This video is a few months old and has been shown more than a few times but we wanted your thoughts. What happens to cause this fire to vent violently? If you notice the fire seems to really build a substantial amount of energy as the video rolls forward and fire ground operations sound firmly in hand. You can hear command speaking via the radio with fire fighters. Then the fire seems to lose energy right before the violent release of flames. You can hear command classify it as an explosion butÂ was it really?

Here are a few sequential pictures showing the fire as the video starts, then a few seconds before the event and finally at the time of the event itself. Compare the smoke and fire yourself.
