This just popped up - video of the aftermath of the explosion.
Looks like something after a WWII firebombing raid.
Just.....damn.

That video looks like houses. I think the fuel facility that exploded is about 30 miles SE of the center of towntown based on the weather satelite video showing the blast radiating out. Seems like a fairly isolated facility, so obviously a huge blast to cause so much damage far away.
