Beirut Airport damaged by downtown explosion

Tue Aug 04, 2020 6:36 pm

You've probably seen the stories about the "something" exploding and majorly damaging the city. But apparently the airport 10km away had damage, too

Would not be surprised. It's just around the corner and not far in a direct line. I fly there often and always had a soft spot for the people and place. Such a beautiful approach. Whatever caused this I hope many are safe.

That explosion reminds me of the shuttle booster factory in Utah that blew up. Holy cow. The shock wave alone - can't imagine how many casualties.

    Amazingly lucky no aircraft was in the vicinity.

    My thoughts go out to everyone affected by this disaster. Hope that there was no foul play involved. On an aviation note, it would appear as the Beirut Airport is still operating, as Flightradar24 shows a Yan Air/Eritrean Airlines 737-300 (UR-CNF) that appears to have taken off from Beirut.

    https://www.flightradar24.com/data/aircraft/ur-cnf
    Last flown aircraft: DH8D OE-LGN < DH8D OE-LGI < E195 OE-LWE < DH8D OE-LGI < A320 D-AIUR < A320 D-AIZM < B738 PH-HZJ < B737 PH-XRD < B772 N766AN < B738 N855NN < B788 N45905 < A319 N808UA < A320 N482UA < B752 N19117

    Agree I feel the same been numerous times and shocked seeing the videos. Sadly the news reporting more deaths and injuries. It was heard in Cyprus 234KM away .

    I'm trying to understand how it could have caused that damage at the airport, which is so far away. I think this is perhaps falling debris (like a container, perhaps).

    In NonAviation is another thread with many videos. It was the shockwave. there was no debris falling from the sky. The airport is only around 10 km away, up to 25 km away, windows have been destroyed.

    Could be falling debris, too. Initial reports say that we are talking a kiloton-equivalent, or thereabouts, of energy in that explosion.
    You could look up the factors, typical in small-yield (tactical) warhead nuclear explosion, minus radiation and fallout.
    Also, you could look up history, like explosion in Halifax (also happened along the shoreline near a city -- though admittedly Halifax was way less populated than Beirut today): https://en.wikipedia.org/wiki/Halifax_Explosion
    There are other examples of explosions near shorelines:
    https://en.wikipedia.org/wiki/Explosion ... A_Bedenham
    https://en.wikipedia.org/wiki/Texas_City_disaster
    https://en.wikipedia.org/wiki/Bombay_Explosion_(1944)
    https://en.wikipedia.org/wiki/Port_Chicago_disaster
    There's a town in the US with multiple goes at it:
    https://en.wikipedia.org/wiki/South_Amb ... explosions

    So yeah, falling debris could be involved. But the sheer strength of explosion tearing things apart, and sending shockwave and shrapnel around, should not be discounted.

    Phosphoros, thanks for your answer. It shocked me to see that, because I know Beirut and the airport is a 45 minute drive from where this happened (with the whole city in between).

    I'm really very sad to see this. I was in Beirut last year and loved it - a very beautiful country with so many good things. We rented a car and travelled all around. I flew there in an MEA airline A330 and on the flight I watched some documentaries about the country's history, including their entire fleet being destroyed at some point. In the airport there were photos from the civil war with before and after (restoration) pictures and the worst times seemed to be behind them.

    Nearly 3000 tonnes of Ammonium nitrate stored In warehouse, the strength and frequency shockwaves probably caused most of the damage outside of the actual explosion radius.

    Different chemicals have different strengths and potencies, also depends on the surroundings.

    OKC was ammonium nitrate, as well. So this potentially had roughly 1300 times the energy of the OKC bombing.

    The Halifax explosion was the largest man made explosion until the atomic bomb. My wife is from Halifax. So I've read all about it out of curiosity. Very interesting to read about it on the net if you are bored enough.

    It was and killed over 2,000. If it weren’t for a CP Rail worker that pretty much sacrificed his life, hundreds more would have died on an inbound train. Apparently some +110 year old trees still have explosives and shrapnel bits lodged in them to this day.

