Krakatoa, 1883: The Eruption Heard 3,000 Miles Away

A volcanic eruption in 1883 was heard 3,000 miles away—and that was only the first strange thing Krakatoa did. In this episode, we follow the Krakatoa eruption, the tsunamis, the atmospheric pressure wave, and the global climate effects that turned one island disaster into worldwide chaos, so listen now before you think you already know the story.In 1883, Krakatoa didn’t just erupt — it sent a shockwave through the atmosphere, the oceans, and the world’s news network. This episode follows the Krakatoa eruption heard 3,000 miles away, the tsunamis that followed, and the strange global climate effects that made sunsets look like art and disaster at the same time.• The Krakatoa eruption reached VEI 6 and ranks among the most powerful volcanic events in recorded history. • Sound from the final blast was reported thousands of miles away, and the pressure wave circled the globe. • Tsunamis caused most of the death toll, with coastal villages in Java and Sumatra devastated. • Ash and sulfur in the stratosphere changed skies worldwide and cooled the planet for years.
