Fertilizer plants are essentially low-grade munitions factories. Bit like a firecracker store ticking off.
Based on the pics, the explosion cloud quite literally looks like a 1-5 kiloton tacnuke.
I have stopped at the Czech Stop Bakery many times. Best gingerbread men ever.
This explosion was felt 60 miles away.
Triage area had to be evacuated.
Expecting a storm tonight on top of all of the devastation.
Fertilizer in and of itself (Even AN or urea)is not explosive.
