On August 27, 1883, a volcano was erupted on the island of Krakatoa, which is situated between Java and Sumatra in Indonesia made a sound which was so loud that ever the earth was made.
This sound was so loud that it was heard 1,300 miles away in the Andaman and Nicobar islands, 2,000 miles away in New Guinea and Western Australia and even 3,000 miles away in the Indian Ocean island of Rodrigues, near Mauritius. In all, it was heard by people in over 50 different geographical locations all over the globe.
This volcano was erupted with such a force that it tore the island apart and also created deadly tsunami with waves over 100 feet (30 meters) in height. 165 villages in the coastal regions were totally destroyed with a estimated death of 36,417 people.
There was a British ship called Norham Castle which was 40 miles from Krakatoa at the time of the explosion. The ship’s captain wrote in his log,
“So violent are the explosions that the ear-drums of over half my crew have been shattered. My last thoughts are with my dear wife. I am convinced that the Day of Judgement has come.”The maximum hearing limit of loud sound for human beings is 120 dB. While painful damage to the ear occurs for human beings at about 140 dB. This Krakatoa explosion registered 172 decibels at 100 miles from the source. This is so loud, that it is against the hearing limits of human beings.
This volcanic eruption in Krakatoa also created a high pressure waves in the atmosphere that it circled the globe three to four times in each direction.
