Rodrigo De Negri is a geophysicist specialized in remote acoustic sensing of volcanic eruptions and similar energetic phenomena. He uses acoustic signals at frequencies below human hearing (20 Hz), called infrasound, to detect, locate, and characterize volcanic eruptions and other transient natural phenomena at distances up to thousands of kilometers.
Rodrigo is a Ph.D. in Earth Science from the University of California, Santa Barbara (USA), with a M.Sc. in Earth Science from the Autonomous National University of Mexico, as well as a B.Sc. in Physics from the University of Chile. He has worked with the Chilean National Data Centre of the Comprehensive Nuclear-test-ban Organization (CTBTO) and the Seismic Risk Program of the University of Chile (PRS) for the scientific use of the International Monitoring System (IMS) of the CTBTO for volcano monitoring. Previously, he worked at the Laboratoire Magmas et Volcans (France), on the development of the Volcanic Information System, an infrasound-based remote monitoring system for eruptions in the globe that could complement existing satellite-based methodologies.
Rodrigo’s work has been published in several peer-reviewed journals, featuring very energetic eruptions like the 2011 Puyehue-Cordón Caulle and 2015 Calbuco volcanoes in Chile, multi-year eruptions from Yasur and Ambrym volcanoes in the Vanuatu archipelago, as well as previously unobserved eruptive activity at the remote Mount Michael volcano (Saunders Island) in the South Sandwich Islands, southern Atlantic Ocean.
At Â鶹ÊÓƵhe is involved in developing seismo-acoustic as well as infrasound-only monitoring of natural hazards (e.g., rockfalls, avalanches, landslides, etc.) around Mount Meager volcano (British Columbia, Canada). With the Â鶹ÊÓƵPhysical Volcanology Research Group, he helped establish the first dedicated volcano seismo-acoustic monitoring stations around Meager, and is actively involved in the design and testing of the detection algorithms that will be implemented in real-time for the future Meager observatory.
