Big Sur Landslides

On California’s Big Sur coast, the steep slopes at Mud Creek suffered a catastrophic collapse (May 20, 2017). On January 28, 2021, heavy rains from a two-day storm caused debris from fire-scarred slopes to wash out another section of road at Rat Creek. USGS scientists are monitoring this 100-mile section of the California coastline, in collaboration with the CA Department of Transportation....

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...
