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.

Woods Hole Coastal and Marine Science Center 2020 Annual Report

The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center in Woods Hole, Massachusetts, is one of three centers serving the mission of the USGS Coastal/Marine Hazards and Resources Program (CMHRP). Since its authorization by Congress in 1962, the CMHRP has served as the primary Federal program for marine geology and physical science research.

U.S. West Coast and Alaska Marine Geohazards

Marine geohazards are sudden and extreme events beneath the ocean that threaten coastal populations. Such underwater hazards include earthquakes, volcanic eruptions, landslides, and tsunamis.

Devastating earthquakes in Japan (2011) and Chile (2010) that spawned pan-oceanic tsunamis sent a sobering reminder that U.S. coastlines are also vulnerable to natural disasters that originate in...

Woods Hole Coastal and Marine Science Center in the Field

In the Field; Land, Sea, and Air

Woods Hole Coastal and Marine Science Center scientists and staff study coastal and ocean resources and processes from the land, sea, and air, to shorelines and estuaries to the continental shelf, deep sea, lake floor, river bottoms and shallow subsurfaces environments.

 We have implemented new safety and fieldwork processes to...

Coastal and Estuarine Dynamics Project

Coastal and Estuarine Dynamics Project exists to support ocean, coastal and estuarine research. The staff have a broad set of skills; from instrument design and development to all forms of work at sea to software development and data management. The team has successfully deployed and recovered more than 1000 data collection platforms for research in the last 30 years.

Coastal Model Applications and Field Measurements

Numerical models are used by scientists, engineers, coastal managers, and the public to understand and predict processes in the coastal ocean. This project supports the development and application of open-source coastal models and has several objectives: 1) improve the code of numerical sediment-transport models by implementing new or improved algorithms; 2) obtain measurements of coastal...

Caribbean Tsunami and Earthquake Hazards Studies

Puerto Rico and the Virgin Islands are located at an active plate boundary between the North American plate and the northeast corner of the Caribbean plate. Plate movements have caused large magnitude earthquakes and devastating tsunamis. The USGS has an ongoing program to identify and map the faults in this region using various geophysical and geological methods in order to estimate the...
