Tuesday night's massive explosion at a fertilizer plant in West, Texas was recorded by the U.S. Geological Survey as a 2.1-magnitude earthquake at 7:50 p.m.
That shock wave was felt as far away as North Texas.
"I live in Groesbeck," wrote Rayne Sibley on WFAA's Facebook page. "I heard a large boom and my house shook."
Facebook users in Venus, Grandview, Cleburne, Ennis and Ferris also reported feeling the shock wave.
"Shook my doors!" wrote Nancy Procaccini of Combine. "Thought it was earthquake!"
"We felt it in Ennis," added Carol Walker Martin. "The concussion from it actually blew our storm door open because we had the windows open to let in the breeze."
