What if Krakatoa erupted today?

Say Krakatoa's eruption of 1883 happens again at ten o'clock this morning, between Java and Sumatra. It made what's usually called the loudest sound in recorded history. Within minutes its pressure wave reaches Jakarta. Close to the volcano the eruption kills, and the sea kills far more. In about four hours the wave reaches Rodrigues, almost 4,800 kilometres away, where it would still sound like distant guns. The ring goes round the Earth for days, passing over your house up to seven times. In September 2026, Anak Krakatau erupted and shut eight airports. That was the small version. 0:00 The blast and its reach 0:45 The vent 1:01 The first hundred kilometres 1:52 Jakarta, 150 km 2:49 The water 3:52 Ash and the airports 4:47 The edge of hearing 5:52 The ring goes round, and the instruments 7:06 The sea, nudged far away 7:40 The sky 8:29 The year after 8:58 The real odds #WhatIf #Krakatoa #ScienceExplained #Volcano #Physics
