What a horrible thing to happen to Lebanon. I heard on the news that 2700 tons of ammonia nitrate went up. To put this in perspective, the Oklahoma City bombing used 2 tons of ammonia nitrate...

This explosion registered 3.85 on the Richter scale and was heard and felt in Cyprus, 180 miles away. Damn, just damn.

My heart goes out to the people of Beirut, may the good Lord help them through this tragedy. Regardless of your religious affiliation, you might slip in a prayer for these folks.

Personal aside, years ago, as a young man I worked in refractory construction and the firm I worked for did a turnaround at an ammonia nitrate plant in eastern Oklahoma. I reported to the plant engineer and on the wall of his office, there was an aerial photograph of the plant flattened. I asked him what happened. He said years prior during the night shift the plant exploded, 4 men were killed and all the windows in the nearest town, 7 miles away were shattered and it rocked the buildings in downtown Tulsa. I asked how much product detonated and he said "Ten tons". I asked how much product did they have on hand at the time, his response was "100,000 tons." I said "I will be done with what I have to do in 24 hours or less". I had been in a refinery when it caught on fire and wasn't all that worried then, but working in that plant spooked me and I got into something else.

 
That explosion was just mind boggling ... the damage is just shocking ... like a mini nuke went off.

The casualty figures likely to be quite bleak once they sift through all the rubble and wreckage. :oops:

Yep, so far I have heard 100 fatalities and 4000 wounded, but it's going to go higher. Anyone close to that blast are now molecules. It's just horrific.
 
Oh, my.

Whilst the explosion was mighty, the shock wave that followed really was bloody staggering!!!

Here's hoping that both lives and property can be rebuilt as quickly and safely as possible.
 
The information that I've seen suggests it was bags of ammonium nitrate prill, ie ammonium nitrate in pellet form.

Ammonium nitrate is an accelerant, not an explosive in and of itself, it will basically magnify any explosion it finds itself a part of, and given that this was a fireworks factory that went up, well, you get the idea.

Ammonium nitrate is also commonly used in mining, it is mixed with diesel at which point it becomes ANFO (ammonium nitrate fuel oil), I'm sure you've all seen a mining charge go off before, it's quite impressive to say the least.

We can be grateful that it wasn't 2700 tons of ANFO going off, if so, it's likely the entirety of Beirut would be a giant crater.
 
Those grain silos prevented damage and loss of life on the other side of them.
Oh. Thank heavens those were grain silos. I was thinking downtown Oklahoma City Murrow building. That detonation was big, but this one dwarfs it. That crater is enormous. Has anyone seen a link to a size comparison of the two?

EDIT: "2,750 tons of ammonium nitrate. For context, the Oklahoma City bombers used 2"
 
My family is from Lebanon and so I am hearing a lot about this.

Yes--that grain silo did an amazing job of stopping the blast. Things could have been much worse.

I want to understand how the fire started in the first place. All I hear is speculation.
 
When they start thinking about rebuilding someone ought to call the guys that build the grain silos.

I think grain silos are designed with explosions in mind since crop dust can be explosive. They are also heavy duty to hold all that heavy grain. The grain itself is also a form of "armor."

Still.....it is amazing that the silos are still there.
