Huge Tonga underwater volcano eruption captured in stunning satellite video

A powerful underwater volcano eruption in Tonga on Saturday (Jan. 15) was captured as it happened in stunning images from an Earth-watching satellite, showing the sheer power for the explosive event in the South Pacific. 

The volcano eruption on the island of Hunga Tonga-Hunga Ha’apai is visible as a spectacular explosion in views from the GOES West Earth-observing satellite operated by the U.S. National Oceanic and Atmospheric Administration (NOAA). A video of the eruption shows a vast plume from the volcano rising high into the atmosphere like a giant mushroom during the eruption as a shockwave extends outward from Hunga Tonga-Hunga Ha’apai, one of the 170 islands that make up the South Pacific kingdom of Tonga.

The eruption spawned a 4-foot tsunami that hit Tonga’s capital of Nuku’alofa, which is about 40 miles (65 kilometers) south of the volcano. A sonic boom from the eruption was heard across the Pacific Ocean, reaching as far away as Alaska, according to the Associated Press.
