Update, 5:30p.m.: Maryland Gov. Martin O'Malley (D) has released a statement on this afternoon's quake.
“The earthquake this afternoon was an extremely unusual occurrence for us here on the East Coast. I have been briefed by members of my cabinet and public safety officials on the status of state facilities and operations. Presently, there are no reports of significant damage or incidents and we will continue to monitor the situation closely, particularly over the next 24 to 48 hours. We will be paying close attention to our utilities for problems with water mains or gas lines that may not be present immediately following an earthquake.
“Of course, when the earthquake first hit, our thoughts immediately turned to the safety of our loved ones. I encourage everyone to check on their family members, friends and neighbors; particularly the elderly to make sure everyone is safe.”
Residents should be advised there may be more tremors, in addition to the 2.8 magnitude aftershock the USGS reported at 2:46 pm.
Mike Blanpied, USGS associate coordinator for the earthquake hazards program, said there could be more aftershocks and they could go up to 5 in magnitude. “Aftershocks could go on for days, weeks, or even months. They’re most likely to be felt under the next three or four days,” Blanpied said, as reported by the Washington Post.
The aftershocks are generally, but not always, of a lesser degree than the original earthquake, according to Thomas Jordan, director of the Southern California Earthquake Center, as reported by sussexcountian.com
Jordan recommended removing any heavy or breakable objects that could fall and injure someone.
“A lot of people are injured by stuff falling, so make sure that big rock you picked up on vacation isn’t sitting on a shelf,” he said. “The chances of getting large shakes are small, but my advice would be to do now what you should be doing all along.”
Update, 4:30p.m.: Earthquake FAQ's are now available via Montgomery County Fire and Rescue.
This is Metropolitan Washington’s second quake in just over a year. A 3.6-magnitude tremor—less than one-tenth the strength of today’s quake—struck five kilometers beneath Gaithersburg last July.
Maryland’s earthquake history dates back to a 30-second quake reported in Annapolis in 1758.
USGS archives list no "significant"—magnitude 3.5 or greater—Maryland-based seismic events since an 1885 quake near the Frederick County-Loudoun County border. Reports over the last few decades have come from earthquakes in neighboring states, including:
- A 4.3-magnitude earthquake near Elgood, W. Va. in 1969
- A 1972 tremor centered in Wilmington, Del.
- A minor earthquake near the Delaware-New Jersey-Pennsylvania border in 1973
- A 4.5-magnitude quake west of Richmond, Va. in 2003
