The one in West, TX in 2013 had 240 tons of fertilizer....

...because the actual site of the explosion is off the upper right corner of the image.
Not all the available news shots were top quality, but, I'll try to find one or two that tell the actual story.
BTW, 240 tons seems off by a factor of ten (10). The main AN bin held 20 tons, and there was an open bin in a shed that held a ton or two. In the wiki photo, you can see scouring where that bin exploded. My analysis (vertically-sheared rails, etc.) indicates that there probably also was a loaded semi parked atop the rail spur, over the input dump hopper -- but, no one in West will admit that was so.
I discovered that much of my West (TX) work was on a backup drive that now won't spin up -- so, I'm creating a few new graphics on my analysis of the West AN explosion.
So -- there is a bit of "stuff" for you to loo ok forward to...
Later..
