The development of robust and transportable models requires access to numerous inventories of ground failure triggered by earthquakes that span a broad range of terrains, shaking characteristics, and climates. We present an openly accessible, centralized earthquake-triggered ground-failure inventory repository in the form of a ScienceBase Community to provide open access to these data, and help accelerate progress. The Community hosts digital inventories created by both USGS and non-USGS authors. We present the original digital inventory files (when available) as well as an integrated database with uniform attributes. We also summarize the mapping methodology and level of completeness as reported by the original authors for each inventory. Contact gs-haz_groundfailure@usgs.gov for more information on how to contribute inventories to this effort. Some inventories are available as seperate shapefile downloads on their corresponding event pages if the primary publication link does not contain the data whereas others may just contain links to the original data from their primary publications.

Earthquake-Triggered Ground Failure associated with the M7.1 2018 Southcentral, Alaska Earthquake
The November 30, 2018, magnitude (Mw) 7.1 Anchorage, Alaska earthquake triggered substantial ground failure throughout Anchorage and surrounding areas (Grant et al., 2020; Jibson et al., 2020). The earthquake was an intraslab event with a focal depth of about 47 km and an epicenter about 16 km north of the city of Anchorage. Peak ground accelerations reached ∼30% g. Despite the relatively low seveAn Open Repository of Earthquake-Triggered Ground-Failure Inventories
