Screenshot of Our Coast, Our Future (OCOF) interactive map view of Stinson Beach, California, showing extent of flooding predicted if subjected to a sea-level rise of 100 centimeters (about 40 inches) and elevated water levels caused by a 100-year storm.

Clear day view of Mauna Loa during tradewind conditions from the summit of Kīlauea Volcano.

A USGS electronics technician performs maintenance on a ShakeAlert Earthquake Early Warning (EEW) sensor station, located in the San Francisco Bay Area. ShakeAlert station components include strong-motion accelerometers, solar panel and battery power systems, and communications & telemetry equipment for communication with the wider ShakeAlert network. 

Mount Shasta, a steep-sided Cascade Range stratovolcano in Northern California, looms above Little Glass Mountain, a thick obsidian flow erupted from the Medicine Lake shield volcano about 1,000 years ago. These are just two of the young volcanic areas monitored by the USGS California Volcano Observatory. USGS photo.

Shaded-relief map of central California showing location of the Big Sur area (white dashed line). Red line shows the San Gregorio-Hosgri fault (SGHF) and the Big Sur Bend between Point Sur (PS) and Piedras Blancas (PB). Black lines show other faults.

Perspective view of part of the Big Sur Bend in the San Gregorio-Hosgri fault. The steep slope beside the fault results from uplift along the fault, which is part of the strike-slip fault system that forms the boundary in California between the Pacific and North American tectonic plates.

A WHCMSC and WHOI team recovered six intermediate period ocean bottom seismographs from the continental slope offshore New England in Georges Bank. The instruments had been deployed for about ten months to record background, ambient seismic noise.

These views of Mauna Loa are from near the Hawaiian Volcano Observatory looking toward the west. The view on left is typical during strong trade winds that blow the plume from Halema‘uma‘u Crater southwest of the summit area. The view on right is common during slack winds that allow vog conditions to develop in the summit area of Kīlauea.

Map showing the locations of all U.S. volcanoes with their threat category designated by color. Very high threat is red, high is orange, moderate is yellow, low is green, and very low is blue. 

The distribution of sediment textures within the study area. The bottom-type classification is from Barnhardt and others (1998) and is based on 16 sediment classes. The classification is based on four sediment units that include gravel (G), mud (M), rock (R), and sand (S). If the texture is greater than 90 percent, it is labeled with a single letter.

Most underwater seismic data is collected from large research vessels; however, the shoreface environment is shallower than areas in which most seismic surveys occur. To get the information we need to assess changes in shoreface geology, we mount our seismic instruments on pontoon floats and deploy the instrument from the beach.

We mount our seismic instrument on pontoon floats with wheels. This setup is deployed from the beach and eventually towed behind our survey vessel.
