The Petrology and Geochemistry of the 2021 Fagradalsfjall Eruption, Iceland: An Eruption Sourced From Multiple, Compositionally Diverse, Near‐Moho Sills We use high frequency sampling to observe rapid changes in lava composition during the 183 day 2021 Fagradalsfjall eruption The eruption was sourced from 12 to 15 km depth, corresponding to the l...

My big paper on the 2021 Fagradalsfjall eruption is finally out! If you want to understand the recent eruptions on the Reykjanes Peninsula better, look no further: doi.org/10.1029/2024...
Let’s dive in to what we found: 🧵

Step 1 of the journey to #AGU2023 is underway!

Swing by my poster on **Monday morning** (V11D-0090) to hear the latest story on seismicity measured during the recent uplift of #Askja #volcano, including some exciting preliminary results from an epic summer of fieldwork 🌋🇮🇸😁⚒️

We've added two new, updated maps to our post, tracking the latest seismic data in Iceland. Here's one; head to our blog to find the other one: earthquakeinsights.substack.com/p/volcanic-e...

vafri.is/quake is a good accompaniment to skjalftalisa - shows all the automatic solutions as they are published by the met office. (With the trade-off that it obvs has less reliable locations and contains some artefacts, particularly during super intense periods)

This morning at 05:35 an earthquake of M3.9, 1km NW of Mt. Thorbjorn on the Reykjanes peninsula, a seismic swarm started there just after midnight. The earthquake activity there is ongoing. It was felt in the town of Grindavík and in more settlements. en.vedur.is/earthq.../ea...
