How many tons of TNT is Tambora?
An explosive eruption like Tambora releases huge amount of energy. A rough estimate for the 1815 event is ~1.4 x 10 20 joules of energy were released across the few days of eruption. One ton of TNT releases ~4.2 x 10 9 joules, so this eruption was 33 billion tons of TNT.

Why did Mt Tambora erupt?
The Tambora eruption was caused by ocean water penetrating cracks and fissures in the mountain. When it reacted with magma deep inside the volcano, massive pressure built up, causing the mountain to blow itself apart. In 1812, the mountain began to emit small amounts of ash and steam.
