This person has interesting comments,,,says “When HMX is heated, it undergoes deflagration, emitting brown smoke.
He says it was an arms depot, missiles from Iran, that were intentionally destroyed...not an accident. Has 3 different posts about it,,,here’s a link to the first one:

I won’t argue w any of that, except the still image he has labelled “A second explosion” is lens flare and reflected light from the first few milliseconds of the main detonation. I managed to capture that one myself, a coupla times, freeze-framing thru various videos.
And, I still think the big one originated in that southern warehouse. Key location references to keep track of thru various videos,are the silos (note orientation) and the crane farm, far east side of southern warehouse.
.FWIW... last vid I watched seems to have... harbor... where that southern warehouse used to be.
