Introduction This data release is a compilation of known mass movements that generated seismic signals recorded by seismic networks. It represents a major update of a previous data release (Allstadt and others, 2017) available at https://doi.org/10.5066/F7251H3W. This update includes all events published in the previous data release along with more instances of landslides, debris flows, snow avalanches, outburst floods, and lahars, as well as new event types including mine collapses, a submarine landslide, a volcanic flank collapse, and a pyroclastic density current. The 2017 release included only mass movements in the western United States and Canada. The current data release adds new events in North America, and...

We present a preliminary point inventory of the landslides associated with the M7.2 Nippes, Haiti, earthquake that occurred on August 14, 2021. The mapping was part of rapid response efforts to identify hazards for situational awareness and emergency response by humanitarian aid organizations. This inventory accompanies an Open-File Report detailing the hazards presented by the landslides triggered by the earthquake (Martinez et al., 2021). To map the landslides, we used mid- to high-resolution satellite imagery including Sentinel-2 (10-m resolution), WorldView (0.3-0.5-m resolution), Planet (2.7-4.0-m resolution), as well as a high-resolution (1.5 m) Digital Elevation Model (DEM) that was derived from lidar collected...

This dataset contains a point cloud (HalletPeak_PointCloud.las), digital elevation model (HalletPeak_DEM.tif), and orthoimagery (HalletPeak_Ortho.tif) of a debris slide originating on the southeast flank of Hallett Peak and sliding into Upper Chaos Canyon in Rocky Mountain National Park, Colorado, USA. The slide occurred on 28 June 2022, and imagery was obtained on 15 July 2022. These products were created from 692 georeferenced photos, included with this data release (UAV_photos_video.zip), taken from a USGS-approved DJI Mavic Pro uncrewed aerial vehicle (UAV). The photos were converted to a point cloud using the structure from motion (SfM) algorithms in Agisoft Metashape (v. 1.8.3). This debris slide is within...
