The 1883 Krakatau eruption: a year of blue Moons
August 1883 saw the world tremble with the eruption of Krakatau, a volcano in the Sunda Strait connecting the Java Sea and the Indian Ocean.

The Krakatau eruption had an explosive force of a 200-megatonne bomb, killing more than 36,000 people and cooling the entire Earth by an average of 0.6°C for months to come.

The awakening of Krakatau in 1883 was one of the deadliest volcanic eruptions in modern history, second only to the eruption of Tambora in 1815, which killed 60,000 people.
