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 of USGS field activity K0211PS collected in Puget Sound, Washington in April of 2011 Chirp sub-bottom data of USGS field activity K0211PS collected in Puget Sound, Washington in April of 2011

High-resolution chirp sub-bottom data were collected by the U.S. Geological Survey in April 2011 south of Bainbridge Island and west of Seattle in Puget Sound, Washington. Data were collected aboard the R/V Karluk during field activity K0211PS using an Edgetech SB-512i sub-bottom profiler. Sub-bottom acoustic penetration spans several tens of meters and is variable by location.

Controls on sediment distribution in the coastal zone of the central California transform continental margin, USA Controls on sediment distribution in the coastal zone of the central California transform continental margin, USA

We use >10,000 km of high-resolution seismic-reflection data together with multibeam bathymetry to document complex and highly variable post-Last Glacial Maximum (LGM) sediment distribution and thickness in the coastal zone (~10 m isobath to 5.6 km offshore) along a ~800 km section of central California's transform continental margin. Sediment thickness ranges from 0 (seafloor bedrock)...

Right-lateral fault motion along the slope-basin transition, Gulf of Santa Catalina, southern California Right-lateral fault motion along the slope-basin transition, Gulf of Santa Catalina, southern California

An active fault system carrying a significant component of right-lateral strike-slip motion extends for ~60 km along the slope–basin transition, ~10 to 20 km offshore of the southern California coast from La Jolla to Dana Point. From south to north, this fault system includes the Carlsbad, San Onofre, and San Mateo fault zones. High-resolution single channel minisparker and chirp seismic...
