About this dataset

NASA Landslide Hazard Assessment for Situational Awareness — global landslide susceptibility and rainfall-triggered hazard nowcasts.

NASA's LHASA (Landslide Hazard Assessment for Situational Awareness) provides global landslide susceptibility mapping and real-time rainfall-triggered landslide hazard nowcasts. The susceptibility map classifies terrain into five hazard levels from very low to very high using slope, lithology, soil moisture, and land cover factors. Real-time products combine susceptibility with satellite rainfall estimates.

FAQ

What factors determine landslide susceptibility?

LHASA uses slope gradient, lithology (rock type), soil moisture, land cover, and distance to faults to classify terrain into five hazard classes.

Does LHASA provide real-time landslide alerts?

Yes. LHASA combines the susceptibility map with IMERG satellite rainfall estimates to provide real-time (3-hourly) nowcasts of landslide hazard.
