First recorded Maryland earthquake

April 29, 2005

The earliest recorded earthquake in Maryland occurred in Annapolis, causing a 50-second tremor in the area. The April 24, 1758, quake was preceded by subterranean noises and could be felt in parts of Pennsylvania.

There is no written record of its magnitude.

The next earthquake recorded in Annapolis was in 1876, when another slight tremor shook the city.

The most recent quake to shake Annapolis occurred this year on the morning of Feb. 23, when a minor tremor originated about 10 miles northeast of the city in the middle of the Chesapeake Bay. The quake had a magnitude of about 2 on the Richter scale.
