Global Landslide Catalog Aids View From Space
Thursday, April 23, 2015
Landslides are among the most common and dramatic natural hazards, reshaping landscapes and anything in their path. Tracking when and where landslides occur worldwide has historically been difficult, because of the lack of a centralized database across all nations. But NASA researchers have updated the first publicly available Global Landslide Catalog, based on media reports and online databases that bring together many sources of information on landslides that have occurred since 2007. The catalog, originally released in 2010, is still the only one of its kind.
Around 6000 landslides are noted in the catalog. This wealth of data gives scientists a starting point to analyze where, how and why landslides are likely to occur. In particular, NASA researchers have begun to compare landslide occurrence with global rainfall data from the Tropical Rainfall Measuring Mission.

NASA scientists have updated the first publicly available catalog of global rainfall-triggered landslides. The catalog was originally released in 2010 and is still the only one of its kind.
Using the Global Landslide Catalog, a map has been produced to show the location of 5741 rainfall-triggered landslides from 2007-2013.
