Researchers use high-resolution images to create model that predicts landslide risk in coastal areas

São Sebastião, a municipality on the coast of São Paulo state in Brazil that was partially cut off from the rest of the country in February 2023 after a period of torrential rain, had more than 1,000 landslide points, according to an inventory produced by researchers at the University of São Paulo's Institute of Astronomy, Geophysics and Atmospheric Sciences (IAG-USP) and Institute of Geosciences (IGc-USP) using aerial images collected shortly after the disaster.
