Oblique aerial photography and videography of the August 10, 2025 Tracy Arm landslide and tsunami, southeast Alaska Oblique aerial photography and videography of the August 10, 2025 Tracy Arm landslide and tsunami, southeast Alaska
On 10 August 2025, a landslide in Tracy Arm, southeast Alaska, approximately 95 km southeast of Juneau, generated a tsunami with regional effects. Because of poor weather, low visibility, and inaccessible conditions in the water, little was immediately known about the landslide or the total extent and magnitude of the tsunami. On Wednesday, 13 August 2025, USGS scientists Cyrus Read and...
Meteorological Data for Grand Falls Dune Field, Arizona from 2009-2014 (ver. 1.1, December 2025) Meteorological Data for Grand Falls Dune Field, Arizona from 2009-2014 (ver. 1.1, December 2025)
Grand Falls Dune Field (GFDF) on the Navajo Nation (70 km NE of Flagstaff, AZ) is an active, bimodal dune system in both grain size and composition. Felsic grains derive from the Little Colorado River, while mafic (basaltic) grains are sourced locally from nearby cinder cones, making GFDF an excellent terrestrial analog for dune fields on Mars, Venus, and Titan. A long‑term...
Inputs and selected outputs used to assess a stream restoration in Flatlick Branch, Fairfax County, Virginia from water year 2008 through 2024 Inputs and selected outputs used to assess a stream restoration in Flatlick Branch, Fairfax County, Virginia from water year 2008 through 2024
Metrics describing watershed hydrology, stream hydraulics, stream geomorphology, physicochemical processes, and aquatic biology were used to assess a 1.72 km reach of stream above the U.S. Geological Surveys (USGS) Flatlick Branch (station ID 01656903) monitoring station restored using natural channel design. The monitoring station has been continually operated since the start of water...

Rock mass quality and structural geology observations in Prince William Sound, Alaska (2024) Rock mass quality and structural geology observations in Prince William Sound, Alaska (2024)
Multiple subaerial landslides adjacent to Prince William Sound, Alaska (for example, Dai and others, 2020; Higman and others, 2023; Schaefer and others, 2024) pose a threat to the public because of their potential to generate ocean waves (Barnhart and others, 2021, 2022; Dai and others, 2020) that could affect towns and marine activities. One bedrock landslide on the west side of Barry...
