I did see somewhere mention that nearby was a grain silo as well, and grain silo’s explode quite well. I don’t think I’ve ever seen one quite that size though.
In regards to the BLEVE, they usually take quite a while to happen as you have to wait for the gas to boil and then the pressure to build to the point that the container explodes from the pressure. Not sure how long between the first and second explosions, as I’ve not looked in to it that much. I’d also expect multiple bangs if it was multiple LPG canisters, rather than that huge explosion.
However, that first fire could have ruptured them and then a huge explosion as they gas ignites – think Buncefield, as that was one of the largest peace time explosions in Europe.
