Magma displacement triggered tens of thousands of earthquakes Magma displacement triggered tens of thousands of earthquakes: Analysis of the swarm of earthquakes around Santorini in early 2025 reveals causes and development of the seismic crisis

Our latest study in Nature, together with colleagues from @geomarkiel.bsky.social and universities from Greece, shows what happened beneath Santorini earlier this year when tens of thousands earthquakes shook the islands and the seafloor. It was magma. We also have 1/2

This is one of the most interesting sequences I've worked on so far! It's great to see how machine learning can provide us with these detailed images of seismicity in near real time. I'm glad to have been able to contribute to this project.

Release SeisBench v0.10 - SkyNet, SeisDAE and a more powerful model API · seisbench/seisbench Major updates The SkyNet model is now available in SeisBench. SkyNet is specifically designed to pick phase arrivals at regional distances (up to 20 degree) and also comes with a set of weights to...

SeisBench v.10 is out and it's time for some new models:
- SkyNet allows picking regional phases and can even distinguish Pn, Pg, Sn, Sg (beware of the Terminator though)
- SeisDAE brings easily retrainable seismic waveform denoising

Check out all changes here:
github.com/seisbench/se...

In addition, there are many smaller tweaks (pick export to Pandas, PhaseNetWC, ...). Thanks to all contributors of this release.

You're working on machine learning for seismology as well? SeisBench is always looking for new contributions!

Release SeisBench v0.9 - Two new datasets, pick exporting, lots of small tweaks · seisbench/seisbench Major updates Two new datasets: CWA for Taiwan, containing lots of larger events, and CEED for California, combining millions of manual phase picks with rich metadata from Northern and Southern Ca...

SeisBench v0.9 is out now. Some highlights of the new version:

- The CWA dataset with broadband and strong motion data from Taiwan.
- The CEED dataset covering more than 4 million waveforms from California.
- A 20% speed-up when picking continuous datasets.

The migrations hint at the processes causing SSE initiation on the plate interface. Looking back in time, we identify numerous seismic swarms exactly colocated with the 2023 swarm, suggesting the existence of recurring SSEs in the area. (2/2)

Overview figure of the 2023 SSE with three subplots. Left: The SSE slip model with seismicity overlain. Top right: zoom in on the onset sequence in map view. Bottom right: Cross-section of the onset sequence. In all panels, events are colored by time, revealing clear migtations.

Have you ever wondered how seismic swarms around slow slip events (SSEs) might work? In our recent work, we study the complex seismic migrations around the onset of a shallow SSEs in the Copiapó ridge in 2023. (1/2)

Looking forward to a week full of science and networking at #EGU25! Join my talk on Thursday afternoon if you want to learn about the seismicity in Northern Chile and how swarms reveal the mechanisms of slow slip.

This animation shows an example of how QSeek helps understanding the ongoing Santorini sequence in real-time: bsky.app/profile/gfz....

Our paper on QSeek is out in Seismica now. QSeek detects earthquakes and locates them precisely by backprojecting deep learning phase probability curves in time and space. And that at a blazingly fast speed! Thanks Marius Isken for this great work!

Just to clarify, I didn't make this animation. I made a similar one a few days ago: bsky.app/profile/jann...

Nonetheless, I fully agree that we need solid science funding to enable understanding hazards like this!

The main DEI page from @agu.org has been modified to take diversity out of the title. Glad to see it's not deleted entirely, but hey AGU, we're watching what you do and remembering the big game you once talked about supporting your diverse membership.

Thanks! I've personally left Twitter, but you can share the material there. Please include the link back to the original Bluesky post.

Earthquake activity over distance along the transect. Both the large-scale migration and fine-scale burst migrations in both directions are visible.

Here you go! I picked a few of the burst migration speeds by hand and they are in the range of 2 km/h.

Hi Seismo-Bluesky! I decided to test a pipeline with SeisBench, PyOcto, NonLinLoc, and HypoDD on the Santorini sequence. The level of activity (>4,500 events) is truly stunning! There are repeated bursts migrating backwards and forwards, spreading outwards from a narrow, almost linear channel.

Great idea! Could you add me too?

Huge relief with the French election results! Really happy that I will not be living under a far-right government!

Low-frequency earthquakes are essential markers for understanding slow fault deformation.

Can we automatically detect them?

@jannesmunch.bsky.social et al. can, using their novel deep-learning detector that does not require prior knowledge of the region:
