rhamphotheca: The Greatest Volcanic Eruption in Human History by Our Amazing Planet On April 10, 1815, the Indonesian volcano of Mount Tambora exploded in the largest eruption in recorded history. On the Volcanic Explosivity Index (VEI), a classification system akin to the scale used to rate earthquakes, the Tambora eruption rate a VEI-7. The scale runs from 1 to 8, with each number being approximately 10 times more powerful than the previous one. There haven’t been any VEI-8s in the last 10,000 years. The Tambora eruption killed at least 88,000 people. The massive eruption — heard  on Sumatra Island, more than 1,200 miles (1,930 km) away — spewed an estimated 36 cubic miles (150 cubic kilometers) of tephra — exploded rock and ash — into the air.
