Wisdom, MT – A small earthquake shook parts of western Montana and the nearby Idaho border early Thursday morning, according to the U.S. Geological Survey (USGS).
The quake, measured at magnitude 3.4, struck at 2:20 a.m. UTC (Wednesday night local time), centered about 15 kilometers west of Wisdom in Beaverhead County. USGS reports place the depth at roughly 22 kilometers, making it a relatively deep event for the region.
According to USGS data, at least two residents submitted reports of feeling light shaking from the earthquake. The event was marked with an intensity level of IV on the Community Internet Intensity Map, indicating weak-to-light shaking that is unlikely to cause damage.
No damage or injuries have been reported as of Thursday morning. Earthquakes of this size are considered minor but are not uncommon in the seismically active Northern Rocky Mountains, where tectonic forces between Montana and Idaho often produce small-to-moderate quakes.
The Montana-Idaho border region, including Beaverhead County, has experienced several low-magnitude quakes in recent months. USGS encourages residents to report what they felt to help improve data collection on seismic activity in the area.
