So yes, quite ridiculous.

The other anomaly is the deep red smoke, that's something that seems unusual too (aside from storing so much fertilizer in such a built up area for so long). This is a disaster on so many levels, but then when is a disaster only caused by a single issue?

This is good evidence against an intentional detonation. Even if it were arson, it probably wasn't an intentional detonation. It's inconceivable that anyone with enough research to successfully cause an ammonium nitrate detonation wouldn't have run across the fact that any of a number of cheap organic fuels increase both the power and reliability of ammonium nitrate explosions. So, it's very unlikely this was an intentional explosion, unless they were trying to make it look like an accident. If they were trying to make it look like an accident, then the objective wasn't to generate fear in the populace / political change, and any conspiracy theorist then has the problem of having to figure out what the specific target was, since we can rule out the general populace. This should put most conspiracy theories to rest, at least without silly statements by the tweeter-in-chief.

Many angles here as well
