The eruption at Santorini (Greece) is considered to be one of the largest in history, and certainly the most massive volcanic explosion in the last 10,000 years.

Pyroclastic flows, one of the most destructive of all volcanic processes, shattered the island of Santorini in 1646 BC.

Pyroclastic flows are terrifying avalanches of gas, rock and lava that can attain temperatures above 1,000 degrees and move at over 100 miles per hour, following the topography of the land. The flows essentially knock down, carry away, shatter or burn down any object they encounter, leaving nothing but destruction in their wake.

The boom was heard as far away as Sweden. Tsunamis rocked the ocean afterwards and the surrounding areas were dark for months.

With some 7 cubic miles of magma expelled, the volcano collapsed, leaving behind a massive crater, an unimaginably huge plume of ash and the resultant pyroclastic flows. A rush of hot, sticky mud and cataclysmic "rock bombs" were ejected out of the crater. Within about a week's time, some 70 meters of volcanic deposits had buried Akrotiri, perfectly preserving the town's frescoes, pots, pans and structures exactly as they were left behind.
