Montana hit by strongest earthquake in more than half a century

A magnitude-5.8 earthquake hit western Montana early this morning, the U.S. Geological Survey reported. Related to Yellowstone? Perhaps not.

The earthquake struck five miles (9 km) southeast of Lincoln, Montana, the USGS said on its website.

It was “the strongest earthquake to hit Montana in more than half a century,” The Spokesman-Review reported.

People felt the tremor hundreds of miles away, from Spokane to Billings and parts of other neighboring states, even into Canada. 

Several aftershocks with more than 4.0 magnitudes were reported by the USGS.

Mike Stickney, seismologist at the Earthquake Studies Office, Montana Bureau of Mines and Geology on the Montana Tech campus in Butte, said the quake was probably the strongest in Montana since October 1964.

Connected to Yellowstone supervolcano?

The quake’s epicenter was located some 230 miles from Yellowstone National Park, leading some to wonder if it was connected to the Yellowstone supervolcano.

The recent swarm of 1,100 earthquakes at Yellowstone added to the wonder.

However, Stickney said he “does not believe” the quake is seismically tied to the recent “swarm” of smaller earthquakes in the Yellowstone National Park area.

The Yellowstone Volcano Observatory’s most recent volcano alert level is listed as normal, dampening fears of a supervolcanic eruption.

  1. I check the YMR seismometer regularly and the 5.8 quake was an attention getter. The thing is the YMR seismometer is sensitive enough to detect quakes at a considerable distance from Yellowstone especially the larger quakes with a magnitude 4 or better. Its sensitivity rating is 125 microvolts and is one of the most sensitive in the park. Except for one other the rest are far less sensitive in order to filter out the micro quakes and back ground noise.

  2. …yeah, right not related to Yellowstone!! Kinda like the Sun has no effect on Earth’s weather! Please refer to your encyclopedia on the word ignorance. To ignore is to not know; or not want to know. They are ignorant of the obvious!

  3. I hope we are not going to be allive at the time Yellow stone goes off.

    Goodbye USA if it does.

    The USA has the madrid fault and the CSZ likely to happen in the next 20 years due to the solar minimum and I found John casey’s Upheaval book compelling and well researched.
