This inventory was originally created by Townsend and others (2020) describing the landslides triggered by the M 6.7 Northridge, California earthquake that occurred on 17 January 1994 at 12:30:55 UTC. The primary goals of this re-mapping effort were to reduce amalgamation of multiple landslides in a single polygon, relocate misplaced landslides, and to remove large landslide polygons that contained a mixture of disturbed and undisturbed areas. Please see Townsend et al. (2020) for detailed methods.Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory also could be associated with other earthquakes such as aftershocks or triggered events. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use.
With the exception of the data from USGS sources, the inventory data and associated metadata were not acquired by the U.S. Geological Survey (USGS) and thus have not been reviewed for accuracy and completeness by the USGS. They are presented as part of this data series for convenience of the user only, as part of an effort to make published ground-failure inventories more accessible from a single aggregated site.
