The Cascadia Region Earthquake Science Center (CRESCENT) Ground Failure Viewer (v1.0.0)

The CRESCENT Ground Failure Viewer and underlying database are currently prepopulated with curated, open-source landslide inventories from Oregon, Washington, California, and Canada. These foundational datasets provide a harmonized regional baseline and serve as the starting point for an expanding, community-driven collection of landslide and ground-failure inventories across Cascadia and surrounding regions. We have added a series of filters, including shaking intensity metrics, mean annual precipitation, and basic landslide types that allow users to export and download referenced data. The goal of this phase was to get the infrastructure in place for a community-based portal to visualize ground failure data in context of Cascadia, giving users a way to filter and explore the data across the region (From BC to California) in a unified way. Alongside the viewer, we provide a jupyter-book to detail the processing of the available datasets and demonstrate transparently how data has been unified. This Jupyter-Book also serves as community resource to prepare and submit new data to the database. The next goal is to allow members of the Cascadia Ground Failure community to share peer-reviewed datasets through this system, expanding open sharing and analysis of landslides and liquefaction hazards in the region. To facilitate the submission of new data, we also developed a jupyter-book going over the processing of the currently available datasets and guiding users through the steps. We acknowledge the contributions of Kate Mickelson (DNR), Bill Burns (DOGAMI), Margaret Parks (CGS), Marc-André Brideau (BCGS), Alex Grant (USGS), Lydia Staisch (USGS), and Will T. Struble (U Houston) for providing data and comments during the development phase.
