The pressure wave from the final explosion was recorded on barographs around the world, which continued to register it up to 5 days after the explosion. The recordings show that the shockwave from the final explosion reverberated around the globe 7 times in total.[9] Ash was propelled to a height of 80 km. The eruptions diminished rapidly after that point, and by the morning of August 28 Krakatoa was quiet.180Db@100 miles???Try 1 meter?</blockquote>
