Landslides generate seismic waves, as previous measurements from seismometers placed near unstable slopes have shown. However, the analysis of these waves remains a challenge, partly due to the diversity of seismic signals and nomenclatures adopted. Researchers from various laboratories have compiled and analysed observations of several landslides around the world using the mobile park SISMOB of RESIF, in order to propose the first general classification of these sources and their seismic (...)

Hugo Sanchez-Reyes, received the prestigious Outstanding Student Presentation Award (OSPA) for his presentation "An evolutive linear kinematic source inversion" at AGU 2018 Fall Meeting.
The goal of his PhD thesis is to develop a Full Waveform Inversion (FWI) technique combined with the adjoint-state method, often used for imaging the Earth structure, to generate high-resolution kinematic models of earthquake sources in three dimensions (3-D). He is also interested in HPC, inversion (...)

An earthquake of magnitude 2.5 on the Richter scale was recorded on Wednesday evening, January 23rd in the region of Chamrousse and Livet-et-Gavet. The earthquake was recorded at 22:56 by the stations of SISMalp. Its epicentre is located a few kilometres north of Livet-et-Gavet. The phenomenon was felt by the population of the sectors of Vizille, Séchilienne, Chamrousse, but also in Uriage, Brié-et-Angonnes and Eybens. However, no damage was reported. ***The press talks about it

A team involving researchers from six French laboratories, including the Institute of Earth Sciences, has been reconstructing the history of East Antarctica’s erosion for 350 million years (Ma). This study shows that Antarctic erosion is essentially very old, dating back to the Late Paleozoic Ice Age (LPIA), a major glaciation period dated 340-300 Ma. The relief is essentially inherited from this period, while the Antarctic ice cap has had little impact on erosion over the last 30 Ma. (...)

The abundance of titanium dioxide nanoparticles in the environment originating from human activities could be a potential environmental problem. To identify and distinguish between titanium dioxide nanoparticles from natural and anthropogenic sources, synchrotron techniques were used to study the nanoparticles in sewage sludge and soil.
Titanium dioxide nanoparticles are one of the most commonly produced nanomaterials worldwide. They are present in many consumer products, such as (...)

A 3.9 Mw earthquake occurred on Wednesday, November 21, 2018 at around 6pm in the Bourg-en-Bresse region (about 15 km to the west). Located at a depth of about 14 km, it has been widely felt in the region, with more than 1500 testimonies received via the website of the French Central Seismological Bureau. This earthquake was mainly felt as an explosion and a short and intense vibration in the Ain but also in the Rhône, Savoie and Haute-Savoie.
The nearest stations indicate accelerations of (...)
