Offshore Faults along Central and Northern California

From Point Conception to Cape Mendocino, seafloor faults have been, in the past, mapped in varying ways and without enough detail to assess their earthquake potential. To provide this important information, USGS uses advanced technology to image offshore faults that could trigger devastating earthquakes near densely populated areas and a nuclear power plant.

A Shallow to Deep View Inside the Hydrothermally Altered and Mineralized Silverton Caldera Complex: New Geologic Insights Gained From Modern Geophysical Interpretations

The Silverton caldera complex in southwest Colorado hosts base and precious metals that have been mined since the late 1800s. Extensive mine workings, excellent bedrock exposures, and deeply incised drainages make this area a natural laboratory ideally suited for furthering our understanding of the mineral systems in a volcanic environment. In addition, state-of-the-art geophysical...

LCMAP Change Stories: Gone in 60 Seconds

At first glance, the most striking patterns in land cover change over time in this animation of the Oso, Washington area would appear to be forest harvest and regrowth, but a more dramatic change emerged in 2014.

Coastal Sediment Availability and Flux (CSAF)

Sediments are the foundation of coastal systems, including barrier islands. Their behavior is driven by not only sediment availability, but also sediment exchanges between barrier island environments. We collect geophysical, remote sensing, and sediment data to estimate these parameters, which are integrated with models to improve prediction of coastal response to extreme storms and sea-level...

Coastal Change at Fire Island, a geonarrative

Approximately 60 miles from the skyscrapers and fast-pace of New York City, Fire Island stretches 31 miles along the south shore of Long Island. The sandy beaches and pristine wilderness areas of Fire Island National Seashore are dotted with secluded residential communities. The island is fronted by the Atlantic Ocean, so in addition to its natural and recreational value, Fire Island is also...

Using Unmanned Aerial Systems (UAS) Capabilities to Help Identify Giant Salvinia (Salvinia molesta) and the effects of Salvinia weevil (Cyrtogagous salviniae)

USGS is collecting remotely sensed data to classify Salvinia molesta, a non-native aquatic species that reduces light and oxygen levels in water, making it unsuitable for fish and other aquatic plant life.
