The big underwater volcanic eruption in Tonga earlier this yr spat out the tallest plume of its sort ever recorded, a brand new research reveals. The looming tower of ash, mud and water vapor reached 35.4 miles (57 kilometers) above sea stage, and was the primary plume to make it into the mesosphere — the third layer of Earth’s ambiance.

On Jan. 15, the Hunga Tonga-Hunga Ha’apai volcano, a submarine cone 40 miles (64 km) north of Tonga’s most important island Tongatapu, instantly erupted. The blast was essentially the most highly effective explosion on Earth for greater than 30 years, with an equal drive of 100 Hiroshima bombs. The energetic occasion sparked a tsunami that reached so far as Japan and generated atmospheric shockwaves that induced the ambiance to ring like a bell.
