Landslides
Landslides are one of the most pervasive hazards in the world, resulting in more fatalities and economic damage than is generally recognized. Every year they block roads, damage infrastructure, and cause thousands of fatalities. Intense and prolonged rainfall is the most frequent landslide trigger around the world, but earthquakes and human influence can also cause significant and widespread landsliding. Using satellite data, we can identify the conditions under which landslides typically occur, helping to improve monitoring and modeling of these hazards
Rainfall Triggered Landslides
Researchers need accurate and timely rainfall information to better understand and model where and when severe floods, frequent landslides and devastating droughts may occur. GPM's global rainfall data will help to better prepare and respond to a wide range of natural disasters.

Modeling and Reporting Landslides
The global Landslide Hazard Assessment for Situational Awareness (LHASA) model was developed to provide situational awareness of landslide hazards for a wide range of users. The model combines TRMM and GPM near real-time precipitation data with a global landslide susceptibility map to generate estimates of where and when rainfall-triggered landslides are likely to occur around the world. Information on landslide reports is available on the Cooperative Open Online Landslide Repository (COOLR), which combines data from NASA's Global Landslide Catalog, other landslide inventories and contributions from citizen scientists via the Landslide Reporter Application.
