If you're at fault, have a plan
Earthquakes are no surprise in the western United States, but the eastern and central regions have a rumbling reputation of their own. Although earthquakes are less frequent in these parts of the country, there is a history of tremors trembling these areas.
On August 23, 2011, Virginia was struck by an earthquake whose epicenter, in Louisa County, was 38 miles from Richmond and 84 miles from Washington, D.C.
Earthquake strength is measured by magnitude (Richter scale) or the amount of energy released and by intensity (Modified Mercalli scale) or the amount of damage caused.
The Virginia quake had a magnitude of 5.8 and an intensity of VII (very strong). The earthquake was felt as far south as Atlanta and as far north as Quebec, Canada. For comparison, the infamous San Francisco quake of 1906 had an estimated magnitude of 7.9. State officials estimate the Virginia quake caused over $70 million of property damage in Louisa County.
The Virginia earthquake was not a unique event. The eastern and central United States have a history of devastating quakes. The New Madrid earthquakes of 1811 and 1812, which struck Arkansas and Missouri, are the strongest to hit anywhere in the United States in recorded history. These quakes are estimated to have had magnitudes of 7.0 and 8.1. They were so powerful they created temporary waterfalls on the Mississippi River and rang church bells in Boston.
Residents in all parts of the United States should plan for earthquakes and the first step is to be aware. To understand your earthquake risk, consult the Federal Emergency Management Agency (FEMA) maps. These maps classify the U.S. into seismic design category zones. First Nonprofit recommends that nonprofits in areas with known earthquake exposures (seismic design categories B through E) develop formal earthquake instructions for their staff and clients to follow during an earthquake.
In an earthquake, FEMA recommends these key practices:
- Follow the DROP, COVER, and HOLD ON procedure. DROP to the ground. Take COVER by getting under a sturdy table or other piece of furniture. HOLD ON until the shaking stops.
- Stay away from glass, windows, outside doors and walls, and anything that could fall, such as lighting fixtures or furniture.
- Stay inside until the shaking stops and it is safe to go outside.
