On Dec. 6, 1917, the French cargo ship Mont-Blanc, fully loaded with explosives, collided with the Norwegian vessel Imo in The Narrows, a strait between Halifax and Dartmouth.
A fire on board Mont-Blanc ignited the explosives in the ship’s hold, causing the largest man-made explosion the world had ever seen.
The explosion levelled much of the city and sent shards of glass and burning debris flying for kilometres.
The blast was felt as far away as Sydney, N.S., 435 kilometres away.
When the smoke cleared, 2,000 people were dead and another 9,000 were wounded. Half of the city’s population, 25,000 people, were left homeless.
Halifax 1917 taught us more about explosions than we’d known before – the boat burst into flame and the munitions on board exploded. Sending out a shockblast sphere – the force of air leveled the town, and the shock wave to the bottom of the harbour and bouncing back, buidling force.
Until nuclear explosions, it was the biggest human caused explosion.
the biggest human cause explosion is credited to Russia’s Tsar bomb, the shockwave from that explosion traveled 3 detectable times around the earth.
