PSF TelRisNat (2023-2025)

The aim of this project is to provide the theoretical foundations, practical tools and technical support needed to use remote sensing data (satellite, aerial or UAV data) to manage natural hazards (earthquakes, volcanoes, landslides, glaciers, etc.).

The last two decades have seen a boom in remote sensing data, which provides precise information with good spatial resolution and temporal frequency over the entire surface of the planet. Various programmes (Copernicus, USGS-EarthExplorer, PlanetScope, etc.) enable the automatic and global acquisition of a large amount of satellite data, available to everyone in near-real time. These data have led to significant advances in our understanding of the dynamics of the Earth's lithosphere, providing rapid and unprecedented information on recent or ongoing events (earthquakes, landslides, etc.), making it possible to monitor the evolution of glaciers impacted by climate change and also to identify precursors of volcanic and gravity activity. Their role in the prevention and management of natural hazards is growing and complements field data.

However, these new data are still largely underused, particularly by our partners in the South. One obvious reason for this is the lack of training for staff working in local Earth Sciences organisations. Methods for processing and exploiting radar or optical time series are evolving rapidly and there is no academic training in this field in South America.

Objectives :

The PSF TelRiSNat will make it possible to

•  meet strong demand from our partners in Latin America for satellite data processing and analysis for the study of natural hazards,
• coordinate all the training activities in the Andes of the ISDéform National Observation Service, which is responsible for monitoring the movement of the Earth's surface using optical and radar satellite imagery.
• enrich the educational content offered by the SNO with examples from the Andes, thereby enhancing the work of our partners. It will serve as a proof of concept and educational basis for future SNO training initiatives in the South.

Resources :

• the ORISAT MOOC in French, English and Spanish on FunMOOC (first release planned for October 2023)
• face-to-face course sessions with our partners, such as the two courses held in Peru in 2022: "Optical image correlation for landslide detection and monitoring" in August 2022 at INGEMMET and "Course on the use of SAR data for volcano monitoring" organised from 7 to 11 November 2022 at IGP, Arequipa.
