Dreadful scenes from the devastating Rasuwa flood in Nepal/Tibet. My heart goes out to everyone affected. It likely began with a glacier collapse / rock–ice avalanche recorded by seismometers worldwide. I hope real-time seismic monitoring can support early warning for communities downstream.

⚒️ 🧪 A M6.8 earthquake struck Kyushu, Japan today. Large quakes in Japan are common and often pass without much notice, but this one is serious - instead of occurring offshore in the subduction zone, it is a shallow, strike-slip event near Kumamoto. Damage and deaths have already been reported.

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. #Blatten

Map of the Lötschtal showing the area affected by the glacier collapse.
Blue colors show lost elevation, red areas elevation gains.
The two most notable areas are the collapsed peak of Kleines Nesthorn and the collapsed glacier which are shown in deep blue with elevation loss of up to 128m and 51m respectively.
The material slid down the mountain in an approximately 400m wide path and accumulated in a 2,5km long area on the valley floor which is up to 32m thick.
The newly formed lake above the village of Blatten is also drawn in.

The Map text reads:
Kleines Nesthorn and Birchgletscher collapse / Blatten im Lötschental (VS)
On Wednesday, May 28th, a2025, the Birchgletscher glacier collapsed under the weight of rock and debris following the partial collapse of the Kleines Nesthorn.
Approximately 10 million cubic meters of debris flowed into the valley, burying large parts of the villages of Blatten and Ried. The debris also blocked the Lonza River, forming a small lake that destroyed several more houses in Blatten.
Analyis
Using Oblique imagery collected and provided by swisstopo on May 30th, 2025, a photogrammetric DEM was created and compared to the swissALTI3D DEM.

The following volume change was measured in the affected area:

Below Volume (m³): 10.1 Mio

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.

Heat map of N-S displacement at Sagaing, Myanmar, before and after the March 2025 earthquake. The right east (right) side was displaced northward by about 2 m while the west side was displaced southward by about 4.5 m, indicating 6.5 m of N-S slip along a rupture that bisects the city.

Yes, it means a relative abundance of small earthquakes respect to large ones, which might be interpreted as external forcing (e.g., fluids). But a finer analysis is needed, separating the different sub-clusters that compose the seismic sequence.

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.

Claudio Satriano @claudio.seismicsource.org · 10/02/2025

Thanks for the references! I’m currently computing moment magnitudes to better picture the G-R plot (and look at stress drops 😉). For me another possibility of the relative abundance of smaller earthquakes is external forcing (eg. fluids)

Claudio Satriano @claudio.seismicsource.org · 10/02/2025

So the b-value is slightly smaller than one for 3<M<4 and larger than one for M>4. (Caveat: those are local magnitudes). Do you have an interpretation for that?
