Geologist Michael Stickney said were reports of Butte residents feeling Tuesday’s earthquakes, while some people in Lima described them as a bomb or an explosion, KTWQ reports.
One of Tuesday’s earthquakes occurred along a fairly active fault called the Centennial Tectonic Belt, Stickney said.
This fault hasn’t experienced a major quake in decades.
"The really significant earthquake that occurred in this zone was the 1983 Borah Peak Idaho earthquake, which had a magnitude of 6.9. It resulted in two fatalities in Challis and caused significant damage," Stickney said.
