the social will be held in O’Malley’s Pub on the first floor of the DoubleTree by Hilton hotel.  Drinks may also be purchased in the private meeting room on a cash basis.

This Month’s Speaker:

Danielle Sumy, PhD

Induced Earthquakes: Past Lessons and Future Research Directions

Hydraulic fracturing, wastewater injection, reservoir impoundment, and geothermal activity, to name a few, are all known causes of induced earthquakes around the world. Small to moderate events in Ohio, Colorado, Texas, Arkansas, and Oklahoma have shed light on the induced earthquake issue in the central and eastern United States over the past decade. These earthquakes have been particularly newsworthy and well investigated, and have created debate amongst communities on how to best regulate the causes and mitigate the risk of earthquake activity. In this talk, I will provide a general overview on the history and mechanisms that induce earthquake activity, discuss my own research on the 2011 Prague, Oklahoma events and the research of others, and look forward to the future in the context of how these recent discoveries shape the dialogue between government regulators, community leaders, and the public.

Biography: Dr. Danielle Sumy earned her PhD from the Lamont-Doherty Earth Observatory at Columbia University in 2011 in marine geology and geophysics, where she specifically focused on the hydraulic mechanisms of earthquake activity at mid-ocean ridge hydrothermal systems. She brought that expertise to the subject of induced seismicity during her postdoctoral fellowships at the USGS in Pasadena, CA and at the University of Southern California. In 2014, she joined the IRIS Consortium, a National Science Foundation large facility that focuses on the operations and management of regional and global seismic networks and the storage of data from these networks, as well as education and outreach efforts to students, professionals, and the public
