Description:

Abstract:

This dataset includes grain-size data of sediment cores collected offshore central California in the vicinity of Morro Bay. These data were collected aboard the M/V Bold Horizon in October 2019 for use in regional hazard assessments relating to the Hosgri Fault.

Purpose:

Identification of fault-related submarine hazards is a primary mission of the USGS Coastal and Marine Hazards and Resources Program. The Hosgri Fault is a submarine fault system that likely poses the greatest submarine earthquake threat in the central California region. To gain a better understanding of this fault system, the USGS collected sparker multichannel seismic, CHIRP seismic, and sediment cores to enable a detailed investigation of its geologic history and ongoing activity. These data are intended to further our understanding of geologic hazards near the Hosgri Fault, improve risk assessments for local communities and critical infrastructure, and to provide data for future research on regional tectonic, sedimentary, and geomorphic evolution of coastal California. This work was funded through a Cooperative Research and Development Agreement (CRADA) between the USGS and Pacific Gas and Electric Corporation.

Lineage:

Process_Step:

Process_Description:

Cores were collected aboard the M/V Bold Horizon using a Rossfelder P-5 vibracorer during U.S. Geological Survey cruise 2019-651-FA. The cores were transported back to the USGS Pacific Coastal and Marine Science Center core lab for subsequent analyses.

Process_Date: 2019

Process_Step:

Process_Description:

One cubic centimeter core samples were taken at 5 cm intervals in cores HF-01, HF-03, and HF-07. Core HF-05, the longest core, was sampled at 5-cm intervals for the first 105 cm, and then at 2- and 3-cm intervals for the rest of the core. Sediment samples were pre-treated with 30 percent hydrogen peroxide to remove organic materials. Then, sediment was loaded into a CILAS 1190L particle size analyzer with a stated measurement range of 0.04 to 2500 microns.
