A light, 4.2-magnitude earthquake struck in Montana on Thursday, according to the United States Geological Survey.
The temblor happened at 12:41 p.m. Mountain time about 7 miles northeast of Malmstrom Air Force Base, Mont., data from the agency shows.
As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.
