Here is an article I came across on Twitter about the Montana earthquake:  Montana Earthquake Is Felt For Hundreds Of Miles Early Thursday Facebook Twitter Google+ Email July 6, 20177:13 AM ET

An earthquake with a magnitude of 5.8 startled many people out of their sleep in western Montana early Thursday. The shallow quake was felt for hundreds of miles from its epicenter southeast of Lincoln, including in parts of neighboring states and in Canada.

"We have no reports of injuries due to the earthquake at this time," member station Montana Public Radio reports. "Shockwaves are still being felt with decreasing intensity in parts of western Montana."

Thursday's earthquake was the strongest to hit western Montana in years; it was slightly stronger than a 5.6 magnitude quake that hit a nearby area in July 2005, the U.S. Geological Survey says.

Some alarmed residents said via Twitter that they woke to fears that an intruder was in their house; others said their dogs had seemed to sense the oncoming quake — and jumped on their owners to seek safety.

The dog knew it was coming. He started barking and jumped off the bed. Then the house started shaking.

"It was strong enough to wake people up across a wide area, and was felt along a line more than 500 miles long, from Billings to Spokane, Wash.," Montana Public Radio's Eric Whitney reports for our Newscast unit.

Residents reported waking to the sound of pans clattering around and the feeling of their houses being shaken.
"Woke me and my parakeet up," Terry MacPheat wrote on the MTPR Facebook posting about the quake, adding, "bed was shaking like something from an Exorcist movie!"

And let me just say a huge thanks to @Twitter for existing so I could confirm I wasn't crazy when I felt that damn #earthquake #Montana

Another MTPR listener, David Buckingham, reported, "I was awake here in Bozeman, sitting at my desk, when it happened; it felt like I was on a boat in choppy seas, and all the birds in my neighborhood simultaneously made a ruckus and flew away."

Aaron Birkholz, who runs a roadside coffee stand — where a sign was touting "huckleberry shakes" Thursday — also compared the experience to being on a boat, telling MTPR's Whitney that it had given him motion sickness.

"This one was different, it wasn't a real quick shake," Birkholz said of the earthquake.
