Full Answer

The eruption of Krakatoa took place in 1883 and was so powerful that it split the island in half. It was so loud that it was heard 1,300 miles away in the Andaman Islands, 2,000 miles away in Australia and up to 3,000 miles away in the island of Mauritius. In terms of decibels this sound was over 194, which is when sound stops moving through air and actually starts pushing it.
