A quick 🧵 about the *size* of the #HungaTonga eruption:

Volcanic eruptions are generally assigned a VEI—Volcanic Explosivity Index—value.

This scale is a general indicator of the explosive character of an eruptive event.

This scale, described by Christopher Newhall and Stephen Self in a 1982 paper, is a general indicator of the explosive character of an eruptive event, and reflects the interplay of an eruption's magnitude, intensity, and energy release rate.

The VEI rating scale employs a set of criteria including ejecta volume, style of eruption, plume height, and injection of gases into the troposphere and stratosphere.

There's no question that the #Tongaeruption was huge—it absolutely was.

2022 könnte einen Hauch kühler werden als erwartet. Hunga Tonga Hunga Ha'apai bläst Asche in die Stratosphäre. Hoffentlich haben alle im Umkreis die #Tsunami-Warnung beachtet. Man beachte die Reaktionen auf den Tweet.
Erstaunlich dünnes Medienecho hierzulande. Hier ein sehr interessanter Text von einem neuseeländischen Vulkanologen, der diesen Vulkan erforscht, bei @TheConversation. Beunruhigender Schluss. #Tongaeruption…
Der eigentliche Krater ist unter Wasser und ungefähr so groß wie die ganze entzweigesprengte Insel, deren Bilder gerade die Runde machen (Bild aus dem oben verlinkten Text).
