America’s West Coast in July 2018 are associated with low fatalities and consistent with a history of non-fatal landslides.

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.For complete transcript, click here. || 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.The catalog is currently available at: http://ojo-streamer.herokuapp.com/.Research: Spatial and temporal analysis of a global landslide catalog.Journal: Geomorphology, March 21, 2015.Link to paper: http://www.sciencedirect.com/science/article/pii/S0169555X15001579.Here is the YouTube video. || Using the Global Landslide Catalog, a map has been produced to show the location of 5741 rainfall-triggered landslides from 2007-2013. || Using the Global Landslide Catalog, a map has been produced to show the distribution and number of fatallities associated with 5741 rainfall-triggered landslides from 2007-2013. || Using the Global Landslide Catalog, a map, including a legend, has been produced to show the distribution and number of fatallities associated with 5741 rainfall-triggered landslides from 2007-2013. || This is a legend that accompanies the map that shows the distribution and number of fatallities associated with rainfall-triggered landslides in the Global Landslide Catalog.
