A tool for exploring official decisions
CATNAT.
From places to decisions.
Explore official natural-disaster recognition decisions, find a municipality and understand the context of a publication.
The clay shrink–swell map shows the latest national publication. A municipality’s absence from that publication does not mean its application was refused.
Nicolas Le Corvec · Geoscientist and data scientist
Connect observations
with mechanisms.
My work began with volcanoes: understanding deformation, fractures and magma pathways. It developed through international research, physical modelling and geospatial data analysis.
Three years as a geotechnical expert investigating drought damage caused by clay shrink–swell brought that work into the field. This experience informs my work with fiñv today: combining satellite imagery, geology and climate to understand ground motion, water and natural hazards, then making the results clear and useful.
