(WVLT) - Dozens of people in Knox County woke up to some rumbling this morning and investigators are still working to figure out what it was.
Dozens of calls flooded central dispatch at about 1:15am, mostly from two neighborhoods off Northshore Drive in West Knoxville; Admiral's Landing and Northshore Landing.
Many people tell us they woke up to loud rumbling and thought there were animals or prowlers in their basements or attics.
Others thought there was some sort of explosion shaking the ground.
J.R. Andrews lives in Admiral's Landing and says it woke his entire family up and they all ran outside to see what was going on.
"Half of our neighborhood had come outside and there was these constant shakes in the ground, constant thud. It felt like some type of missile attack," he said. "It wasn't an earthquake, I've been through an earthquake."
KUB not reporting any problems in the area and so far, there has been no reports of a possible earthquake.
