The Day Krakatoa Blew Itself Apart
On August 26, 1883, the Indonesian island of Krakatoa began a cataclysmic eruption that would be heard 3,000 miles away and dim skies around the world.
The island had been grumbling for months. Krakatoa — a small volcanic island in the Sunda Strait between Java and Sumatra, in what is now Indonesia — had rumbled back to life in May 1883 after two centuries of quiet. Ships passing through the strait reported columns of ash and pumice floating on the sea. But nobody on the afternoon of August 26, 1883, could have imagined what was coming.
That afternoon, the volcano entered its paroxysmal phase — the violent climax of the eruption. Explosion after explosion tore the island apart, each one hurling ash miles into the sky. The eruptions continued through the night and into the next day, building toward a final, apocalyptic blast on the morning of August 27 that destroyed most of the island itself.
It was, by most accounts, the loudest sound in recorded human history. The final explosion was heard 3,000 miles away — across the Indian Ocean in Mauritius, and as far as Australia. Sailors 40 miles from the island had their eardrums ruptured. Barometers around the world registered the pressure wave as it circled the planet several times over.
The sea turned murderous. The collapse of the island displaced enormous volumes of water, sending tsunamis racing across the Sunda Strait. Towering waves slammed into the coasts of Java and Sumatra, sweeping away whole towns and villages. More than 36,000 people were killed — the overwhelming majority by the tsunamis, not the eruption itself.
Then came the strange, beautiful aftermath. So much ash and gas had been blasted into the upper atmosphere that sunlight itself was altered. For months, people around the world saw blood-red sunsets of unearthly brilliance. The sun appeared blue or green in some places; in others, it seemed dimmed at noon. Global temperatures dipped. Painters captured the eerie skies — some art historians believe the lurid red sky in Edvard Munch's famous 1893 painting "The Scream" was inspired by the volcanic sunsets he saw in Norway in the years after the eruption.
Krakatoa itself was gone — much of the island had vanished into the sea, leaving a submerged caldera. But the story wasn't over. In 1927, a new island began rising from the same spot: Anak Krakatau — "Child of Krakatoa" — which has been growing and erupting ever since.
The 1883 eruption remains the benchmark against which all volcanic catastrophes are measured: a reminder that the ground beneath our feet is thin, and that a single island's fury can dim the sun for the entire planet.
