856 – Damghan earthquake: An earthquake near the Persian city of Damghan kills an estimated 200,000 people, the sixth deadliest earthquake in recorded history.

Considering how people lived and how few there were compared to today, that must have been one heck of an earthquake.

2008 – An ash dike ruptured at a solid waste containment area in Roane County, Tennessee, releasing 1.1 billion US gallons (4,200,000 m³) of coal fly ash slurry.

Now that's what you call real pollution!
