How Big Was The Beirut Blast?

We all know by now that it was VERY big. However, Shipwreckedcrew offers a comparison that we in America can identity with.

It appears that the explosion in Beirut may have been the result of an abandoned shipment of ammonium nitrate that was left in storage at the Beirut port for seven years--it's a bit of a long story: Abandoned Shipment of Ammonium Nitrate Behind the Explosion in Beirut Today?? Recall that the bomb that Timothy McVeigh constructed to blow up the Murrah Federal Building was made from ammonium nitrate, too. So:

The Ammonium Nitrate being stored in a Beirut warehouse consisted of 2750 tons  — 55,000 pounds or approximately 25,000 kgs.  By comparison, the Ammonium Nitrate bomb built by Timonthy McVeigh that destroyed the Murrah Federal Building in Oklahoma City consisted of only 2200 kgs of Ammonium Nitrate.  That means the Beirut explosion was roughly the equivalent of a bomb 12 times larger than the one that did this:


  1. 2750 tons = 5.5 Million pounds ~ 2.5 Million Kg

  2. 2200 kgs = 4850 lbs (little more than 2 tons)

  3. Anon is correct. A better comparison is the Texas City blast in 1947. It had about 2200 tons aboard a French ship.

  4. Bigger than this...

  5. Trump said yesterday his command thinks it was an attack.

    BTW, Sally Yates will be testifying today in the Senate, 10am.

    1. She's already paving the road bed previously smoothed and levelled by the DS that it all was Comey's idea and the buck should stop there. If he's offered a relaxing stay at the NNMC with the 16th floor all to himself or a moonlit walk in Ft. Marcy Park I recommend he look for door no. 3.

  6. A ton is 2,000lbs. 2,750 tons is 5.5 MILLION lbs.

    Although obviously a massive explosion with a significant visible blast wave, it's difficult to determine actual scale from the various imagery.

  7. The 1944 Port Chicago disaster during WWII seems comparable in size: 4600 tons of explosives with more than 5000 barrels of heavy fuel oil loaded on SS A.E. Bryan. Then there were the sympathetic detonations of ordnance staged on the pier still to be loaded.


  8. Holy crap.
