6 Jul 2017, 3:22 pm

A magnitude-5.8 earthquake hit western Montana early on Thursday, the U.S. Geological Survey reported, and people felt the tremor hundreds of miles away.

The earthquake was 13.6 kilometers (8.4 miles) in depth and was about 33 miles northwest of Helena, the capital, according to USGS. It struck about 7 miles southeast of Lincoln, which has a population of 1,013. The USGS noted seven other quakes ranging from magnitude 3.5 to 4.4 in the area over the next four hours. Three others followed, with the most recent being a magnitude 3.7 quake at 9:27 a.m.

Thursday’s quake is the strongest in the region in several years. The most recent reading of 5.8 or higher was a 5.9 magnitude quake in Nevada in 2008. A 5.6 magnitude quake in 2005 occurred 105 miles to the south of Lincoln and caused minor damage. There have been more than 70 quakes measuring larger than 4.5 in Montana and parts of Wyoming and Idaho since 1925, according to the USGS. The largest quake in Montana history was magnitude 7.2 near West Yellowstone in 1959.

There were no immediate reports of injuries or serious damage from the magnitude-5.8 earthquake that hit early Thursday.
