The Halifax Explosion was a disaster that occurred in Halifax, Nova Scotia, Canada, on the morning of 6 December 1917. SS Mont-Blanc, a French cargo ship laden with high explosives, collided with the Norwegian vessel SS Imo in the Narrows, a strait connecting the upper Halifax Harbour to Bedford Basin. A fire on board the French ship ignited her cargo, causing a massive explosion that devastated the Richmond district of Halifax. Approximately 2,000 people were killed by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured.[1] The blast was the largest man-made explosion at the time,[2] releasing the equivalent energy of roughly 2.9 kilotons of TNT (12,000 GJ).[3]
