USGS–Hawaiian Volcano Observatory research geologist Matt Patrick talks about the lava lake in the Halema‘uma‘u Crater at the Kīlauea Volcano (Hawaii). Dr. Patrick describes the eruption that created the lava lake and points out features of the lake including moving crustal plates, gas bursts, spatter and collapse scars on the crater rim. Dr.

USGS–Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland, Deputy Scientist-in-Charge Wendy Stovall, and Chief Seismologist Jamie Farrell answer questions from the public about Yellowstone earthquakes, deformation, eruptive history, the magmatic plumbing system, and more, during a USGS Volcanoes Facebook Live event recorded on March 7, 2018, at the USGS–C

After a month, the wildfires of Southern California are nearly contained. Landsat 8 imagery shows the dramatic burn scars left behind.



At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.

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.

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’.

In March 2008, a new volcanic vent opened within Halema‘uma‘u, a crater at the summit of Kīlauea Volcano in Hawaiʻi Volcanoes National Park on the Island of Hawaiʻi. This new vent is one of two ongoing eruptions on the volcano. The other is on Kīlauea’s East Rift Zone, where vents have been erupting nearly nonstop since 1983.

The Thomas fire has burned more than 230,000 acres and continues to blaze across souther California. These images show some of the burn scar left behind.

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.

Before a hurricane, USGS Scientists undertake a data collection effort of a grand scale. They install a temporary mobile network of sensors along the coasts to collect additional data on the intensity of storm surge, one of the most dangerous elements of a hurricane.
