A magnitude 6.5 earthquake rocked western Montana on Tuesday afternoon.

The earthquake originated about 44 miles west of Challis, Idaho at around 5:52 p.m., according to the U.S. Geological Survey.

It was recorded at a depth of just over six miles.

Reports indicate the earthquake was felt as far as Spokane to areas of western Montana, including Missoula, Corvallis, Kalispell and Hamilton.

The earthquake was centered in remote, mountainous areas of Idaho, but could be felt in Boise and in other areas of the state.

There were no immediate reports of injuries, but residents on social media in several cities reported feeling the shaking.

The USGS says the epicenter of the quake was nearly 45 miles west of the town of Challis and near Beaver Creek along the Salmon River Mountains.

"Yep we felt it too. No reports of damage at this time," Boise Police Department tweeted. "Stay safe out there Boise. Call us if you need us."

Shortly after in the same area, a 4.6 magnitude earthquake aftershock was reported, according to the National Weather Service.

"We have not received any reports of injury or significant damage," Valley County Sheriff's Office posted on Facebook. "We suggest you check your propane tanks!!"

Tuesday's earthquake marked the largest in Idaho since the Borah Peak earthquake of 1983.
