From volcanologists to oceanographers, biologists to paleontologists, the U.S. Geological Survey employs thousands of scientists across the Earth sciences. Each has a unique role in supporting the bureau’s mission of providing “science that matters” to the American people.

An iceberg the size of Houston broke from the Brunt Ice Shelf Antarctica on January 22nd, 2023. Landsat images show the area one day before the break and several days after. A feature named Chasm One had been lengthening for years, and it finally reached all the way across the shelf.

Do animals prank humans? It sometimes feels that way, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland. Mike shows some of the ways animals have “interacted” with monitoring equipment in this April 1, 2023 monthly update of activity at Yellowstone Volcano.

Cheyenne Bottoms is the largest inland wetland in the United States. Water normally diverts from rivers into the vast marshland. The wetland water level changes with precipitation and surface flows. For example, 2007 was a wet year. And 2013 was a dry year.

Could an external event trigger a Yellowstone eruption? No, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland, that’s not how volcanoes work. Most of the pressure that drives a volcano toward eruption comes from within, from the exsolution of gases in the magmatic system.

Lava lake activity within Halema‘uma‘u crater, at the summit of Kīlauea, continues. On February 14, low fountaining was present at the central vent, which was supplying lava into a channel that flowed towards the large eastern lake.

The Sacramento and San Joaquin Rivers deliver half the amount of sediment they did 50 years ago to San Francisco Bay. Just as sea-level rise is accelerating, the demand for sediment is growing.

HVO’s B1cam shows one day of lava flow activity on the central eastern portion of Halema‘uma‘u crater’s floor on January 7, 2023
linkThis video, captured by the remote B1cam, shows lava erupting from multiple minor fountains (shown as a line of bright spots in the upper left of the video) and the cooling surface of the lava forming crustal plates that move toward the camera’s location.

HVO’s B1cam captures the opening moments of the afternoon eruption at Kīlauea Volcano on January 5, 2023
linkDuring the early morning hours of January 5, USGS Hawaiian Volcano Observatory scientists were closely monitoring an increase in earthquake activity and changes in the patterns of ground deformation at Kīlauea’s summit, indicating movement of magma in the subsurface.

Kīlauea volcano began erupting in Halema‘uma‘u crater around 4:34 pm HST on January 5, 2023, as captured in this KWcam video. Within hours, multiple dome fountains were active in the central-eastern portion of Halema‘uma‘u crater’s floor. There were several large bursts of lava from the newly opened vent.

This video, captured by the KWcam, shows a large burst of lava from the newly opened vent in Halema‘uma‘u crater, Kīlauea volcano at approximately 4:49 pm HST on January 5, 2023. This burst reached up to 50 meters (164 feet) high and sent a wave of lava across the crater floor.

High flows at streamgage 11172945 (Alameda Creek above Div Dam near Sunol, California) were captured by USGS hydrologic technician Louis Cannarozzi on 12/31/2022. Heavy precipitation caused higher-than-normal streamflow in many areas as an atmospheric river moved through northern California.
