To the surprise of many, the Hunga Tonga Hunga Ha'apai volcano is still likely erupting right now. Additionally, a survey of the ocean floor was just published, revealing that the January 15th eruption was far larger than originally thought. In fact, the eruption truly was a VEI 6, as indicated in part by the 4 kilometer wide caldera which is now 750 meters deeper. This video will discuss how the size of the eruption was reached, and why many scientists including myself got the initial size of the eruption so wrong.

This Week in Volcano News; Hunga Tonga is Erupting, Hualalai Earthquake

In the last week, it was discovered that the Hunga Tonga Hunga Ha'apai volcano is still erupting. New information shows that the volcano produced a VEI 6 eruption, deepening its caldera by more than 700 meters or 2000 feet. Meanwhile in Hawaii, a moderate magnitude earthquake occurred on the flanks of the Hualalai volcano, leading some to suspect that it was volcanic in origin. And, in Papua New Guinea, magmatic uplift was detected at a volcano which has not erupted in more than 135 years. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.

Hunga Tonga Volcano Update; The Cause of Unusual Sunsets around

AdiGaia's picture

The eruption of the Hunga Tonga Hunga Ha'apai volcano is still ongoing at the present, although this is confined to a series of underwater vents. While its above water activity has ceased, its eruption has led to the generation of some unusually vivid and colorful sunsets. These unusual sunsets are caused by the abundance aerosols and sulfur dioxide which the eruption ejected high into the atmosphere. As a result, colorful sunsets will continue to occur for as many as 18 months following January of 2022.
