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.

NEW: Magma is a furious mixture of molten rock, crystals and gases. It normally makes lots of noise—but, in 2022, a huge volume of magma snuck up on an island in the Azores without making a sound. Yep: magma has a stealth mode. Me @sciam.bsky.social www.scientificamerican.com/article/a-vo...

A volcanic mystery reveals that rising magma has a stealth mode

In 2022 a swarm of earthquakes in the Azores suggested that an eruption was imminent, but none happened. Now we know why, and it means magma can be sneakier than we knew

New! We study the disruptive 2025 earthquake unrest near #Santorini using machine-learning derived seismicity as virtual stress meters at depth. We show the unrest was due to a magma dike intrusion, imaging in detail a complex, rebounding process of dike propagation. www.science.org/doi/10.1126/...

A longer sonification with slower sound rate factor (1000) gives a clearer and more detailed impression of the evolution of the "drumbeat" seismicity, which continues with increasing frequency right up to the largeest (landslide failure?) signal, but not after.

Body waves visible up to 90°, and surface waves beyond. Record section of Z-component seismic recordings from GSN stations filtered between 25 & 100 s 👇

Crazy (horizontal) runup from the large landslide into Tracy Arm fjord, SE Alaska. This is 20 km out the fjord and the wave reached up to 400 m into this side valley. notice how the vegetation was only wetted for the most part (pixels still red) and only the mouth of the river is destroyed.

M6.9 strike-slip quake just now on the active transform fault part of the Charlie Gibbs fracture zone in the N. Atlantic. M~7 is the typical max magnitude of ocean transform events. The active Charlie-Gibbs fault is ~150 km long - a decent portion likely ruptured. earthquake.usgs.gov/earthquakes/...

The descending interferogram from Sentinel-1 (20250319-20250331) suggests that the earthquake rupture extends to 18.7 degrees and may have reached further south. More data in the next few days will reveal the full length of the rupture from this devastating earthquake.

Genuine question: given US isolationism policies right now, can we trust that archived seismology datasets and critical realtime data streams at the EarthScope (IRIS) Data Center (NSF funded) are going to stay accessible to international scientists in the not too distant future?

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.

The modellers among us worked hard to relate the period of the seismic oscillations to the period of a possible seiche (sloshing wave) in the fjord. Could it be modelled? (Yes!) Could it be sustained? (Yes!) @seismo-steve.bsky.social made this awesome video showing our colleagues' efforts!
