Halema‘uma‘u eruptive activity on 05 May 2021
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.

Hillshade of lidar acquired within the Pinto Mountain Fault Zone
Hillshade of lidar acquired within the Pinto Mountain Fault ZoneThe 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.

USGS Missouri River Dye Tracing Assessment
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.

Eyes on Earth Episode 49 – Fire Atlas
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.

Tree-ring sample from an avalanche path
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.

Jamaica Bay UVVR
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.

Annual Mauna Loa GPS Survey—2021
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.

Everglades National Park UVVR
Everglades National Park in South Florida is the largest subtropical wetland ecosystem in North America, consisting of about 1.5 million acres of mangrove forests and other coastal wetlands. Mangroves are salt-tolerant trees that thrive amidst the harsh growing conditions of the coast.
