Krakatoa’s Sound Traveled 3,000 miles

You can envision what a real volcano must be like, even if you've never seen one. The magnitude of the explosion, the cloud of smoke, and the magma rivers. What about the sound, though? Although it might be assumed that it will be loud, the actuality will be unlike anything else on Earth. At least, it is how it appeared when Krakatoa erupted in 1883.

During this eruption, thousands of people perished, and the lava flow was so great that it spread further destruction by crossing the ocean and hitting surrounding islands. People heard the blow 3,000 miles away on the other side of the Indian Ocean, four hours after the eruption.

It took that long for the sound to reach Rodriguez Island, but many there claimed to have heard it. The sound was also noticed by Perth, Australia, locals.
