On August 26-27, 1883, one of the most notorious volcanic eruptions in history occurred. Krakatau (often spelled Krakatoa) erupted with an estimated 10,000 thousand times the force of the Hiroshima atomic bomb. The eruption was so violent that two-thirds of the island of Krakatoa and its surrounding archipelago were destroyed: about 23 square kilometers of Earth sank into the Sunda Strait.
Across Java and Sumatra, burning rock rained down, damaging and even destroying settlements. The sky went black.
