The word 'volcano' derives from the Roman God of fire- Vulcan. The deadliest volcanic eruption was the one of Tambora volcano in Indonesia. It happened in 1815 and killed roughly 90,000 people. Most of these people didn't die in the flaming lava, but from starvation and diseases caused by the eruption. Another volcano (Krakatoa) erupted in Indonesia in 1883 and the dust that it put in the Earth's atmosphere made sunsets appear green and the Moon look blue for almost 2 years. It is difficult to imagine, but consider the amount of dust that a volcano puts in the air. For example, Mount St. Helens dumped approximately 540 million tons of ash for 9 hours of vigorous activity when it erupted on 18 May 1980.
