The leading edge of a lava flow destroys a road on 8 February 2024 near the town of Grindavík, Iceland. Fracturing and tectonic stress can drive ultrarapid flow into dikes, as in the event that preceded Iceland’s recent eruptive episodes. Learn more: scim.ag/6dF

Another #Reykjanes #eruption, another seismic station in the firing line! This time @CamVolcSeis's SYLA, around 500 m from the fissure. Data is streaming, and beautifully shows the ~ 40 minutes of seismicity as the dike intruded, and the tremor once the eruption began at 6.02am

We are recruiting a PhD student in Geophysics at the University of Iceland! Engage in innovative research on volcano-tectonic seismicity right where the action is happening. Also, you'll have the potential to do exciting fieldwork. Apply by March 15, 2024. euraxess.ec.europa.eu/jobs/193522

Good number of Raspberry-Shake @raspishake seismometers in Reykjavík, Iceland. Traces from Oct. 4 M4.9 earthquake in Bárðarbunga. @EqEngSeis is this useful for array processing?

Fantastic trip around northern Scotland and Skye with the Geological Society of Iceland. Dino 🦖 tracks, beers, Moine thrust (good name for a beer) and lots of great geology with Durness Deep Time museum master, Bjorn Hardarson
