The IMO (Icelandic Met Office) published the interferogram showing new dike intrusion on Reykjanes Peninsula and deformation associated with the M 5.47 earthquake on 31 July 2022.
Through this interferogram, it’s possible to observe approximately 16 cm of northwestward displacement related to the intrusion, which commenced on the 30th July 2022.
Furthermore, from preliminary deformation modelling results, the top depth of the new dike intrusion beneath Fagradalsfjall appears very shallow – about 1 km and the magma inflow rate is too rapid, almost double that observed during the first dike intrusion in february-march 2021.
In this moment, all the signals (deformation and seismicity) indicate a declining and this was precursory to the eruption which started on 19th March 2021. So the likelihood of an eruption at Fagradalsfjall within the coming days is considered to be substantial.

Thank you to those of you who contributed descriptions of your work for the annual highlights reports. We are always interested in new work to highlight, if you publish something yourself, or see something in-print that would be worthy of…
IAVCE is piloting an eVolcano video project to curate and distribute Volcanology videos. Please consider contributing some content! The eVolcano pilot project includes peer-reviewed videos that are 20-30min long scientific lectures covering different fields and subjects in Volcanology, targeting the…
We are pleased to announce the launch of a volcano model verification and validation initiative “Drivers of Volcano Deformation” (DVD), sponsored by CONVERSE/IAVCEI/Modeling Collaboratory for Subduction. DVD Phase 1 consists of several exercises to test commonly used models for ground deformation at volcanoes. As forward and inverse models of volcano deformation increase in complexity, it…
In the 2018, two earth scientists from Slovakia, Pavol Zahorec and Peter Vajda have teamed up with colleagues from Osservatorio Etneo, Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Catania (Sicily), Daniele Carbone, Filippo Greco and Massimo Cantarero to conduct…
