Digital elevation model (DEM) of northern San Francisco Bay, California, created using bathymetry data collected between 1999 and 2016 (MLLW)

This image created using the Continuous Bathymetry and Elevation Models of the Massachusetts Coastal Zone and Continental Shelf, shows the entrance to the Buzzards Bay entrance to the Cape Cod Canal.

This image created using the Continuous Bathymetry and Elevation Models of the Massachusetts Coastal Zone and Continental Shelf, shows the three-dimensional perspective view of the Elizabeth Islands in the center of the image. Buzzards Bay is to the left (north) of the Elizabeth Islands, and Vineyard Sound is to the right (south).

This image created using the Continuous Bathymetry and Elevation Models of the Massachusetts Coastal Zone and Continental Shelf, shows the three-dimensional perspective view of Nantucket Island, MA looking from the Southeast to the Northwest.

After days of rain, a window of clear weather allowed HVO geologists to make observations and take measurements of the water pond at Kīlauea's summit on January 17, 2020. No major changes were observed, and the water level continues to slowly rise. 

This image created using the Continuous Bathymetry and Elevation Models of the Massachusetts Coastal Zone and Continental Shelf, shows Salem and Marblehead in the middle of the image and Rocky Neck in the upper middle.

After a sample was collected, HVO team members transferred water from the sampling device to plastic bottles. Team members took notes, measured water pH and evaluated water temperature data for each sample collected.

10 M5+ earthquakes recorded*
since Dec. 28, 2019 (including M6.4) large enough to do damage

This region of the California coastline is lined with coastal bluffs that have been shaped not only by runoff from rain, but also by wave- and wind-driven erosion. This photo from Pescadero State Beach displays an example of a bluff undergoing erosional processes. Water from the ocean, delivered in waves, can overtop some of these coastal bluffs.

The U.S. west coast is an area of complex coastal geography. This photograph depicts several examples of geological features along the California coastline that are shaped by varied coastal processes. The gently sloping beach, stark bluffs, and presence of smooth rocks suggests that the coastal processes shaping this coastline are complex.

Patrick Barnard explains how the Coastal Storm Modeling System (CoSMoS) integrates information from the Hazards Exposure Reporting and Analytics (HERA) mapper to understand the social and economic consequences of different flooding scenarios. 

USGS scientists were deployed to assess land deformation and movement after a large M6.4 earthquake struck Puerto Rico on January 7, 2020. The boardwalk in Ponce, Puerto Rico was damaged by the quake.

Houses were damaged during the M6.4 earthquake that struck Puerto Rico on January 7, 2020. Houses were tagged by local officials for whether they were safe or not.
