The RaspberryShake team makes a high-quality "Raspberry Boom" infrasound detector for hobbyists. Next Krakatoa, you can be prepared to detect it yourself. :) The "RBOOM" sensor alone is $300+, but you can also buy a kit and integrate it into a Raspberry Shake home seismometer setup. I run a RS seismometerat home, but not the infrasound sensor. "From incoming harsh weather, planes flying overhead, gun fire and nuclear testing, to volcanoes erupting on remote islands in the Pacific Ocean and meteors exploding over the Atlantic… See all these and more. Discover the untold secrets that are out there with your own RBOOM!"
