An interesting paper has just been published in the journal Science, (Cook et al. 2021), which looks at the seismic signals generated by the Chamoli rockslide and debris flow. It concludes that the event was fully detectable by seismic instruments located at up to 100 km from the event.

Arequipa, Peru: landslides triggered by a M=5.6 earthquake on 16 December 2020 have been caught on a dramatic video

Two researchers propose that rocks colliding inside a fault zone as an earthquake happens are the main generators of high-frequency vibrations. That’s a very different explanation than the traditional one, they say, and it could help explain puzzling seismic patterns made by some earthquakes. It could also help scientists predict which faults are likely to produce the more damaging quakes.

In 2017, Evgeny Podolskiy spent more than a week trekking through the Nepalese Himalayas to test the seismic activity of the Trakarding-Trambau Glacier system. In October, the research team and a group of sherpas and porters traveled to an open, debris-free glacier about five kilometers (3.1 miles) above sea level, in full view of Mount Everest.
