Cascadia Subduction Zone Marine Geohazards

Societal Issue: Uncertainty related to rupture extent, slip distribution, and recurrence of past subduction megathrust earthquakes in the Pacific Northwest (northern CA, OR, WA, and southern BC) leads to ambiguity in earthquake and tsunami hazard assessments and hinders our ability to prepare for future events.

USGS Scientists in Samoa and American Samoa Studying Impacts of Tsunami in 2009

On September 29, 2009, an M 8.1 earthquake in the Samoa Islands region of the South Pacific Ocean caused a tsunami that resulted in 100's of lost lives. A rapid-response team of USGS scientists traveled to the Samoa Islands in October-November 2009 to collect time-sensitive data that would have been quickly...

Climate Change and Land-use Histories

We are developing new and unique oceanographic and environmental archives from coral skeleton records to better understand the compounding effects of land-use and environmental change on coral reef health.

Hydrogeology and Reef Health

We are conducting geophysical and geochemical research to address questions about coastal groundwater-to-reef flow and coral reef health, with the goal of informing management decisions related to planning and implementing activities in priority watershed-coral reef systems.

Role of Reefs in Coastal Protection

We are combining ocean, engineering, ecologic, social, and economic modeling to provide a high-resolution, rigorous, spatially-explicit valuation of the coastal flood protection benefits provided by coral reefs and the cost effectiveness of reef restoration for enhancing those benefits.

Reef Resource Assessments - Planning for the Future

We are mapping and assessing all of the important geologic and oceanographic factors to identify those coral reefs most at risk and those reefs that are potentially the most resilient and the most likely to recover from natural and human-driven impacts.

Coastal Habitats in Puget Sound

A Pacific Northwest icon, Puget Sound is the second-largest estuary in the United States. Its unique geology, climate, and nutrient-rich waters produce and sustain biologically productive coastal habitats. These same natural characteristics also contribute to a high quality of life that has led to growth in human population and urbanization. This growth has played a role in degrading the Sound...

COAWST: A Coupled-Ocean-Atmosphere-Wave-Sediment Transport Modeling System

Understanding the processes responsible for coastal change is important for managing both our natural and economic coastal resources. Storms are one of the primary driving forces causing coastal change from a coupling of wave- and wind-driven flows. To better understand storm impacts and their effects on our coastlines, there is an international need to better predict storm paths and...
