(LIBBY)- Another small earthquake shakes Northwest Montana, the second time in less than a month that the Libby area has felt the earth move.
The US Geological Survey reports the magnitude 3.5 quake hit just before 7 o'clock Tuesday evening. Preliminary indications were that the quake's epicenter was 27-miles southeast of Libby, 39-miles west of Kalispell. That would put it close to Happy's Inn and not far from the Thompson Lakes.
The quake was quite shallow, just over 1-mile below the surface.
That puts it in the same general area as a 2.5 quake that happened on May 3rd.
