A union of LiDAR inventories and InSAR: Distribution and activity of landslides in Yellowstone

Landslide inventories are critical data sets for assessing landslide hazards and understanding landscape evolution. Here we use park-wide LiDAR collected in 2020 to create a landslide inventory and InSAR data to create a time series of landslide activity between 2017 and 2021. We manually mapped and classified ~1800 deposits from LiDAR, ~200 of which present InSAR-detectable movement. In this talk, I will discuss our methods and the overall characteristics of landslides in Yellowstone, share InSAR observations, and highlight some of the myriad opportunities to build on this work.
