Crews in Maryland and D.C. are inspecting bridges after Friday morning’s earthquake.

Maryland State Highway Administration spokesman David Buck said that as of late Friday morning, no damage has been found following the 3.6-magnitude temblor.

Crews in Washington are inspecting some of the older bridges and preparing a list of other locations to conduct more thorough evaluations, according to an e-mail from D.C. Department of Transportation spokeswoman Karyn LeBlanc.

A geophysicist with the U.S. Geological Survey’s National Earthquake Information Center said the quake, centered in Rockville, struck at 5:04 a.m. Friday. He said aftershocks could occur over the next couple of days. None have yet to be reported.
