2003 earthquakes
On December 9, 2003 at 3:59 p.m. EST (20:59 UTC), a magnitude 4.5 event occurred near Farmville, about 30 miles (48 kilometers) west of Richmond, Virginia, and was felt strongly across Virginia. Tremors were reported in North Carolina, the District of Columbia, and suburban Maryland, eastern West Virginia, southern Pennsylvania, and portions of the Delmarva Peninsula. This event was located at 37.728° N, 78.087° W, at a depth of less than 5 km (3 miles) and may have occurred due to rupture along the Lakeside fault.[7]
The December earthquake was preceded by a magnitude 3.8 event on May 5, 2003 whose epicenter was located approximately 40 miles NNE near Cartersville, VA.[8]
2011 earthquake
The U.S. Geological Survey reported that a magnitude 5.9 Mw earthquake hit Virginia on Tuesday, August 23, 2011 at 17:51:04 UTC. The quake occurred at an approximate depth of 3.7 miles and was centered in Louisa County (location at 37.936°N, 77.933°W), 5 miles SSW of Mineral and 38 miles NW of Richmond.[9] Shaking was felt from from Atlanta, GA to Windsor, Canada and neighboring Detroit, MI. The Pentagon and the US Capitol were evacuated as a precaution.[10] It was also felt in parts of Canada.[11] News from as far East as Cincinnati, Ohio have reported feeling shakes from the earthquake.
