The Global Landslide Hazard Map presents a qualitative representation of global landslide hazard at a global scale. It is the combination of the The Global Landslide Hazard Map: Median Annual Rainfall-Triggered Landslide Hazard (1980-2018) and The Global Landslide Hazard Map: Earthquake-Triggered Landslide Hazard which has then been simplified to four categories, ranging from Very low to High landslide hazard, based on the existing system used by ThinkHazard!
information pertaining to earth sciences. Examples: geophysical features and processes, geology, minerals, sciences dealing with the composition, structure and origin of the earth s rocks, risks of earthquakes, volcanic activity, landslides, gravity information, soils, permafrost, hydrogeology, erosion
This project provides a systematic assessment of landslide hazard at a global scale. Landslides triggered by precipitation and landslides triggered by earthquakes have been determined separately and a combined qualitative landslide hazard assessment provided. The intention is that this landslide hazard information can be made available via the Think Hazard! online tool of the GFDRR and The World Bank so that decision makers can access this data to inform disaster risk management.

Data Quality
High-resolution model validated over available observations. Overall good scientific quality.
Supplemental Information
This project defines landslide hazard as the average annual frequency of occurrence of a significant landslide occurring within a defined area. The average time interval between each landslide event, or the recurrence interval (e.g. 1 in 100 years), is the inverse of the average annual frequency (e.g. 0.01). The landslide hazard calculations have been undertaken at a 1 sq. km grid globally and aggregated to different administration unit levels for summary and discussion purposes as required.
