North shot looking South. In the lower left, it appears to be the ROOF of the tank from the large concrete pad, laying on its top. The whitish, clean looking area, just above the concrete pad (just SOUTH of the pad) looks to be the initial spot of the explosion. That would have been inside the large storage building. We can see the charred remains of the office building to the left. That is what seemed to be on fire BEFORE the explosion.
Last one for the night. EAST side shot. Office building that was burning in the foreground. The Dry Fertilizer storage was above that. That is the center of the explosion. Above that, we can see the very damaged apartment complex. To the left we can see the chemical storage tanks and the ammonia storage tanks. To the right we can see what we think were the grain storage tanks that were blown off their pedestal. Looks like you were right Navy.
