REPULSIVE

The 1883 eruption of Krakatoa is one of the most catastrophic volcanic events in recorded history. Located in the Sunda Strait between Java and Sumatra, Indonesia, the eruption began on May 20, 1883, and culminated in a series of explosive eruptions on August 26 and 27.

The eruption peaked on August 27, when a series of violent explosions destroyed over 70% of the island of Krakatoa. The most significant explosion occurred at approximately 10:00 AM, producing sound waves that were heard as far away as 4,800 kilometers (about 3,000 miles) in places like Australia and Mauritius.

The eruption expelled an estimated 25 cubic kilometers (6 cubic miles) of rock, ash, and pumice into the atmosphere, creating ash clouds that reached heights of up to 27 kilometers (about 17 miles) into the stratosphere. It also caused two-thirds of the island to collapse and triggered massive tsunamis reaching heights of up to 46 meters (151 feet).

The volcanic eruption generated a sound level of around 310 dB. To put this into perspective, sounds above 85 dB can cause hearing damage with prolonged exposure, while sounds at 194 dB transition into shock waves capable of causing physical destruction.

In comparison, other loud sounds include the Saturn V rocket launch, which reaches about 204 dB, and natural events like meteor explosions. However, none come close to the catastrophic volume of Krakatoa.
