BUTTE – A magnitude-3.4 earthquake shook the Dillon area Wednesday morning but did not cause any damage.
Mike Stickney, earthquake studies director with the state Bureau of Mines and Geology in Butte, says the quake struck at 11:16 a.m. He says the epicenter was about eight miles north of Dillon.
That’s close to the epicenter of a magnitude-5.6 quake that severely shook Dillon in July 2005.
Stickney says that since the 2005 temblor, researchers have recorded more than 1,300 aftershocks within about three miles of that epicenter.
