State's largest seismograph logs Yellowstone earthquakes


BUTTE, Mont. - Scientists at Montana Tech have been busy for the last few days after a series of earthquakes shook Yellowstone National Park.

The state's largest seismograph, a device used for analyzing earthquakes, is located at Tech.

The largest quake, recorded Thursday night, registered a 4.5 on the Richter Scale.

Mike Stickney, the earthquake studies director for the Montana Bureau of Mines and Geology, says southwest Montana hasn't had a destructive earthquake in five decades.

His job as director is to run the Montana Regional Seismic Network, a network of 40 stations scattered throughout the state.

Stickney says seismic signals throughout Montana get sent back to him so he can analyze how and why earthquakes occur.

"The current activity is a reminder that we live in a seismically active area, and even though we haven't had a big earthquake lately it could occur again at any time," Stickney said.

In case of an earthquake he reminds people to stay away from objects that might fall, and keep your head covered.
