What is the farthest distance away that a volcano has been heard erupting?

The farthest distance from which a volcanic eruption has been heard is approximately 3,000 miles (about 4,800 kilometers). This record was set during the 1883 eruption of Krakatoa in Indonesia. The explosive sounds of the eruption reached as far away as the island of Rodrigues in the Indian ocean, demonstrating the extraordinary power of the eruption and its ability to transmit sound over vast distances.
