Earthquakes are not a norm here on the east coast of the United States. Even a relatively small earthquake can cause quite a disruption. On August 23, 2011, Mineral, Virginia experienced a 5.8 magnitude earthquake that was felt throughout the east coast. The Washington D.C., metro area being less than 90 miles away, felt the quake as well. Most buildings in the D.C. area were evacuated since corporations and agencies were not sure how well the buildings would hold up structurally. The east coast is not designed to withstand seismic activity. As the quake occurred, most people in D.C. did not think it was an earthquake at first. Their initial response was that it was a terrorist attack, which caused some panic in some areas. The same effect occurred in New York City as well, where many buildings were evacuated. There was some damage that was reported at various locations in D.C., with the National Cathedral as one of them. Most of the damage that occurred was the result of things falling or tipping over, and some brick walls that collapsed.
