(REUTERS) - A 5.8-magnitude earthquake hit western Montana early on Thursday (July 6), the United States Geological Survey (USGS) reported, and people felt the tremor hundreds of miles away.
The earthquake struck five miles (8km) south-east of Lincoln, Montana, at about 12.30am local time, the USGS said on its website. "New experience: woken up by an earthquake. No damage just spooky as heck!" tweeted Mr Cole Fawcett in Crowsnest Pass, Alberta, about 460km north of Lincoln.
Residents in western US flooded Twitter early on Thursday with similar experiences.
"My mum woke up and yelled at me and my dad that there was a bear shaking our trailer," Mr Brad Wynder said on Twitter.
No significant damage or injuries were reported about an hour after the quake.
More than 10,000 reports from those who felt shaking were collected on the USGS website.
Several aftershocks with magnitudes of more than 4 were reported by the USGS. The Pacific Tsunami Warning centre earlier reported the quake with a magnitude of 6.
