BUTTE – Friday’s large earthquake that hit just outside of Anchorage, Alaska was picked up by seismic equipment in Butte.

Michael Stickney of Earthquake Studies Department at Montana Tech reported that the seismograph in Butte clearly recorded the quake.

Initial reports showed a magnitude 7.0 quake and a 5.8 magnitude quake, which is similar to the size of the quake that happened near Lincoln in July of 2017.

“The Lincoln earthquake was well away from populated areas — at least 20 miles from outside of Helena. Whereas the Anchorage earthquake occurred almost directly underneath the city, so they were sitting right on top of it,” Stickney said.

He added that Montana, Alaska gets many earthquakes, but often the magnitudes are larger than the ones that hit in the Treasure State.
