2022-653-FA (CMHRP activity #9014)

Field Activity 2022-653-FA

Identifier

2022-653-FA

Purpose

To collect sediment cores for marine geohazard studies

Location

Northern California, Oregon, Washington, United States, Pacific Ocean

Summary

Collected piston cores up to 8m-long along deepwater portions of northern CA, OR, and WA. Cruise was cut short due to ship mechanical issues. Did not get deepwater cores in WA. Chirp data were collected along the mid-slope in OR.

Info derived

Sediment age, character and distribution; earthquake recurrence; fault characterization
