This close-up view of the active western portion of the Halema‘uma‘u lava lake at the summit of Kīlauea was captured on Thursday, May 6 through the lens of a laser rangefinder used by HVO scientists to measure distances to features within the crater.

Scientific divers BJ Reynolds and Hunter Wilcox prepare to lower an Acoustic Doppler Current Profiler (ADCP) into the water. The ADCP now sits on the bottom of the ocean off Madeira beach, Florida in 5m water depth.

View of the active surface lava in the western portion of Halema‘uma‘u, at the summit of Kīlauea Volcano. The west vent (upper left) continues to erupt lava into the lava lake through an inlet near the base of the cone.

Lava continues to flow from the western vent (bottom left) into the lava lake at Halema‘uma‘u Crater at the summit of Kīlauea Volcano, Island of Hawai‘i. A portion of the active surface of the lava lake can be seen here with orange, incandescent lava between the west vent and the main island. This photograph was taken on Wednesday, March 5, 2021, at 12:37 p.m.

The image shown displays a portion of the lidar data collected by the USGS for the SAFSOC Project. Our goal is to study and map surficial processes and landforms related to tectonism, specifically the San Andreas Fault system.

Scientists from the U.S. Geological Survey conducted a dye-trace assessment on May 5, 2021 along the Missouri River near Huntsdale, Missouri. The assessment helped scientists understand how larvae from the critically endangered pallid sturgeon drift downstream after hatching and how they find supportive habitat in the complex Missouri River.

Teams at the USGS EROS Center have completed fire atlases for nine National Parks across the U.S. Each atlas defines the size and severity of each fire in each park since 1984, including fires too small to be mapped by other programs. Yellowstone National Park has had nearly 100 fires, for example, ranging from a few acres to thousands of acres.

This tree-ring sample from an avalanche path captures 256 years of data between the years 1777 and 2013. The scars in 1818 and 1974 are examples of mechanical damage caused by an avalanche. The pith is the center of the tree.

Within the busy boroughs of Brooklyn and Queens, New York City, is Jamaica Bay—a complex urban ecosystem almost the size of Manhattan that consists of salt marsh islands, various waterways, meadowlands and two freshwater ponds.

GPS campaign survey stations high on the flanks of Mauna Loa offer expansive views of neighboring volcanoes. From this station located west of Mauna Loa summit, Hualālai volcano is visible. Most Mauna Loa GPS campaign survey sites have been occupied every year since 1996, whereas less active volcanoes Hualālai and Haleakalā are surveyed every 3–5 years.
