L'eruzione vulcanica di Tonga è stata innescata da un'esplosione equivalente a “cinque bombe nucleari sotterranee”
#geologia #Hunga Tonga
Quella del vulcano sottomarino Hunga Tonga è stata una delle più grandi eruzioni vulcaniche della storia e ora, a due anni di distanza, una nuova ricerca ha rivelato il suo principale fattore scatenante.

The #volcanic eruptions 🌋 of #Hunga 2022 attracted a lot of attention as they hurled large amounts of water vapor💧into great altitudes of the #atmosphere, considerably increasing stratospheric moisture. However, there is a second, indirect pathway, leading to increased moisture fluxes into the stratosphere after volcanic eruptions. #MPIM_scientist Clarissa Kroll find that for #Pinatubo-magnitude eruptions both pathways can be comparable.

Indirect moisture injections to the stratosphere after a Pinatubo-sized volcanic eruption could be comparable to direct injection observed after the 2022 Hunga Tonga eruptions, according to a quantification based on the warming of the lowest cold-point temperatures in the tropical tropopause layer.
