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.

Using Video Imagery to Study Coastal Change: Whidbey Island
From May of 2018 through November of 2019, USGS scientists collected imagery from video cameras overlooking the coast along a beach on Whidbey Island, Island County at the northern boundary of Puget Sound in western Washington.
Tsunami Field Studies
Our tsunami scientists work on international teams to study the aftermath of tsunamis around the world, to gain a better understanding the impact of potential tsunamis on coastal communities of the United States. Their work helps inform local, state, and federal coastal planning, protection, and resiliency.
CoSMoS 3.1: Central California
CoSMoS v3.1 for central California shows projections for future climate scenarios (sea-level rise and storms)
Using Video Imagery to Study Wave Dynamics: Isla Verde
USGS scientists installed video cameras atop a building and oceanographic instruments off San Juan, Puerto Rico, to better understand how waves move across coral reefs and cause flooding on tropical shorelines.
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...

Landslide-Induced Tsunamis of Southern Alaska
Working with partners to study and inform the Nation about geohazard risks
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.
