Western Montana and northwestern Wyoming have experienced at least 16 other Magnitude five earthquakes within the last 100 years.
The largest was the August 1959 M 7.2 Hebgen Lake earthquake – the largest historic event in the inter-mountain region – which occurred about 280 km to the south-southeast of the July 6th event. The Hebgen Lake earthquake triggered a large landslide that resulted in significant damage and more than 28 fatalities.
The U.S. Geological Survey said the quake was associated with the Lewis and Clark fault line, a zone that stretches from east to southeast from northern Idaho to east of Helena, Montana and southeast of this earthquake.
