The New Norris Hot Spring (Yellowstone Monthly Update - March 2026)

YVO Monthly Video Update March 2, 2026 KABOOM! That’s what Yellowstone is famous for – huge explosive volcanic eruptions. There’s really nothing brewing right now, the magma chamber is mostly solid, but there have been quite a few hydrothermal eruptions and small explosions in both Biscuit Basin and Norris Geyser Basin as water in the hydrothermal system flashes to steam. A curious new blue water pool formed in Norris Geyser Basin in late 2024 to early 2025 via a series of small explosions that threw out rock and excavated a small crater. This sort of activity is nothing new, as thermal features are commonly activating and going quiet across Yellowstone National Park. But it’s a great reminder about how dynamic the system is, and also how important it is to have monitoring instruments in place. During the month of February 2026, the University of Utah Seismograph Stations, which monitors and operates the Yellowstone seismic network, located 74 earthquakes. The largest was a Magnitude 2.4. Deformation measurements indicate a pause in uplift along the north caldera rim. Steamboat Geyser had one water eruption on February 27, and nearby Echinus Geyser (quiet since 2020) erupted about 40 times during the month. Yellowstone volcano remains at normal, background levels of activity. For questions, email [email protected] Read Caldera Chronicles: https://www.usgs.gov/volcanoes/yellow...
