This 100-year-old explosion completely dwarfs the 'mother of all bombs' blast

On April 13, the US military dropped the most powerful non-nuclear bomb in its arsenal on an ISIS stronghold in Afghanistan.Nicknamed the "Mother of All Bombs" (but officially called the GBU-43/B Massive Ordnance Air Blast Bomb), the 30-foot-long munition allegedly crushed a network of caves, tunnels, and bunkers dug into a remote mountainside.The strike was akin to setting off about 11 tons of TNT ' a school bus' weight worth of explosives.However, the attack pales in comparison to an accidental explosion that rocked a coastal town nearly three decades before the first atomic bomb.On the morning of December 6, 1917, a ship detonated in the harbor of Halifax, Nova Scotia, unleashing a blast equivalent to about 3,000 tons of TNT.The resulting shockwave instantly killed more than 1,000 people, threw a cargo ship like a bath toy, and created a 50-foot-tall tidal wave.This is the incredible and horrifying story of the Halifax Explosion: the largest human-made, non-nuclear blast in history.SEE ALSO:The US government just declassified 750 movies of nuclear explosionsDON'T MISS:If a nuclear bomb is dropped on your city, here's where you should run and hideBy December 1917, World War I had been raging for three years.

The ship was en route from the Netherlands to ferry supplies back to a war-ravaged Belgium.Source: NASA Safety Center At the same time, the SS Mont Blanc was bound to return to France carrying a host of highly explosive materials: 2,367 tons of picric acid, 62 tons of guncotton, 250 tons of TNT, and 246 tons of benzol in barrels below decks.
