Crews are investigating a house explosion in Geauga County Thursday evening.

The explosion occurred at a home on Penniman Drive in Hambden Township around 9:00 p.m.

Fire officials say two children and one adult were inside the house when the explosion took place. Authorities say they have all been treated and released from the hospital, but the home is expected to be a total loss.

A neighbor apparently heard the explosion and called 911. Officials say it only took fire crews 30 minutes to get the fire under control as departments from several neighboring communities assisted.

Portions of the second floor, near the area where the home sustained significant damage, appeared to settle some as workers tended to the house.

There is no word on a cause of the explosion. Geauga County's Fire investigation Unit responded to the scene and is now investigating.

On Friday, Dominion Energy reported that they found no leaks in the company's main or service lines to the house and emphasizd that their facilities did not contribute to the explosion.
