Reply #18: How about the 1917 Halifax Fire? [View All]

The largest man-made explosion the world has ever seen..

"Buildings within a radius of half a mile of the explosion were totally destroyed and that up to one mile they were very largely rendered uninhabitable and dangerous. No section of Halifax city escaped serious damage…
More or less severe damage was caused as far away as Sackville and Windsor Junction, 9 or 10 miles (away from) the explosion… At Truro, 62 miles, and New Glasgow, 78 miles, the shock was sufficient to jar buildings very appreciably, and even to shake articles from shelves. Even as far away as Charlottetown, 135 miles, and North Cape Breton, 225 miles, the explosion was distinctly felt or heard."
