The volcano eruption in Tambora, Indonesia, in 1815, killed around 92,000 people. The eruption sent fiery ash into the stratosphere, which cooled the world climate for more than a year. In some parts of the world, that year is called 'the year without a summer' because it was so cool. Tambora also destroyed crops, and led to disease and water contamination.
Famous Volcanic Eruptions . About 550 volcanoes have erupted on Earth's surface since recorded history; about 60 are active each year. Far more have erupted unobserved on the ocean floor. Most volcanoes exist at the boundaries of Earth's crustal plates, such as the famous Ring of Fire that surrounds the Pacific Ocean plate. Indonesia holds the record for the greatest number of eruptions, followed by Japan and the USA.
