Excited to announce my return to the @uni_iceland as a tenure track Research Specialist in Seismology starting Jan 1 2024! My journey has taken me from Iceland to @Stanford, @Caltech, and @ETH, now it brings me back home. Looking forward to exploring new frontiers in #seismology

[Elías Rafn Heimisson @EliasHeimisson]

Great and pioneering work, I'm honored to have been a part of it 🙏

🚨🚨🚨New paper in EPSL 🚨🚨🚨

[Luca Dal Zilio @lucadalzilio]

🚨 Just published in Earth and Planetary Science Letters! In collaboration with Luyuan and @EliasHeimisson, we explored how poroelasticity affects rupture propagation across fault stepovers and its impact on earthquake hazards.

Back in grad school, I always thought we should tackle the dike trajectories problem in a biaxial stress field more rigorously. Although I never took it very far, I'm thrilled to see @LBlackstone_ has done an outstanding job with it!

[Elías Rafn Heimisson @EliasHeimisson]

We challenge the common assumption that fluid flow from a fault into the surrounding bulk can be disregarded due to permeability contrasts. Our findings reveal that, despite fairly high permeability contrasts, fluids do not travel far without leaking into the bulk.

🚨🚨🚨 Brand new open access paper with @Jyuhon1024
Here we explore using boundary integrals as a substitute for homogeneous bulk in simulating fluid flow within faults in essentially infinite domains.

Sometimes... I do more mechanics than geo 🤷‍♂️

I am looking for a PhD student passionate about InSAR and looking for advanced research opportunities. Please help in spreading the word to interested students. Thank you! More info: https://t.co/rAdZLNviXm

[Dr Tom Winder @twinderseis]

Please consider coming to @Haskoli_Islands to work with @EliasHeimisson and me on the spectacular sequence of seismicity at Bárðarbunga #volcano over the past 10 years - including even more spectacular fieldwork on the Vatnajökull ice cap (+Askja, the Reykjanes Peninsula & more)!

[Elías Rafn Heimisson @EliasHeimisson]

@seismogenic Yes! Just e-mail me and we'll set up a meeting.

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. https://t.co/0VE6T2tnHN

@hafsteinn

[Elías Rafn Heimisson @EliasHeimisson]

But there is more! We are recruiting for a 2nd PhD opportunity in Geophysics @uni_iceland, focusing on fault movements and earthquake predictability using numerical simulations and machine learning. Apply by March 15, 2024 https://t.co/un6PKAfkhr

[Elías Rafn Heimisson @EliasHeimisson]

Oh no! It appears that the magmatic dike extends underneath the lava-protection barriers and is feeding a small fissure eruption at the edge of town. Hopefully, the eruption will slow down and concentrate more centrally away from town.

The lava is flowing alongside a barrier that was being created precisely for this purpose to divert the flow away from the greenhouse. The question is if it will hold or the lava will break through or get around.

[Elías Rafn Heimisson @EliasHeimisson]

I started my faculty job at @uni_iceland in geophysics a few days ago. This morning, I could literally see a volcanic plume from the south end of campus!

[Elías Rafn Heimisson @EliasHeimisson]

Although fascinating, the situation is quite serious with infrastructure and houses at risk. We can see on this webcam the lava flowing very close to a large greenhouse. At the current time man-made barriers seem to be diverting the flow https://t.co/EnX5WF85WT

[Dr Tom Winder @twinderseis]

We had a great run, but alas, one of our seismic stations was consumed by lava this morning.

Quite sad watching the waveforms first showing signs of impending lava doom, and then losing contact altogether.

RIP! 🌋☠️🔥
