Askja Volcano Update; Magma is on the Move in Central Iceland

Описание: In Iceland, while a volcanic eruption is ongoing southwest of the capital city Reykjavik, it appears that a fresh magmatic intrusion is ongoing at a separate volcano in the center of the country. There, the Askja volcano is producing an unusually high rate of ground deformation, temporarily placing it as the site of the highest uplift at a volcano on the planet. This video discusses Askja's current activity along with a separate magmatic intrusion which lasted from 2021 to 2023.

Disclaimer: The apparent uplift signal at Askja could still end up being a false positive, in which case the description of this video will be updated.
