Two geostationary satellites captured some incredible images of an explosive eruption from an underwater volcano in the south Pacific on January 15, 2022. The event started at approximately 04:00 UT. The event was captured by NOAA’s GOES-17 West satellite and the Japanese Meteorological Agency’s Himawari-8 satellite.

The explosive eruption occurred 70 km north of the island of Nuku’ alofa, Tonga. Nuku’ alofa is 780 km southeast of Fiji and 810 km southwest of American Samoa. The USGS’ preliminary magnitude estimate is 5.8 for the seismic event associated with the eruption. The diameter of the ejecta cloud in this image is approximately 600 km. The annotations are mine.
