Hazards

We make detailed seafloor maps of offshore geology to identify faults and underwater landslides that may cause tsunamis. We develop computer models of shoreline change and sea-level rise. Powerful storms can destroy critical infrastructure and coral reefs that provide protective coastal barriers. Our science helps vulnerable coastal communities develop strategies to become more resilient.

Seeking the Seeps

From June 12 to July 3, 2019, the USGS sailed onboard Schmidt Ocean Institute’s R/V Falkor with several other partners, seeking methane seeps along the seafloor of several underwater canyons off the coast of Oregon and Washington. On this cruise, USGS scientists will seek to understand how much methane is coming out of these seeps, how it travels through the water column, and its ultimate fate in...

Using Video Imagery to Study Coastal Change: Barter Island, Alaska

For a short study period, two video cameras overlooked the coast from atop the coastal bluff of Barter Island in northern Alaska. The purpose was to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.

The Mud Creek landslide on California’s Big Sur coast

On May 20, 2017 , the steep slopes at Mud Creek on California’s Big Sur coast, about 140 miles south of San Francisco, suffered a catastrophic collapse. USGS Scientists from the Pacific Coastal and Marine and the Geology, Minerals, Energy, and Geophysics Science Centers are monitoring this section of the coastline, in collaboration with the California Department of Transportation.
