Our NASA landslides team has been developing the Landslide Hazard Assessment for Situational Awareness model to provide an indication of where and when landslides may be likely around the world every 30 minutes. The team has also created a Landslide Susceptibility Map and the Global Landslide Catalog, which is the base for COOLR.
