[QUOTE="ST33M, post: 3559646, member: 580763"] 181.3 has been recorded recently. 200db+ can be achieved only under water, except for the explosion of mount kraka. But back then they didn't have as tough and accurate of mics as we do now. On August 27, the volcano entered the final cataclysmic stage of its eruption. Four enormous explosions took place at 5:30 a.m., 6:42 a.m., 8:20 a.m., and 10:02 a.m., the last of which was worst and loudest. Each was accompanied by very large tsunamis believed to have been over 30 meters (100 ft) high in places. A large area of the Sunda Strait and a number of places on the Sumatran coast were affected by pyroclastic flows from the volcano. The explosions were so violent that they were heard 2,200 miles (3,500 km) away in Australia and the island of Rodrigues near Mauritius, 4,800 km away; the sound of Krakatoa's destruction is believed to be the loudest sound in recorded history, reaching levels of 180 dBSPL 100 miles (160 km) away.[4] Ash was propelled to a height of 50 miles (80 km). The eruptions diminished rapidly after that point, and by the morning of August 28 Krakatoa was quiet. Info found here.
