Tongan Geologists Observe Earlier Eruption of Hunga Tonga-Hunga Ha'apai Volcano

A team of Tongan geologists observed a massive plume of ash rising skyward during a continuous eruption of the Hunga Tonga-Hunga Ha’apai volcano on January 14.

Images released by the Tonga Geological Services show what they said was a 5km (3.1 miles) wide column of ash, gas, and steam rising 18-20km (11-12.5 miles) above sea level on Friday.

On Saturday, January 15, a further volcanic eruption triggered tsunami alerts for several Pacific nations, Australia, New Zealand and areas on the Pacific coastlines of Japan and the US. Credit: Tonga Geological Services via Storyful
