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.

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.
