Geology
Earthquakes in Maryland are infrequent and small due to the state's distance from seismic/earthquake zones. The
M5.8
Virginia earthquake in 2011 was felt moderately throughout Maryland. Buildings in the state are not well-designed for earthquakes and can suffer damage easily.
Maryland has no natural lakes, mostly due to the lack of glacial history in the area. All lakes in the state today were constructed, mostly via dams.
Buckel's Bog is believed by geologists to have been a remnant of a former natural lake.
Maryland has shale formations containing natural gas, where fracking is theoretically possible.
