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.

The first one is that we are entering an #ElNiño period.
#Historically, 👉El Niño events have been the primary trigger for global #temperatures records👈 being broken. "
The second natural booster one is massive #eruptions of #underwater #volcanos:

If you weren’t able to attend #AGU22, here is the poster I presented about #lightning during the eruption of #Hunga #Volcano.
Anybody here going to #AGU23? I will be attending for the first time and presenting work on #lightning in the #Hunga #Volcano.
Die Druckwelle des Vulkans #Hunga #Tonga-Hunga Ha'apai hat jetzt auch #Berlin erreicht, gut zu erkennen auf dem Luftdruck kurz nach 20 Uhr. /JS
