The Krakatoa Explosion

Krakatoa, Indonesia
August 26-27, 1883

When this volcanic island exploded and collapsed into the sea, the world felt the effects for years.

What happened?
Ash and steam had been hissing from Krakatoa since May when a series of cataclysmic explosions began on August 26.

The final climactic blow the following day blew the island to bits. The blast was heard almost 3,000 miles away.

When the tower of ash from the explosion collapsed, it sent 130-foot tsunamis surging onto neighboring coastlines. More than 36,000 people lost their lives in Java, Sumatra, and surrounding islands.

Krakatoa had been rumbling for months. Finally it blew, sending a column of gas and ash 50 miles into the sky. When the ash column collapsed, it scorched everything in its path, blackening the sky for two-and-a-half days.

When a volcano releases that much ash and gas, the effects are global—and long-term. A massive eruption like Krakatoa’s can alter Earth’s climate for years.
