A house exploded in Plum, Allegheny County, on Saturday morning, causing multiple homes on Rustic Ridge Drive and Brookside Drive to catch on fire.

The house which exploded was completely leveled as a result of the flames. Debris could be found nearly 100 yards from the site of the explosion. The sound of the explosion was so loud that it could be heard at a local baseball game.

The initial call for the explosion came in just before 10:30 a.m. local time. Thirty first responder vehicles responded to the scene, from areas including Murrysville and Monroeville. Multiple gas companies were also on the scene. 

A video from the scene showed black smoke billowing into the sky. The home which exploded belonged to borough manager Mike Thomas, Plum Mayor Harry Schlegel told Pittsburgh’s Action News 4. Thomas, his wife and daughter are reportedly in the hospital. There is no information on their conditions.

A neighboring home which also caught fire after the explosion also led to the hospitalization of a member of the family who lived there. According to Schlegel, the entire housing plan was being evacuated.

This is a developing story.
