A disturbing video has surfaced depicting a sudden house explosion.

The tragic event in Pennsylvania claimed the lives of five individuals, among them Casey Clontz, 38, and his son Keegan, aged 12. The police have yet to identify the other three adult victims.

Additionally, another individual is critically wounded from the blast, and 57 firefighters sustained injuries while responding to the incident.

A doorbell camera recorded the serene neighborhood being jolted by the massive blast, powerful enough to jostle the porch and topple a sign even from a distance.

It's reported that Keegan and Casey were near the residence when the explosion occurred. Their family has since commemorated them, reflecting on their tragic, premature passing.

The family shared: "Keegan and Casey were their most happy when they were spending time at the lake with their lake family and friends. They swam, did boating and loved cruising around in their golf cart.

"Keegan and Casey will be missed by so many and will continue to be loved by so many including their family, friends, and community."

Post-explosion images reveal the extensive destruction of the home. An inquiry has been initiated to pinpoint the explosion's cause.

Peoples Gas, the utility supplying gas to the residence, is currently examining the event's origins and has verified its team's presence at the explosion site within a quarter hour.

Peoples Gas President, Mike Huwar, informed WTAE: "We immediately began checks in the area for leakages, including smell checks and testing for gas underground and in the air.

"We also verified consistent pressure at tour regulation stations. At this point we can share that our system was operating as designed."

Josh Shapiro, Governor of Pennsylvania wrote: "Lori and I are praying for family, friends, and neighbors who lost someone in Plum yesterday, and we're grateful for the first responders who ran towards danger to save lives. The five Pennsylvanians who passed and their families are in our thoughts today. May their memories be a blessing."

Officials from Allegheny County mentioned that the probe into the explosion's origin might span several months.

The explosion occurred roughly at 10:30 am on August 12, resulting in the destruction of at least two adjacent homes and damage to approximately twelve others.

Nearby resident, Justin Newman, informed WTAE: "We need to know why this is happening. It's sad that people lost their lives and we don't have answers. We need answers for these families, we need answers for this community."
