USGS scientist BJ Reynolds sets up a solar-powered, satellite-uplinked GPS base station in the Fire Island Wilderness Area to support detailed elevation surveys.

Cliff erosion is a common storm-induced hazard along the West Coast. Two condemned apartment buildings along Esplanade Avenue in Pacifica, California are shown here before their demolition in 2016 and 2017.

Map showing the tracklines and grab sample sites of the 2014 and 2015 geophysical surveys offshore of the Delmarva Peninsula.

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Topsail, North Carolina. View looking northwest along the North Carolina shore. Elevated storm-induced water levels overtopped the low dunes here causing the dune to overwash. Sand was transported landward, burying the marsh (green arrow).

The effects of sea-level rise will vary by differences in the geomorphology and ecology of the landscape.  Images show marsh (top left) rocky coast (top right), barrier beach (bottom left), and coastal bluff (bottom right)

Enlarged details of Survey Area 1 showing new multibeam bathymetry data (rainbow colors) acquired on R/V Solstice near Cross Sound and Glacier Bay National Park, southeastern Alaska. Arrows highlight the surface expression, or trace, of the Queen Charlotte-Fairweather fault.

Profile of newly discovered volcano-like cone in sonar record collected off southern Alaska. The cone’s summit is at about 1,000 meters water depth. Note fluid plume (blue) rising more than 700 meters upward from the summit.

This USGS vessel acquires single-beam bathymetry in shallow nearshore environments. We acquire repeat bathymetry surveys over multiple years and compute changes in bathymetry, thus allowing us to identify hotspots of erosion and deposition on short timescales.

USGS scientists Paul Rydlund, Eric Looper and Jason Carron dock the boat and coordinate with emergency managers.

The sun angle was ideal this morning to show the complex texture on the surface of the lava lake in Halema‘uma‘u Crater at Kīlauea's summit. Spattering was active in the southeast portion of the lake. For scale, the lake is about 230 meters or 755 feet across.

USGS scientists Chris Rowden, Larry Buschmann and Bob Holmes were on the Mississippi River at St. Louis taking streamflow measurements on New Years Eve. This information is critical to the National Weather Service, the U.S. Army Corps of Engineers and emergency managers in making flood predictions and response.

USGS crews had two research vessels out measuring streamflow on the Mississippi River at St. Louis on New Years Eve. USGS scientists Eric Looper and Jason Carron are one of many USGS field crews out in the floodwaters over the holiday.

NBC Nightly News not only came out to interview USGS field crews on the Mississippi, they brought a team to fly overhead and capture video with a drone.

This map overlays a georeferenced thermal image mosaic onto a map of the flow field near Pu‘u ‘Ō‘ō; to show the distribution of active and recently active breakouts. The thermal images were collected during a helicopter overflight on December 30. The June 27th flow is outlined in green to highlight the previously mapped flow margin.
