Coastal and Marine Geohazards of the U.S. West Coast and Alaska
Coastal and marine geohazards are sudden and extreme events beneath the ocean that threaten coastal populations. These underwater hazards include earthquakes, volcanic eruptions, landslides, and tsunamis. The tectonically active west coast of the Americas is prone to such hazards, as it lies along the boundaries of major tectonic plates that make up the Earth's crust—the North American, Caribbean...

Chirp sub-bottom data collected in the Great Salt Lake, Utah during USGS field activity 2021-615-FA Chirp sub-bottom data collected in the Great Salt Lake, Utah during USGS field activity 2021-615-FA
This data release contains 57 high-resolution chirp sub-bottom profiles collected in the southern Great Salt Lake, Utah, by the U.S. Geological Survey in June 2021 during field activity 2021-615-FA. The dataset was acquired to image subsurface sedimentary structures and stratigraphy in support of efforts to characterize past earthquake events along the Great Salt Lake Fault, contributing...
Sediment core data from offshore Cascadia during field activity 2022-653-FA Sediment core data from offshore Cascadia during field activity 2022-653-FA
This data release contains sediment core data including X-ray Computed Tomography (CT) scans, photos, and multi-sensor core logger (MSCL) data. Sediment cores were collected along the Cascadia Subduction Zone (offshore northern California, Oregon and Washington) during U.S. Geological Survey cruise 2022-653-FA aboard the M/V Bold-Horizon. The cores were collected to evaluate potential...
Seismic sub-bottom, sediment core and radiocarbon data collected in Ozette Lake, Washington from 2019-2021 Seismic sub-bottom, sediment core and radiocarbon data collected in Ozette Lake, Washington from 2019-2021
Seismic-reflection data and cores were collected in Ozette Lake, Washington, from 2019 to 2021. These data were used to investigate submarine landslide deposits triggered by large Cascadia Subduction Zone earthquakes. Identification of fault-related submarine hazards is a primary mission of the USGS Coastal and Marine Geology Program. In the US Pacific Northwest region, the greatest...
Multichannel minisparker and chirp seismic reflection data collected during USGS field activity 2021-614-FA along the Palos Verdes Fault Zone Multichannel minisparker and chirp seismic reflection data collected during USGS field activity 2021-614-FA along the Palos Verdes Fault Zone
High-resolution multichannel seismic (MCS) and coincident Chirp sub-bottom data were acquired during USGS field activity 2021-614-FA aboard the R/V Sproul in May of 2021. The survey was conducted in the offshore region of southern California, specifically in the inner continental borderlands tectonic region. The focus of the survey was to collect seismic lines perpendicular to the Palos...
Chirp sub-bottom data collected in Lake Crescent, Washington during USGS field activity 2019-622-FA Chirp sub-bottom data collected in Lake Crescent, Washington during USGS field activity 2019-622-FA
Chirp sub-botttom data were acquired during USGS field activity 2019-622-FA in August of 2019. The survey was conducted in Lake Crescent, Washington. Geophysical mapping was conducted to investigate earthquake triggered mass transport deposits as part of the Cascaadia Earthquake recurrence project. These data and information are intended for science researchers, students, policy makers...
Reprocessed single channel sparker seismic reflection data offshore central California from USGS field activities S-6-08-SC and S-6-09-SC Reprocessed single channel sparker seismic reflection data offshore central California from USGS field activities S-6-08-SC and S-6-09-SC
The U.S. Geological Survey collected high-resolution single channel minisparker data between Point Sal and Piedras Blancas in 2008 and 2009 with support from the Pacific Gas and Electric (PG&E) CRADA and the USGS Coastal and Marine Geology program. Reprocessing of this data in 2018 improved vertical resolution of the stratigraphy and structural deformation of the original data and was...
