A massive earthquake has rocked at least four US states on a national holiday weekend.
The earthquake measured 5.8 on the Richter scale.
People were just waking up for Labour Day weekend when the quake struck.
Shocked sleepy-eyed Twitter users were quick to mention the earthquake online.
The earthquake was felt by a huge number of people throughout central US.
Twitter users said they could feel the shaking as far away as Chicago which is 800 miles away.
In February there was a 5.1 earthquake measured in Oklahoma, the third largest ever felt in Kansas City.
Experts have predicted that a massive worldwide earthquake is coming.
