Workshop about Monitoring and characterization tools dedicated to rock instabilities for practitioners in Jura canton: “Outils de surveillance et de caractérisation des instabilités rocheuses”

Les Forges (JU, Switzerland) unstable column (with the road below)

The risk group (C. Lefeuvre, J. Voumard, M.-H. Derron, M. Jaboyedoff) provided a course on 5th May 2017 in the Café de la Poste, Glovelier (JURA) dedicated to “Outils de surveillance et de caractérisation des instabilités rocheuses » (Monitoring and characterization tools dedicated to rock instabilities) organized by the head of natural hazard of the canton du Jura: Dr. Andrea Pedrazzini.

This workshops followed a study performed by our group about a rock slope in limestone of the Jura mountain (see pictures).

Workshop – Drainage of large rockslides – Oslo 30-31th of January 2017

M. Jaboyedoff participated to the Workshop – Drainage of large rockslides in Oslo on 30-31th of January 2017 at The Norwegian Water Resources and Energy Directorate (NVE). He presented: “Structure of the Åknes rock slope – comparable to others sites with drainage?” The goal of this workshop was to discuss the possibility of a drainage of the Åknes rockslide, because this landslide moves and can promote a tsunami if it fails, which will affect a lot of inhabited areas.

By the way, a movie has been done about this specific site: the Wave.

Visite d’une délégation UNIL à ULAVAL en mars 2017

Du 6 au 8 mars 2017 M. Jaboyedoff a été membre d’une délégation de l’UNIL qui a visité l’université LAVAL. A cette occasion des discussions ont été menées pour favoriser les échanges d’étudiants et de chercheurs de la FGSE dans le cadre de l’accord privilégié qui se met ne place entre les deux universités. En 2017, 6 étudiants de la FGSE se rendront à ULAVAL.

On February 21st, Michel Jaboyedoff received the DPRI Award (Disaster Prevention Research Institute – Kyoto University). He expressed his gratitude to DPRI and Prof. Chigira when he received his award. He delivered a Memorial Lecture entitled: “Emerging Techniques and Impact of Human Activities in Landslide Risk Management: 3D Analysis and Human Induced Landslides” (video). The International Institute for Applied Systems Analysis (IIASA) received this award jointly.

Présentation du rapport final du projet ParaChute et de la Méthode d’Évaluation du Danger de Chutes de Pierres (MEDCP)

Le 13 mars 2017, M. Jaboyedoff et F. Noël ont participé à la réunion finale du projet Parachute, via Skype avec ULAVAL. Lobjectif de ce projet était de développer une nouvelle méthode pour évaluer le risque de chutes de blocs le long d’une structure linéaire comme les chemins de fer. Le projet s’est concentré sur une voie ferrée située dans l’est du Québec. Tous deux ont participé à l’élaboration de ce projet. F. Noël y a réalisé son travail de master ( et M. Jaboyedoff a agi comme consultant. Les méthodes développées durant ce projet se sont avérées particulièrement innovantes et originales.

Nous remercions le Prof. J. Locat de nous avoir impliqué dans ce projet très intéressant

Laram School and 8th ALERT Zienkiewicz Course 5th – 16th September 2016, Salerno, Italy

M. Jaboyedoff was invited by Prof. Cascini (University of Salerno) to present on September 12 a half day courses about “Human induced landslides” in the LARAM School 2016 (Landslide Risk Assessment and Mitigation). “The LARAM course is intended for 40 PhD students that are carrying out research in the field of landslide hazard and risk assessment”. The exchange with student were very interesting and enriching. The team of Salerno was very nice and discussion with them were very fruitful. It was a great experience that we will renew in 2017.

3rd Global Summit of Research Institutes for Disaster Risk Reduction: Expanding the Platform for Bridging Science and Policy Making – GADRI – 19 to 21 March 2017

The Faculty of Geosciences and Environment of UNIL is now member of GADRI (Global Alliance of Disaster Research Institutes). M. Jaboyedoff participated to the 3rd Global Summit of Research Institutes for Disaster Risk Reduction: Expanding the Platform for Bridging Science and Policy Making (GSRIDRR 2017) at the Disaster Prevention Research Institute (DPRI), (Kyoto University, Uji Campus, Oubaku Plaza, Kyoto, Japan) – 19 to 21 March 2017. The meeting asked to the participant to present future challenging research topics (program). M. Jaboyedoff gave a talk about: Costal erosion by landsliding.

In memoriam Jacques Bechet

img_9698_2We have recently published two papers written with our former Master’s student Jacques Bechet who died tragically in a snow avalanches on 28 March, 2015. We dedicate these papers to Jacques Bechet (first author). Their content is an expression of his great ingenuity, curiosity and passion for research he shared with his co-worker Julien Duc. We will always remember his enthusiasm and his kindness. We sympathize with his family and with his friend Julien Duc who worked closely with him.

Preferred Partnership “Partenariat privilégié” UNIL-Université LAVAL

In October 2016, M. Jaboyedoff and two colleagues met in University Laval several colleagues of the department of geology and engineering geology and of the faculty of forestry, geography and geomatics. The goal was to explore the possibility of join research in the framework of a collaboration between both UNIL and ULAVAL. Promising exchanges are planned for master students as well for jointed researches especially for an international joint laboratory.

On the 88th Congress of the Italian Geological Society

On Wednesday September 7 2016, M. Jaboyedoff was invited by Prof. G.B. Crosta to present a talk about: “Why do we need conceptual models for landslides?” by Jaboyedoff M., Abellan A., Blikra L., Derron M.-H., Jongmans D. & Locat J. within the session S 27: Mapping, monitoring and modelling: tools for landslide hazard assessment (Conveners and Chairpersons G.B. Crosta, Berti M., De Vita P., Frattini F.). The conceptual models are an important topic, it is fundamental to try to conceptualize methods to obtain such models. The session and discussions were very interesting and the congress very stimulating. Italian scientists are among the most active in landslides science in the world.
