FORT WORTH (CBSDFW.COM) – Did you feel it?

An earthquake shook parts of North Texas late on Thursday night. Facebook, Twitter and the phones at CBS 11 News were flooded with people who were wondering what had just happened to the ground below their feet.

According to the National Earthquake Information Center in Denver, the earthquake hit at 11:21 p.m. Thursday and was centered in Waxahachie. It was only a magnitude 2.5 quake and damage is unlikely. But the rattling was felt by a large number of people, most in east Fort Worth – 40 miles away from the epicenter.

Geophysicists say that the energy from earthquakes travels, and it is common for them to be felt far away from where they actually originate.

“I’ve been living here for a long time in Fort Worth,” said resident Richard Simms. Both he and his wife felt the quake and called the police, not knowing what else to do at first. “I’ve heard of them in other parts of the country, but not here.”

Police dispatchers said that many people had called to report the earth moving.

And the National Earthquake Information Center said that it is actually not unusual for an earthquake to happen in North Texas. The last one – a magnitude 3.0 – occurred on July 17.
