In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route, California’s Highway 1, with rocks and dirt more than 65 feet deep. USGS monitors erosion along the landslide-prone cliffs of Big Sur, collecting aerial photos frequently throughout the year.

Video shot from drones yields details about changing landslide on California’s Big Sur coast

Josh Logan, a physical scientist at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California, operates an unmanned aerial system, or UAS, often called a "drone", that is equipped with a video camera.

USGS provides the data to Caltrans, the California Department of Transportation, whose heavy equipment and earth movers are shown here.

USGS research geophysicist Danny Brothers (right) and colleagues examine the surface of a sediment grab sample just pulled onto the deck of the Canadian Coast Guard Ship John P. Tully. The sample was collected from the top of a mud volcano north of the border between southeast Alaska and British Columbia.

Scientists prepare to lower a piston corer off Haida Gwaii, British Columbia, to sample seafloor sediment near the Queen Charlotte-Fairweather fault. Expedition scientists are studying layers of sediment in the cores they collected to identify and determine ages of past earthquakes along the fault.

Construction of the McKelvey Building, or Building 15, was completed in the mid-1990s on the USGS Western Region campus in Menlo Park, California. It houses many different USGS teams, such as Pacific Coastal and Marine Science Center, Water Science Center, and Volcano Science Center, and features many state-of-the-art laboratories.
