Landscape Response to Disturbance

This project characterizes and measures sediment-related effects of landscape disturbances (such as major storms, drought, or wildfire) and river management. We focus primarily on the U.S. west coast, and our work relates to natural hazards and resource management.

Samples Repository

Since 2002, the Woods Hole Coastal and Marine Science Center’s Samples Repository (WHCMSC) has been supporting research by providing secure storage for geological, biological, and geochemical samples; maintaining organization and an active inventory of these sample collections; as well as by providing access to these collections for study and reuse.

Landslides Triggered by the 2020 Puerto Rico Earthquake Sequence

A magnitude 6.4 earthquake occurred near Barrio Indios, Guayanilla, Puerto Rico on January 7, 2020. A study of the triggered landslides is ongoing.

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...

Seafloor Faults off Southern California

More than 22 million people live along Southern California’s coast, and many more migrate there every year. Faults and earthquake threats in this region have been heavily studied on land. USGS aims to boost our knowledge about faults on the seafloor, so they can be included in hazard assessments.

Remote Sensing Coastal Change

We use remote-sensing technologies—such as aerial photography, satellite imagery, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.

Underwater Landslides off Southern California

An earthquake can trigger a landslide along the ocean floor, which can then set off a tsunami. Without modern, high-resolution imaging of the seafloor, many historical slides and threats from future slides remain undetected.

Estuaries and large river deltas in the Pacific Northwest

Essential habitat for wild salmon and other wildlife borders river deltas and estuaries in the Pacific Northwest. These estuaries also support industry, agriculture, and a large human population that’s expected to double by the year 2060, but each could suffer from more severe river floods, higher sea level, and storm surges caused by climate change.

Coastal Climate Impacts

The impacts of climate change and sea-level rise around the Pacific and Arctic Oceans can vary tremendously. Thus far the vast majority of national and international impact assessments and models of coastal climate change have focused on low-relief coastlines that are not near seismically active zones. Furthermore, the degree to which extreme waves and wind will add further stress to coastal...
