M 5.8 earthquake hits Lincoln, Montana

July 6, 2017: An earthquake measuring 5.8 in magnitude hit just after midnight about 6 miles southeast of Lincoln, Montana.

The earthquake occurred at 12:30 am at a shallow depth of 13km.

The tremor was felt as far away as Bozeman, Idaho, and Great Falls. The earthquake was followed by several smaller aftershocks.

According to the USGS, the earthquake occurred as the result of shallow strike slip faulting along either a right-lateral, near vertical fault trending east-southeast, or on a left-lateral vertical fault striking north-northeast. 

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.
