VIDEO: Since June 1, there have been over 35 earthquakes in the Stanley area, with the last two striking Tuesday morning. The epicenters were about nine to ten miles northwest of Stanley, but this area is no stranger to earthquake swarms. There have been over 20 earthquakes over a magnitude of 2.0 since Saturday according to the United States Geological Survey. Earthquakes under magnitude 3.0 are generally not felt by people. According to Christopher DuRoss, a research geologist with the USGS, these recent quakes, as well as others felt in Stanley, are all lingering aftershocks from a 6.5 magnitude earthquake that hit the Stanley area and caused damage in 2020.
โThese aftershocks can occur for years, weeks, to months following the main shock earthquake, and they gradually decrease in both frequency and magnitude over time, but again, that can continue for years,โ DuRoss told KMVT. DuRoss adds that since March 2020, the USGS has reported around 6,500 of these aftershocks in the Stanley area. The Borah Peak Earthquake, a bit farther east in the central mountains, on Oct. 28, 1983, was a magnitude 6.9 and the largest recorded earthquake in Idaho.
