When a volcano in the South Pacific Kingdom of Tonga began erupting in late-December 2021 and then violently exploded in mid-January 2022, NASA scientist Jim Garvin and colleagues were unusually well positioned to study the events. Ever since new land rose above the water surface in 2015 and joined two existing islands, Garvin and an international team of researchers have been monitoring changes there. The team used a combination of satellite observations and surface-based geophysical surveys to track the evolution of the rapidly changing piece of Earth. Now all of the new land is gone, along with large chunks of the two older islands. Story, pictures and links - NASA Earth Observatory.

NASA's TRMM satellite passed over Tropical Cyclone Ian three days in a row and captured rainfall and thunderstorm cloud height data about the deadly storm as it strengthened and weakened. Powerful thunderstorms in Ian's eye wall were found reaching heights of about 15 km/9.3 miles. TRMM's data was used to create a 3-D flyby animation of Ian's well defined eye on January 11, 2014 at 0833 UTC [9:30pm Tonga local time].