    RIP to those that died in BEY and wishing those that were injured a full recovery.

    6000 pounds of ammonium nitrate is really weird

    it is told the goverment had confiscated it about six years ago from a ship in the harbour
    reason for the confiscation was danger of explosion

    6000 pounds is less than 3 tons. Are you sure there aren't a few zeros missing somewhere?

    2.750 t of ammonium nitrate, not 6000 pounds. And additional, the "warehouse 12" storage facility, firework was stored and other explosives. Ammonium nitrate needs a fuze and/or extreme heat to explode; first the firework was on fire and has exploded with a medium size explosion as seen in one video (taken from the roof of the grain excavator), later on the ammonium nitrate. Likely the burning and exploding firework has worked as fuze for the huge ammonium nitrate explosion.

    In US units, a ton is 2,000 lb (there are 3 different weight tons) so 5.5 million pounds. I recall ammonium nitrate has less yield compared to TNT, but it is cheap and more stable. A guess would be 5 million pounds TNT. Hiroshima was 15 kTons, this was about 2.5 kTons or 1/6th.

    What idiot put so much into a warehouse so close to population. Explosives are to be stored away from people not essential for the work. The explosive arc to general population would be at least 5 km.

    You are correct that pure ammonium nitrate has a bit less yield than tnt, kg-per-kg. 2.5 kt TNT equivalent sounds about right.
    Which is uncomfortably close to 2.9 kt of Halifax Explosion, the largest man-made explosion of pre-nuclear age.

    About "where to put it". Does Lebanon have a port, with no major population centers near? Would maritime regulations allow a non-sea-worthy, abandoned freighter, being towed there? Would it be legal to break the shipment of confiscated goods into smaller parcels, to ship it overland to various locations through the country? Would it be legal to ship it, overland, at all?
    Sounds like a bureaucratic nightmare, needing escalation "upstairs". Knowing how the bureaucracies work, I'm not surprised the file sat somewhere, collecting dust, while ammonium nitrate sat in the warehouse, caking and waiting.

    And yeah, handling ammonium nitrate is a thankless, difficult, dangerous task for a long time. Here's what happened almost a century ago:

    Oppau is actually a case study in my profession (chemistry). In a black humor sense of way, the workers weren't stupid -- they knew AN could blow up, they knew they were allowed to dynamite caked ammonium sulfate, it was management that allowed them to dynamite AS, and it was management that allowed AS and AN to mix in the same silo (actually, apparently making the caking worse). So the workers made some sensible precautions (like hiding behind a corner); they just didn't realize the precautions weren't near enough, as far as possible yield goes.

    Permits/fire department -- small fee? I don't think that's how it went, if corruption was involved, as you postulate. Just the opposite, if the environment is that of corruption -- it was a government problem (confiscated cargo), shared responsibility of salaried, low-level civil servants, and there was nobody to ask a bribe from. So nobody wanted to touch that can of worms, until it went kaboom.

    Could be falling debris, too. Initial reports say that we are talking a kiloton-equivalent, or thereabouts, of energy in that explosion.
    You could look up the factors, typical in small-yield (tactical) warhead nuclear explosion, minus radiation and fallout.
    Also, you could look up history, like explosion in Halifax (also happened along the shoreline near a city -- though admittedly Halifax was way less populated than Beirut today): https://en.wikipedia.org/wiki/Halifax_Explosion
    There are other examples of explosions near shorelines:

    https://en.wikipedia.org/wiki/Texas_City_disaster
    https://en.wikipedia.org/wiki/Bombay_Explosion_(1944)
    https://en.wikipedia.org/wiki/Port_Chicago_disaster
    There's a town in the US with multiple goes at it:
    https://en.wikipedia.org/wiki/South_Amb ... explosions

    So yeah, falling debris could be involved. But the sheer strength of explosion tearing things apart, and sending shockwave and shrapnel around, should not be discounted.


