A few minutes after 10 o'clock Sunday night, folks in the Seeley Lake area felt the earth move twice with a magnitude 3.7 earthquake,  preceded just 25 seconds before by a smaller quake with a magnitude of 3.1 on the Richter Scale. The quake was felt as far away as Ovando, Ronan and even Helena.

Mike Stickney, Director of Earthquake Research at the Montana Bureau of Mines and Geology in Butte says the earthquakes caused no damage because the epicenter was so deep in the mountains around Seeley Lake. Stickney says the double earthquake was unusual but not necessarily rare. Stickney says the Sunday night quakes are two more in a series that are common in the Southern Swan range, and the strongest in recent years measured at 4.2.
