Investigators returned to the scene of a deadly natural gas explosion in rural Johnson County this morning to determine its cause.
The spectacular 2:45 p.m. explosion, along a gas line midway between Cleburne and Granbury on Georges Creek Ranch, killed one person, rocked homes miles away and shot flames into the air that could be seen just outside Fort Worth, about 30 miles to the north.
This morning, utility workers checked power lines at a nearby electrical substation, while the owners of the property bisected by the 36-inch-line surveyed the charred scene, where the the smell of smoke still hung heavy..
Johnson County officials said the rupture, which occurred about 2:45 p.m. Monday, was caused by a work crew using heavy-duty digging equipment in the area.
The Texas Railroad Commission will lead the investigation into the explosion. Officials with the Occupational Safety and Health Administration and the National Transportation Safety Board will also look into it.
The explosion seared acres of prairie and could be felt more than five miles away.
"My whole building was shaking," said Carolyn Black, who lives about five miles away from the explosion site. "It sounded like someone landing a big Jumbo 747 in the backyard."
"It was a digger that digs a hole for a power pole," said Cleburne Fire Chief Clint Ishmael. "It's an auger for a high-transmission power line, and that's what they were working on, and they drilled into a 36-inch high-pressure natural gas line.
"Something went terribly wrong."
