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. Precipitation is a common trigger of landslides. The Global Precipitation Measurement Mission (GPM) Integrated Multi-satellitE Retrievals for GPM (IMERG) data shows recent precipitation, updated every thirty minutes. A LHASA landslide “nowcast” is created by comparing GPM data from the last seven days to the long-term precipitation record provided by the Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis (TMPA). Because IMERG data was only available starting in 2014, the record of historical rainfall was established by TMPA, comparing 2001-present. The TMPA rainfall probability distributions were then compared to that of IMERG and the rainfall thresholds were adjusted so that the IMERG data more closely mapped to those of the TMPA archive. The past 7 days of rainfall are considered, with each day weighted according to their date before present, with the last twenty-four hours having the most impact.

The landslide susceptibility map was developed to assess the underlying landslide susceptibility of terrain. This includes quantitative information on if roads have been built, trees have been cut down or burned, a major tectonic fault is nearby, the local bedrock is weak, and/or the hillsides are steep. This map was combined with Global Precipitation Measurement (GPM) data to develop the LHASA model.

The NASA Global Landslide Catalog (GLC) is the largest openly available global inventory of rainfall-triggered mass movements known to date. The inventory was created in at NASA Goddard Space Flight Center (GSFC) and currently contains more than 11,500 reports on landslides, debris flows, rock avalanches, etc. around the world. Reports of landslides are found primarily from online media, including news articles as well as other databases. The GLC has been compiled by scientists, interns and other colleagues at NASA GSFC. The GLC has been cited more than 75 times in peer-reviewed articles.
The GLC is a part of the Cooperative Open Online Landslide Repository (COOLR), and can be downloaded on Landslide Viewer. When COOLR is downloaded, GLC data can be found by the label "GLC" in the database field "event_import_source". For referencing the GLC in research, please see the Downloading the Data page.
