WILLIS, Texas (AP) — Officials say an explosion that destroyed a house in Central Texas resonated for miles, and yet three occupants survived the blast.

The Montgomery County Sheriff’s Office says the fiery blast happened before dawn Tuesday at a home near Willis, about 40 miles north of Houston.

Montgomery County Fire Marshal Jimmy Williams says it could be weeks before investigators determine the cause of the explosion that was felt several miles away.

Williams says two men and a woman suffered severe burns and were transported to a hospital. Their names and details on their conditions have not been released.

Williams says investigators are trying to determine if any nearby homes have been damaged.
