Gen. Sandworm, the asnwer to your question I believe is the Halifax Explosion!
The Halifax Explosion occurred on December 6, 1917, in Halifax, Nova Scotia, Canada when a munitions ship, the Mont Blanc, collided with a Norwegian ship, the Imo, headed for wartime Belgium. The Mont Blanc caught fire, and then exploded, killing 1,635 people and injuring thousands more. The Explosion caused a tsunami, an earthquake, and a pressure wave of air so powerful that it snapped trees, bent iron rails, and demolished buildings, carrying the fragments of them for hundreds of metres.
