Over 135 years ago, it is believed that the loudest sound ever heard on earth was experienced. This sound was produced by the eruption of the Krakotoa volcano, found on the Lampung province of Indonesia. The eruption was so loud that the eardrums of people 40 miles away were ruptured. In addition, it was reported to have been heard by residents of Rodrigues Island, near Mauritius, more than 3,000 miles away!
For perspective, O’Neill Engineered Systems Inc. is located in Hartland, Wisconsin. Milwaukee, the state’s largest city, is roughly 27 miles away. If the 1883 Krakatoa eruption had somehow happened in Hartland, people throughout the Milwaukee metro region would have been at risk of ruptured eardrums. Even more remarkably, people as far west as Alaska and as far east as Ireland might’ve heard the sound.
Although the wave of pressure past 3,000 miles grew too quiet for humans, instruments reported reverberations for days. Sound pressure this violent was capable of destroying the entire island of Krakotoa and everything in its path.
