I also derived a new elevation model from the aerial images, allowing me to visualize the elevation change in the affected areas. The rocks and debris in the valley are locally up to 32m thick and I estimate the total displaced volume is about 11 million cubic meters.

Very (very) rough analysis indicates >6 m of slip. I resolve pixel offset using DIC in experimental cm sized samples with speckle pattern, and never used it before on satellite images. However the dextral offset is pretty clear, and I trust my calibration so the slip magnitude should be about right.

Looking at the historical earthquake map and the preliminary USGS slip model below, it seems today's large earthquake filled partly the gap between 20 and 22 degrees North latitude.

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.

Experts interpret the

earthquake swarm to be primarly caused by tectonic processes. One of the attributes to distinguish earthquakes associated with volcanisms from these tectonic processes is the distribution of earthquake magnitudes. (1/6)