    The Halifax explosion was the largest man made explosion until the atomic bomb. My wife is from Halifax. So I've read all about it out of curiosity. Very interesting to read about it on the net if you are bored enough.

    My great grandfather was denied permission to marry his intended. Her father took her to Halifax to audit a business there and meet more suitable marriage candidates. That explosion crippled my great grandmother, so the new candidates were no longer interested. My great grandfather sailed to visit my great grandmother in the hospital, from Ohio. He was granted permission to marry her.

    This is tragic. When Tianjin harbor exploded, I couldn't understand why explosives could be stored next to ammonium nitrate and cyanide. How this fraction of explosives was stored boggles the mind.

    Read on the ammo ship explosions during ww2. e.g., Port Chicago disaster:

    https://en.m.wikipedia.org/wiki/Port_Chicago_disaster

    This level of explosion requires help. A small nation doesn't have the resources.
    Winter is coming.

    Well Nitroprill IS Ammonium Nitrate.

    Their skin tones are not inconsistent with Lebanon.

    BTW the current terminal will be replaced by new terminal which has triple capacity

    Nitroprill HD is indeed normal labelling for agricultural grade of AN, manufactured by Rustavi Azot in Georgia.
    This part checks out, as we know the abandoned cargo was shipped from Georgia.
    (disclaimer -- nothing here implies manufacturer liability).

    Storage conditions are appalling. Bottom big bags seem to have collapsed pallets, so forklifting from the bottom is out of question to get them out; only lifting by "ears on top". Front layer of bags is too close to the door, and the door can get hot in direct sunlight. (AN has a crystal formation transit point at 36oC. And it's generally unhealthy to heat nitrates).

    sounds to me like an AN 124 or 225 visit may be in the works for much needed relief...

    No. it fits. I have seen a video of the burning building, taken from top of the grain excavator next to it. This was, when the first explosion (the small one) of the firework has rocked the building, then the camera man was running...before there was the huge second one. The windows in the back fits (from inside) as also the wall/roof shape to the video taken from the roof of the grain excavator from outside, it is "warehouse 12" or one building/warehouse of same shape at the harbor. I say it is the same building, so it is not a fake picture.

    Does someone want to see something shocking? (shocking, not graphic). Before/after gif.

    That the two ships to the right are still there, is a miracle, will like to know, if they are technical sunk and lying on the harbor ground or still afloat. Nice hole were once was the "warehouse 12".....

    Agree I feel the same been numerous times and shocked seeing the videos. Sadly the news reporting more deaths and injuries. It was heard in Cyprus 234KM away .


    Wow...was it?

    Were you in Cyprus when the ammo exploded in 2011? Any comparisons?

    Also wouldnt planes flying around be affected by the shockwave or is it a non event for sth flying at 35000ft?

    Interesting photo but to answer your question about the sunken ship, the before and after pics can be days, weeks, months, years apart..

    The netherlands already has search teams on their way. A chartered 737 (PH-CDE) left around 3 hours ago from Eindhoven. On board are specialized medics, police, firefighters and military search teams. Their dogs and heavy equipment will fly out later today on a C-17.

    This level of explosion requires help. A small nation doesn't have the resources.


    The Halifax and Port Chicago explosions were the basis for the DOD Blast Resistant Design standards still used today. They both had known quantities of ordinance and occurred near the water where the smooth surfaces attenuated the shock wave the least. Looking at the damage to the pier and on shore at various radii allowed for more accurate calculation of the forces involved to cause that damage. The manual establishes various explosive 'arcs' restricting personnel and also to design the bunkers to resist the blast of the adjacent magazine sufficient to not have a sympathetic detonation.

    I don't have the project info with me, so this is by memory. The project required anchoring a blast resistant module (basically a single wide construction trailer) to resist the blast of about 100 tons of missile propellant about 1,000 feet away. The force on the face of the module was over 1,700 PSF for about 1/10 of a second. It took 30 Chance screw augers drilled into the ground some 20 feet down to resist the force the 12'x12' face, around 125 tons of force on the module.
