Developments in satellite tv for pc know-how over the previous decade have allowed the world to witness the devastating Hunga Tonga-Hunga Ha’apai eruption and its aftermath in actual time and in unprecedented element. The findings would possibly make clear the anatomy of uncommon explosive volcanic eruptions and their results on the planet. But satellites are additionally serving to volcanologists control Earth’s extra widespread (although much less eye-catching) outbursts. 

The final time a volcano erupted as violently as Hunga Tonga-Hunga Ha’apai was 30 years in the past. At that point, satellites monitoring Earth have been few and much between. Those watching the planet’s floor have been largely run by the navy. The European Space Agency (ESA), now an Earth-observing super-power, was solely about to launch its first Earth-observing mission, the Remote-Sensing Satellite-1 (ERS-1). Cubesats that have since turn into a cornerstone of business Earth-observing constellations, such these of the U.S.-based firm Planet, have been but to be invented.
