At 8:07 p.m. on Monday, October 2, a minor earthquake of magnitude 3.8 shook the ground around Acadia National Park. The epicenter of the earthquake was located in the Atlantic Ocean just off Great Head, on the eastern side of the park. Damage appeared to be limited to rocks falling on the Park Loop Road, which re-opened on Tuesday afternoon after a brief closure, and on some park trails (see Temporary Closures for a list of closed trails).
This earthquake followed several small aftershocks that have occurred since the first earthquake on September 22 (magnitude 3.4). The epicenter for the September 22 earthquake was located in the park, just off the Precipice Trail parking area on the Park Loop Road. No damage was reported.
According to the Maine Geological Survey, earthquakes in Maine are rare, with just 507 earthquakes occurring in the state from 1747 to 1992. During that time, only one other earthquake originated from Mount Desert Island. Most earthquakes that do occur in Maine are minor, and to date none have caused significant damage.
