(ETH) – Residents of Boise, Idaho continue to shake, rattle, and roll as a magnitude-4.1 aftershock that is directly connected to last month’s large earthquake was felt by some residents on late Monday night just before midnight according to a report from the Idaho Statesman.

The report stated that the epicenter was 20 miles northwest of Stanley and that the latest aftershock is one of eight reported aftershocks that has taken place in Idaho with a magnitude of 2.5 or higher recorded by the USGS in the past 24 hours.

Idaho residents have been rattled by aftershocks since a magnitude-6.5 earthquake struck the region on March 31. The epicenter was determined to be in the mountains northwest of Stanley and 45 miles west of Challis.

That earthquake was reportedly felt throughout the West, with reports that it stretched into Washington, Utah, and Montana and produced avalanches in the Sawtooths, as well as damage to buildings in Custer County.
