Our paper lead by Cameron Spooner (Potsdam) on a 3D gravity-constrained model of the Alps has been published in Solid Earth today. The publication is openly available, together with the model files.

Updated information and figure on the Wildhorn seismic swarm will appear in this post.

Nov. 19. 17h48: Decreasing activity over the past days; many micro-events detected by the SED down to magnitude -2.

Nov. 15. 16h45: No earthquake in the past 24 hours, but it would be too early to say the swarm stopped.

Nov. 13. 09h48: Another slightly felt event yesterday afternoon; the swarm continues.

Nov. 12. 09h32: A new felt event last night, and further smaller events.

Nov. 11. 09h48, 18:23: Small events, not felt by the population, continue to occur.

Nov. 9. 11h30: The sequence continues, without new felt event since the previous update. See SED situation report here.

Nov. 8. 09h24: The sequence continues, with new felt events last night.

An unusual earthquake swarm is ongoing since Tuesday morning, beneath the south flank of Mount Wildhorn and towards the West to Sanetschpass, in the canton of Valais. It is unusual as more than a dozen of felt events have been recorded so far in just two days, amongst over 150 in total. However, the Gutenberg-Richter b-value of the swarm seems to be a common value.

Below is a time evolution figure of the earthquakes and their magnitudes. The released energy overall is equivalent to a magnitude 3.6 earthquake so far. The swarm cannot be considered to be finished as of now. Updates will follow on the SED website as well as here.

The 14th workshop of the International Lithosphere Program‘s Task Force “Sedimentary Basins” takes place in Hévíz, Hungary, from October 15th to 19th. The conference is dedicated to the memory of Frank Horváth, world famous researcher of the Pannonian Basin, who deceased in 2018. For detailed information, please visit the workshop website.

The University of Pavia and a number of collaborating institutions are hosting an international school on the Structure and Composition of the Lower Continental Crust this week. The agenda and the poster abstract book are online; photos and presented slides may come online later.

Our Tectonophysics paper on the “Source mechanism of a lower crust earthquake beneath the Himalayas and its possible relation to metamorphism” is now online, with a FREELY downloadable version until November 12th HERE.

L’exposition inAlpe de l’Université de Lausanne vise à disséminer la culture scientifique dans les Alpes vaudoises. Une partie de l’exposition est installée le long des sentiers de randonnées, et accessible par un code QR dans l’application gratuite Cultural Network.

Une thématique traite les tremblements de terre dans les Alpes vaudoises. Vous pouvez la trouver au panneau 6 près de Leysin (co-ordonnées 567703, 133819), ou en scannant le code QR ci-dessous (et puis, dans une représentation moins jolie, ici).

A 2-year post-doc position is now available in our group, focusing on seismicity and its interpretation deep beneath the Himalayas. The advertisement can be read online and downloaded from here.

Following the successful educational workshop in Pokhara in April, Paul Denton shares his local experience in a lively article on Geoblogy.

The 27th general assembly of International Union of Geodesy and Geophysics (IUGG) took place on 8-18 of this month in Montréal, Canada. Matteo Scarponi and Shiba Subedi from our group have participated in the meeting. This year is the centennial year of IUGG. The next General Assembly will be held in Berlin, Germany, in July 2023.
