What gave rise to the BLEVE at the site. Was it a tank of oil or chemicals?
There was a fire next to a 25,000 gallon fuel tank which vented and added to the fire. The fire department got on site and started attacking the fire and also tried to get water on the tank. All of a sudden the tank vented a big exp0anding gas ball and a fuel/air explosion occurred sending flames in front of it for a city block in the blink of an eye.
A bigger version may have been part of the Pepcon rocket fuel plant explosion in Nevada — see this:

A film crew happened to be filming on a mountain top nearby and captured the double whammy.
