A video has emerged capturing the devastating home explosion in Evansville, Indiana, as authorities Thursday are searching for answers as to what caused the blast that left 3 dead and dozens of properties damaged. 

Evansville Fire Department Chief Mike Connelly said a total of 39 houses were damaged by the explosion at around 1 p.m. Wednesday, 11 of which are now "uninhabitable," according to the Evansville Courier & Press.  

The surveillance footage captured by a local resident shows smoke and debris raining down from the sky following the massive explosion.

David Anson, chief deputy coroner for Vanderburgh County, told The Associated Press that the identities of the three people who died would not be released until the next of kin has been notified.

Evansville Police Department spokeswoman Sgt. Anna Gray said at least one other injury was reported, and that victim was taken to a local hospital for treatment. 

Connolly also said the fire department has not confirmed how many of the houses were occupied when the explosion happened because "some were too unstable to enter." 

The blast, he said, left debris strewn "over a 100-foot radius," including "typical construction materials" such as wooden boards, window glass and insulation.
