The Hunga Tonga-Hunga Haʻapai eruption in January 2022 is widely considered the largest volcanic event captured from space in modern times, setting records for water vapor in the stratosphere, generating immense shockwaves circling the globe, and producing extreme lightning, all observed by satellites like GOES-17 and the ISS, with plumes reaching into the mesosphere. It was the biggest underwater explosion ever recorded, disrupting satellites and causing tsunamis worldwide. | Galaxies Video
