Krakatoa, 143 years after the loudest sound
On 27 August 1883, at 10:02 in the morning, the island of Krakatoa tore itself apart. It is still the loudest sound anyone has measured. The explosion was heard 3,110 km away in Perth, and on Rodrigues, near Mauritius 4,800 km out in the Indian Ocean, people took it for a ship firing its cannon.
The pressure wave rounded the globe three and a half times. Barographs recorded it passing again and again. The sound went everywhere. Then it stopped.
What stayed was the sky. Ash and sulfur rode into the stratosphere, and for months the sunsets came up red where the volcano had never been seen. In New York, Poughkeepsie and New Haven, fire engines were called out to quench what looked like a conflagration overhead. In Britain, an artist named William Ascroft made thousands of color sketches of the sunsets, trying to keep them.
Ten years later, in 1893, Edvard Munch painted a sky he called “actual blood,” and said the color shrieked. In 2004 an astronomer proposed the red in The Scream is an accurate record of what Norway looked like after Krakatoa. Other scholars disagree. It may have been memory, or clouds, or dread.
The loudest sound in recorded history is remembered as a color.
