Sublacustrine landslide and tsunami models from Lake Quinault, Washington Sublacustrine landslide and tsunami models from Lake Quinault, Washington
This USGS data release provides model setup files to simulate a hypothetical sublacustrine landslide in Lake Quinault and resulting tsunami waves.
Compositions of ash, soil, sediment, water, and biota after the 2020 CZU Lightning Complex Wildfire, Santa Cruz Mountains, California Compositions of ash, soil, sediment, water, and biota after the 2020 CZU Lightning Complex Wildfire, Santa Cruz Mountains, California
The CZU Lightning Complex Wildfire burned 86,500 acres of forested coastal watersheds in the Santa Cruz Mountains, CA, from August 16 to September 22, 2020. Ash, soil, and stream sediment were collected and characterized as soon as sites could be safely accessed to quantify potential environmental and public hazards from wildfire-related potentially toxic metals and polycyclic aromatic
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, July and August, 2023 Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, July and August, 2023
Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...
CoSMoS (Coastal Storm Modeling System) modeled flood hazards for King County, Washington CoSMoS (Coastal Storm Modeling System) modeled flood hazards for King County, Washington
This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR), projected coastal storms, and streamflow. Products include projected flood depths, flood extents including uncertainties, water elevations, velocity hazards, and flood duration. These are generated using a suite of numerical models driven by outputs from Global Climate Models...

Underwater imagery and classifications of the substrate and coral reef habitat on the Kona coast of the Island of Hawai`i, from 2003, 2004, and 2022 Underwater imagery and classifications of the substrate and coral reef habitat on the Kona coast of the Island of Hawai`i, from 2003, 2004, and 2022
Images of the seafloor off the Kona coast of the Island of Hawai`i were collected by the United States Geological Survey in 2003, 2004, and 2022, during field activities A803HW, A204HW, A604HW, and 2022-615-FA. The images were acquired in cooperation with the National Park Service, primarily in the waters off Kaloko-Honokohau National Historical Park, Pu`ukohola Heiau National Historic...

Bathymetry and acoustic-backscatter data for Lake Sammamish, Washington collected during USGS field activity 2021-656-FA Bathymetry and acoustic-backscatter data for Lake Sammamish, Washington collected during USGS field activity 2021-656-FA
The Pacific Northwest is home to numerous faults that cut through the surrounding crust including the Seattle fault. Over time, frictional stresses accumulate along these faults, building slowly until they exceed the fault's strength, resulting in an earthquake. Evidence of these earthquakes may be found in Pacific Northwest lakes. Past underwater landslides caused by the earthquakes...
