Pressure wave

"The pressure wave generated by the colossal third explosion radiated out from Krakatoa at 1,086 km/h (675 mph). The eruption is estimated to have reached 310 dB, loud enough to be heard clearly 5,000 kilometres (3,100 mi) away.[7]:248 It was so powerful that it ruptured the eardrums of sailors 64 km (40 miles) away on ships in the Sunda Strait,[7]:235 and caused a spike of more than 8.5 kilopascals (2.5 inHg) in pressure gauges 160 km (100 miles) away, attached to gasometers in the Batavia gasworks, sending them off the scale.[note 1]

The pressure wave was recorded on barographs all over the world. Several barographs recorded the wave seven times over the course of five days: four times with the wave traveling away from the volcano to its antipodal point, and three times travelling back to the volcano.[4]:63 Hence, the wave rounded the globe three and a half times. Ash was propelled to an estimated height of 80 km (50 mi)."

1881 Atlantic hurricane season


https://en.wikipedia.org/wiki/1881_Atlantic_hurricane_season#Hurricane_Five


Surprisingly, this hurricane came in #10 for causing the number of deaths.....back when we didn't have watches and warnings or the ability to move people out of its path quickly.

In the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated
