A gas explosion at Nashville’s Gaylord Opryland Resort and Convention Center last Tuesday caused $750,000 in damages and forced more than 5,000 guests to evacuate for seven hours, the Washington Post reports.

Investigators have determined that the explosion was caused by a gas leak in a mechanical room next to the convention center, which is located away from guest rooms. No one was injured and everyone was able to return the next morning.

The blast caused serious damage to an escalator, walls, and ceilings. The hotel, which is next door to the Grand Ole Opry House, says any suspicious activity has been ruled out.
