Underwater landslide could have been cause of magnitude 4.7 earthquake reported off coast of Ocean City

January 16 2019

The U.S. Geological Survey reported a 4.7 earthquake 136 miles off the coast of Ocean City early Tuesday night.

 

The quake hit around 6:30 p.m., and occurred just over 6 miles deep.

 

State geologists said Wednesday that they believe an underwater landslide or “reactivation” of an ancient fault might have triggered it, but that they had not confirmed the cause.

 

A firefighter in Ocean City said he had not felt any tremors or related calls for service Tuesday. But dozens of people reported feeling the earthquake to the USGS. The responses came from locations across the East Coast, including Ocean City; Berlin; Dewey Beach, Del.; Norfolk, Va.; the Outer Banks in North Carolina; and even as far away as Massachusetts.

 

Several people in the Baltimore area reported feeling the earthquake as well. Overall, the reports recorded a low level of intensity.

 

In a Facebook post, Ocean City town officials said emergency officials were monitoring the situation but had not observed any effects from the quake.

 

No tsunami warning has been issued.

 

Earthquakes are relatively rare in this area. The last time the Baltimore region experienced an earthquake was in November 2017, when a magnitude 4 quake centered in Dover, Del., was felt by many across Baltimore.

"The North Anna Dam, also owned by Dominion Virginia, was reportedly not damaged, though information on its ability to withstand a large quake is not publicly available. In January 2012, the site made headlines again when a reactor was shut down to repair a non-radioactive steam leak. The two nuclear reactors at North Anna are built to withstand an earthquake at a magnitude between 5.9-6.1."

"Soon after the earthquake, the Twitter feed of nuclear industry critic Rep. Ed Markey (D-Mass.) shot out a message saying, “[E]picenter 15 miles from North Anna reactor: lost electricity, diesel working. Lessons to all nukes to check emerg power.”

 

Social media also filled with links to a March report from MSNBC that ranked North Anna the nation’s No. 7 nuclear plant at risk of an earthquake causing core damage.

 

Other plants declaring unusual events on Tuesday were Peach Bottom, Three Mile Island, Susquehanna and Limerick in Pennsylvania; Salem, Hope Creek and Oyster Creek in New Jersey; Calvert Cliffs in Maryland; Surry in Virginia; Shearon Harris in North Carolina; and D.C. Cook and Palisades in Michigan. All those plants continued to operate while personnel examined their sites."
