A U.S. Geological Survey streamgage near Hunstville, Utah is celebrating 100 years of monitoring streamflow on the south fork of the Ogden River. The streamgage has been monitoring water levels and flow since March 21, 1921, making it one of 25 centennial gauges in Utah.

This thermal video shows the lava lake in Halema‘uma‘u, at the summit of Kīlauea. Lava is supplied from the western fissure, in the upper left portion of the video. Small vent openings atop the western fissure exhibit rhythmic gas puffing. The video is shown at 5x speed.

Metals and minerals are vital components of medical devices that allow millions of people to enjoy healthy lifestyles. Devices implanted into the human body can replace, support, or enhance an existing body part. Other devices can diagnose, monitor, or treat clinical conditions, both saving lives and improving people’s quality of life.

Winter temperature extremes control the distributions of subtropical fishes. Common snook (Centropomus undecimalis), aggregate at a spring in northern Florida during winter. Snook are warm saltwater game fish, common in Florida, that have been moving further northward as extreme cold spells become less frequent and less intense.

View of the lava lake from the south rim of Halema‘uma‘u, at the summit of Kīlauea, looking north. The western (left) portion of the lava lake remains active, with small scale crustal foundering events. Lava enters the lake at two sources approximately 20 to 30 meters (65 to 100 ft) apart at the base of the western vent spatter cone.

This map of Halema‘uma‘u at the summit of Kīlauea shows 20 m (66 ft) contour lines (dark gray) that mark locations of equal elevation above sea level (asl). The map shows that the lava lake has filled 221 m (725 ft) of the crater, to an elevation of 737 m (2418 ft) asl since the eruption began on December 20, 2020.

View of the lava lake from the southern rim of Halema‘uma‘u, at the summit of Kīlauea, looking north. The western portion of the lava lake remains active, with small scale crustal foundering events. The white steam from the crater walls is more pronounced due to the heavy rain of the last couple of days.

This map shows the response time people can expect based on Mauna Loa eruptions over the past 200 years. Different sectors around Mauna Loa are colored according to how quickly lava flows can reach populated areas. The warmer the color, the more quickly the flows travel.
