Coastal and Marine Hazards and Resources Program

Hazards

Ocean hazard events, like tsunamis triggered by earthquakes and landslides, storm surges associated with hurricanes and extreme storms, oil and gas spills, and floods and associated watershed contaminants, affect the health and safety of our Nation's ocean and coastal communities and ecosystems. USGS scientists study the causes, distribution, and hazard potential of these events including earthquakes, submarine landslides, and tsunamis; coastal inundation associated with hurricanes, extreme storms, and sea-level rise; and oil and gas spills. USGS also develops computer models and tools that, when combined with our science, help evaluate and forecast coastal hazard probability and occurrence.

Probabilistic Forecasting of Earthquakes, Tsunamis, and Earthquake Effects in the Coastal Zone

The nation's coastlines are vulnerable to the interrelated hazards posed by earthquakes, landslides, and tsunamis. In the marine environment these events often occur in concert, and distant triggers can cause severe local effects, making the issue global in scope. As the population continues to migrate toward the coastlines, the social impacts of these hazards are expected to grow.

Coral Reef Project: Puerto Rico

To better understand how waves move across coral reefs and cause flooding on tropical shorelines, USGS scientists have installed video cameras and oceanographic instruments off San Juan and Rincón, Puerto Rico. Their work is part of a study funded by USGS after Hurricanes Irma and Maria. The offshore instruments measure wave heights and speeds; the onshore video cameras show where waves break...

Coastal System Change at Fire Island, New York

Fire Island is a 50-km long barrier island along the south shore of Long Island, New York. The island is comprised of seventeen year-round communities; federal, state, and county parks; and supports distinct ecosystems alongside areas of economic and cultural value. In addition to providing resources to its residents, the barrier island also protects the heavily-populated mainland from storm...

Coastal Storm Modeling System (CoSMoS)

The Coastal Storm Modeling System (CoSMoS) makes detailed predictions of storm-induced coastal flooding, erosion, and cliff failures over large geographic scales. CoSMoS was developed for hindcast studies, operational applications and future climate scenarios to provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety...

Using Video Imagery to Study Coastal Change: Santa Cruz Beaches

Two video cameras atop the Dream Inn hotel in Santa Cruz, California, overlook the coast in northern Monterey Bay. One camera looks eastward over Santa Cruz Main Beach and boardwalk, while the other looks southward over Cowells Beach. The cameras are part of the Remote Sensing Coastal Change project.

Using Video Imagery to Study Wave Dynamics: Tres Palmas

Four video cameras look westward over the coast and the coral reef at Tres Palmas in Rincón, on the west coast of Puerto Rico. Two cameras look out at the horizon and over the ocean for the mid-field view; one camera offers a zoomed-in, far-field view overlooking the reef and out to the island of Desecheo, a U.S. National Wildlife Refuge; and another camera focuses on the beach.
