The Halifax explosion occurred on December 6th, 1917, in Halifax, Novia Scotia. It happened after two ships collided. A fire started, and because the French ship Mont Blanc was carrying explosives, the ships blew up, creating a tsunami in the bay. Rubble flew up into the air and onto the city as explosions rocked the provincial capital. About 2,000 people died because of the explosion and a further 9,000 injured. Damages were estimated at more than $430,000 CAD today.
