Jean-Robert Grasso : Physicien d’observatoire Classe Exceptionnelle, ISterre

Research interests - Failures and instabilities of the fragile Earth (Earthquake, Volcano eruption, landslide, snow avalanche)
87 publications in peer-reviewed international journals, h (index)= 35 (June 2019)

Jean-Robert Grasso is an Observatory -Physicist, Geophysics, at ISterre-OSUG, University Grenoble Alpes since 1994. He was Director of the Piton de la Fournaise Volcano Observatory, Reunion Island between 1992 and 1994, and visiting scholar at Institute of Geophysics and Planetary Physics, UCLA, USA, 2002-2003, and USGS Menlo Park CA, USA, 2004-2005. Research activities focus on the failures and instabilities in solid Earth, with emphasis on implications for processes and hazard assessments. He mostly used seismic ruptures as gauges of damage processes at different scales before earthquake, volcano eruption and landslide. From dislocations in ice single crystal, icequakes, volcanic seismicity, induced and triggered seismicity to major intraplate M>7 events. He published 87 papers in International Journals (Nature, 2 ; PRL 1 ; GRL 14, JGR 24 in the fields of earthquakes, volcanoes, landslides and snow avalanches). During the last 10 years, he was a local PI of 6 H2020 EC projects and Ph.D. adviser for 4 students.
