Magnitude 2.3 Quake Felt Near Maine–Canada Border With No Damage Reported

State geologists say the tremor fits Maine's pattern of small, shallow earthquakes.

Overview

USGS confirmed a magnitude 2.3 earthquake at 6:55 p.m. Monday near Bridgewater in Aroostook County at a depth of about 3.1 miles.
Dozens reported weak to light shaking with no damage, including residents in Bridgewater, Monticello, Westfield and Presque Isle.
Northern Maine quakes are uncommon, with at least 19 recorded in Aroostook County since 1990 and this being the first non-microquake there since 2019.
University of Maine at Presque Isle geologist Chunzeng Wang believes the event occurred along the Hammond Fault near Packard Lake on the Canadian border.
Maine has logged more than 170 earthquakes since 1997, with occasional clusters such as York Harbor in early 2024 and Jonesboro in 2022, and a magnitude 3.8 off York Harbor in January 2025 among the strongest in recent records.
