4.2-Magnitude Earthquake Shakes Central Idaho, Felt in Boise

CLAYTON, Idaho — A 4.2-magnitude earthquake struck central Idaho on Monday morning, sending tremors as far as Boise, according to the United States Geological Survey (USGS). The quake occurred at 9:32 a.m. local time, 26 kilometers west-northwest of Clayton, near the Challis National Forest, with a depth of 11.4 kilometers.

Residents across the region reported feeling the ground shake, particularly in Boise, where several individuals commented on the unexpected tremors. The USGS confirmed the earthquake’s magnitude and location, noting that it was a relatively shallow event.

“Earthquakes of this magnitude are uncommon in this area but not unheard of,” said a USGS spokesperson. “We encourage residents to report any additional tremors or damage to help us better understand the event.”

No injuries or significant damage have been reported so far. However, local authorities are assessing the situation, particularly in rural areas near the epicenter. The Challis National Forest, a popular destination for outdoor enthusiasts, remains open, but visitors are advised to exercise caution.

Idaho lies within the Intermountain Seismic Belt, a region prone to occasional seismic activity. While most earthquakes in the area are minor, Monday’s event serves as a reminder of the state’s geological vulnerability. “It’s always a good idea to be prepared,” said a local emergency management official. “Have an emergency kit ready and know how to respond during an earthquake.”

The USGS continues to monitor the area for aftershocks, which are possible in the coming days. Residents are encouraged to stay informed through official channels and report any unusual activity.
