A new PhD student joining the group, Nasrin Amini Tehrani

My firstname is Nasrin and I am a Ph.D. student at the University of Lausanne, Switzerland, and study in niche, habitat suitability, and distribution modeling, mainly at the level of species, but also of biodiversity, communities and ecosystems. My projects focus on spatial prediction of essential biodiversity variables (EBVs) for bird species in The Western Swiss Alps that driving the distribution of species and their assemblages, or on more applied aspects, such as climate and land-use changes, and rare and threatened species management.

Visit to Prof. J. Locat at LERN at ULAVAL

From the 9-16 November 2018, M. Jaboyedoff visited at LERN University of Laval Prof Locat, Dr A. Blais-Stevens, Dr C. Cloutier and Dr D. Turmel to focus on our project of book in French about Landslides which will contain approximately 30 authors and have 33 chapters. Two third of the chapter are now written in their first version.  

New visiting PhD student in the group RISK

Chunwei Sun will stay for 2 years in the Risk Group at UNIL. Chunwei is a joint-PhD student of the Department of Geological Engineering of Southwest Jiaotong University in Chengdu, China. His research involves geochemical weathering in rock mass deterioration and the oxidation-acid erosion mechanism of black shale especially. During his stay at UNIL, he will focus on the analysis of fissure water, ion exchange and elements migration processes under water-rock chemical interaction.

Welcome Chunwei!

Journée des Aléas Gravitaires (JAG) 2019

Emmanuel Nduwayezu and François Noël from the group participated to the Journée des Aléas Gravitaires (JAG) in Nice – Sophia-Antipolis on October 8 to 10 2019. It was a great opportunity to exchange about many topics related to natural hazards and rockfalls. Early results from the ongoing analysis of the data from the rockfall experiment performed near Barcelonnette in 2018 were presented:

New PhD student in the group RISK

Tiggi Choanji has started a PhD project  in the group RISK of the Institute of Earth Science (ISTE), University of Lausanne, under the supervision of Prof. Michel Jaboyedoff.  Tiggi holds a master degree in geology from Bandung Institute of Technology (ITB), Indonesia, about the characterization and modelling of sandstone on Central Sumatera.

In Lausanne, Tiggi will work on “The Landslide Identification and Assessment in Areas with Active Movement Plates, Using Satellite Images, Infiltration Analysis and Microstructures Data”.

Welcome to Tiggi

Field work with Prof Masahiro Chigira (DPRI University of Kyoto) and Prof. Satoru Kojima (Gifu University)

It was a great pleasure to spent days of the field with Profs M. Chigira S. Kojima in Septmber 2019. They are now studying the deep-seated gravitational deformation in the Val Bedretto in Ticino. Huge slope deformations are visible in that region. This is the opportunity to compare to other type for such slope movements. The collaboration will continue the next years.

LARAM School at UNIL 2-13 September 2019

We have been very lucky and honoured to host the 15th LARAM school 1st @ UNIL, from 2 to 13 September 2019 on the request of the team of the University of Salerno. We organized this summer school with our PhD students, which brought together around thirty PhD students and post-docs from all over the world. Nearly 30 teachers among the best experts on the landslide risks have taught during these 15 days. It was a great success. 4 PhD of UNIL participated.

Field visit at Chamoson for debris flows

On 11 August 2019, a debris flows stroke the village of Chamoson, in Wallis (Switzerland). One car with two passengers was washed away and disappeared in the debris flows.

On August 30, some members of the group risk went in Chamoson (1) to understand the processes going on in the source area up in the valley and (2) to map with a UAV-LiDAR the deposit zone. Our colleague of geophysics, Ludovic Baron, had been spending several days searching the disappeared car with a magnetometer. However the method proved to be very efficient, the car and its passengers were not found in the inspected area.

The national Swiss television was present and produced a short report of these techniques for the evening news:
