ABSTRACT: In Brazil, the prominent climate-induced disasters
are floods and mass movements, with the latter being the most lethal. The spate
of major landslide events, especially those in 2011, catalyzed the creation of CEMADEN
(National Center for Monitoring and Early Warning of Natural Disasters). This
article introduces one of CEMADEN’s pivotal systems for early landslide warnings and traces its
developmental timeline. The highlighted SNAKE System epitomizes advancements in
digital monitoring, forecasting, and alert mechanisms. By leveraging
precipitation data from pluviometers in observed municipalities, the system bolsters early warnings related to potential
mass movements, like planar slides and debris flows. Its deployment in CEMADEN’s Situation Room attests to
its suitability for overseeing high-risk municipalities, attributed primarily
to its robustness and precision.
