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.

New paper alert. Volcanic crisis reveals coupled magma system at Santorini and Kolumbo. Great work led by Marius and Jens, thanks all for working on that together! It can be found in today’s issue of Nature.

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:

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!

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)

Jannes Münchmeyer @jannesmunch.bsky.social · May 8

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.

GFZ Helmholtz-Zentrum für Geoforschung @gfz.bsky.social · Feb 6

Some of you were waiting for it: Here's our new data visualisation of the earthquakes near #Santorini, provided by our colleague Marius Paul Isken, and located with pyrocko/qseek. It includes yesterday's quakes and starts January 29. Marius included a nice twist, so to speak. Wait for it.

Jannes Münchmeyer @jannesmunch.bsky.social · Feb 26

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!

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

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.

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

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