Eruption of Krakatoa

Date: August 26, 1883 • Location: Labuan, Indonesia

A massive eruption (pictured) destroyed the island of Krakatoa, Indonesia, ejecting so much volcanic ash that average global temperatures fell by as much as 1.2 °C (2.2 °F) over the next year.

Between 19 May and 21 October 1883, the volcanic island of Krakatoa began erupting, lasting more than five months. On 27 August, the island had its most significant eruption, which destroyed over 70% of the island and its surrounding archipelago, the island collapsing into a caldera. The eruption of 27 August had an estimated volcanic explosivity index of 6, and is one of the deadliest and most destructive volcanic events in recorded history; the third explosion of that day, that occurred at 10:02 a.m., remains the loudest-known sound in history.
