Avec un colloque et une grande couverture médiatique, la série d’événements sur Les séismes de 1946 – Se souvenir pour se préparer au prochain tremblement de terre en Valais débute ce lundi 25 janvier. Découvrez toutes les informations sur le site web!
Here is a nice way of reaching the general public to raise their awareness about natural hazards: with a SONG! The Seismology at School in Nepal program has initiated the idea, and then the Earthquake Awareness Song was written and composed by Shiba Subedi, Pashupati Sharma and Devi Gharti, with a larger team performing the video clip. The song is in Nepali with English subtitles, so everyone can follow.
If you think it is worth supporting the development of the Seismology at School in Nepal program, please visit the crowdfunding campaign site.
Se souvenir pour se préparer au prochain tremblement de terre en Valais – telle est la devise des événements qui auront lieu tout le long de l’année 2021. Le 25 janvier 1946, le Valais était frappé par un grand séisme estimé à une magnitude de 5.8, suivi de répliques. Avec un déroulement en temps similaire 75 années plus tard, le CIRM à l’UNIL et ses partenaires organisent une série d’activités, en allant d’un colloque via une exposition, un jeu de piste, jusqu’à des conférences grand public. Découvrez l’ensemble du programme sur le site web dédié, ou en suivant les hashtags #SeismeVS46 ou #BebenVS46.
Three years ago we started an educational seismology project in Nepal. Based on the success and positive feedback, we now aim to expand the project further across the country. The manpower is secured, yet the funds for new instruments is still lacking. Therefore we are now launching a crowdsourcing campaign to Help Save People in Nepal from Big Earthquakes: please see all details, including a 3-minute video by Shiba Subedi, on this GoFundMe page.
Since Sunday October 25th a series of small earthquakes occurred in the Canton of Glarus, near the village of Elm. The largest event so far was magnitude 4.4, the focal depths are shallow (ca. 1-2 km). So far no damage was reported. Further information and news are available at the Swiss Seismological Service.
The field season is likely finished as the first snow felt the day after this photo was taken…
Together with a group of colleagues with complementary expertise, we present the first modern seismic hazard and risk assessment in the Bhutan Himalaya in form of a paper accepted for publication in Natural Hazards: http://doi.org/10.1007/s11069-020-04275-3.
The results on an interactive map, the raw data and the model (OpenQuake) files are available online HERE.
The “lockdown” lowering the level of environmental ground vibrations has found wide attention already in the Spring in social media and on websites (here is our news). The full scientific treatment with examples from around the world, including our from project in Nepal, is now published in Science:

The summer field season could luckily start!… although the weather conditions are not always ideal. Our gravimeter has also shown in real time the passage of surface waves from a M7.4 earthquake near the antipode.
Less than 3 years after starting new gravimetry surveys in the Ivrea-Verbano Zone to better constrain the 3D geometry of the shallow-lying Ivrea geophysical body, our paper on the results has been just accepted at Geophysical Journal International – see Scarponi et al. (2020): New gravity data and 3D density model constraints on the Ivrea Geophysical Body (Western Alps).
