What causes earthquakes in Maine

BANGOR DAILY NEWS • January 27, 2025

Since 1997, there have been more than 150 recorded earthquakes in Maine. Those tend to be weak movers and shakers ranging from magnitude 0.7 to 2.8. You may not even feel many of those. What causes earthquakes here isn’t well understood. It may be stress released along zones of weakness. Maine State Geologist Ryan Gordon said that the movement of tectonic plates may be causing cracking and the occasional rumbling we feel. Or it could be the ground rebounding from the last ice age. But, without a doubt, there aren’t any active faults near Maine.
