Session ID#: 20607

Session Description:
On 2016 September 3, a M5.8 earthquake occurred in Pawnee, Oklahoma. This is the largest earthquake in instrumented history in Oklahoma. Although Oklahoma has been seismically active in the past few years, this earthquake came as a surprise due to its lack of significant foreshock activity in the area. No strong aftershocks have been observed in the first week from the event. This session will focus on improving our scientific understanding of mid-continental intraplate seismicity especially for this M5.8 earthquake, and we invite contributions that include new observations, numerical modeling, and other pertinent studies. Topics including but not limited to: source rupture processes, geodetic and potential fields observations, aftershock studies, earthquake statistics, seismic hazard, petrophysical studies, and geophysical imaging. We seek contributions from diverse fields to facilitate a multi-disciplinary discussion.
