Volcanoes
Sumbawa lies within the Pacific Ring of Fire. It is a volcanic island, including Mount Tambora (8°14’41”S, 117°59’35”E) which exploded in April 1815, the most destructive volcanic eruption in modern history (roughly four times larger than the 1883 eruption of Krakatoa, between Java and Sumatra, in terms of volume of magma ejected). The eruption killed as many as 72,000. It also apparently destroyed a small culture of Southeast Asian affinity, known to archaeologists as the Tamboran kingdom. It launched 100 cubic kilometres (24 cu mi) of ash into the upper atmosphere, which caused 1816 to be the "year without a summer".
