1. GLG 410 FINAL PROJECT: VA EARTHQUAKE ANALYSIS

2. Introduction:  August 23 rd, 2011 a magnitude 5.8 earthquake struck in Louisa County, 5 miles SSW from Mineral, VA.  Largest earthquake east of the Rocky Mountains since 1897.  The quake was felt from South Carolina to Maine, and even closed parts of DC.

3. Geology of Piedmont Region  The earthquake occurred in the VA seismic zone, in the Piedmont Region.  Originally formed as zone of repeated continental collision that created the Appalachian Mountains.  Numerous reverse faults formed during periods of orogeny were reactivated during Mesozoic extension.

4. Faults  Epicenter lies between Spotsylvania fault and Chopawamsic Fault.  Earthquake shows reverse slip faulting on a north to northeast striking fault plane (~5-15km long slip)
