A 5.8-magnitude earthquake struck in western Montana early Thursday morning, waking people up more than 30 miles from its epicenter, and felt as far away as Spokane, Washington. The magnitude 5.8 quake occurred just 12:29 a.m. MDT (local time), about 6 miles (10 km) southeast of Lincoln, Montana, according to the U.S. Geological Survey (USGS). CBS Missoula affiliate KPAX-TV reported no immediate reports of injuries, but said 9-1-1 call centers were swamped with calls and advising people to only call if they were injured. KMVT-TV in Twin Falls, Idaho reports power outages around the earthquake’s epicenter.

Earthquakes do occur periodically in Montana, but this one was a relatively strong one – therefore rare – for the region.

Did you feel it? Tell USGS

USGS also provided this background:

Western Montana and northwestern Wyoming have experienced at least 16 other M 5+ earthquakes within 300 km of the July 6, 2017 event over the preceding century. The largest was the August 1959 M 7.2 Hebgen Lake earthquake – the largest historic event in the intermountain region – which occurred about 280 km to the south-southeast of the July 6 event. The Hebgen Lake earthquake triggered a large landslide that resulted in significant damage and more than 28 fatalities. A M 6.9 earthquake just over 100 km to the southeast of the July 6th earthquake in June, 1925, caused significant damage, but no fatalities. A M 5.6 earthquake occurred 170 km to the south of the July 6th event in July 2005, and caused minor damage in the surrounding region.

Bottom line: The 5.8-magnitude earthquake in western Montana on Thursday, July 6, 2017, is expected to be followed by aftershocks.
