Other ID: none

Status: Completed

Organization(s): USGS, Pacific Coastal and Marine Science Center, USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s): Coastal and marine earthquake, tsunami, and landslide active margin field studies (ZP00EQV)

Principal Investigator(s): Daniel Brothers
