Seismometers record vibrations from a wide assortment of ground motion events. Each event type has a distinctive ground-motion signal with unique frequency and amplitude—its own seismic signature. Seismologists are trained to identify the source of seismic events seen on a webicorder based on its ‘seismic signature’.

USGS scientists, along with collaborators from the Marine Biological Laboratory, deployed a carbon flux tower on Great Marsh in 2017. Great Marsh is a 3800 acre salt marsh complex behind the Sandy Neck barrier beach in Barnstable, Cape Cod. This ecosystem is home to a variety of animals, including deer, fox, owls, and the rare Diamondback terrapin.

A new HVO webcam provides improved views of Mauna Loa's summit caldera, Moku‘āweoweo, from the northwest rim. This time-lapse sequence shows a full day on Sunday, Dec. 3, starting and ending at midnight. The full moon and sensitive low-light ability of the camera allow good views throughout the nighttime hours.

This video is of is a three-dimensional (3D) view of the Majuro Atoll, Republic of the Marshall Islands topobathymetric model which consists of topography (land elevation) and bathymetry (water depth). This video shows the importance of high-resolution, detailed topobathymetric models because the highest natural elevation for the Majuro Atoll is only three meters.

A routine helicopter overflight today provided good views of Mauna Loa's summit caldera. The video starts from the northeast end of the caldera, near North Pit, and travels southwest. In the southwest portion of the caldera, the prominent 1940 cone is followed by the 1949 cone on the caldera rim. The video ends with the steep walls of South Pit.
