Map of horizontal velocities between July and December 2025 at Global Positioning System (GPS) stations P711 and NRWY (arrows and yellow circles; arrow length gives displacement rate) in the area between Norris Geyser Basin and Madison Junction. Dashed black line indicates boundary of Yellowstone Caldera and gray lines are roads.

Map of uplift as seen by interferometric synthetic aperture radar (InSAR) covering the time between October 7, 2024, and October 2, 2025 (the uplift began in July 2025) along the north rim of Yellowstone Caldera to the south of Norris Geyser Basin (NGB).

Plot of numbers of earthquakes per day in the immediate vicinity of the Norris Uplift Anomaly during 2024-2025. An increase in the rate of seismicity occurred in September-December 2025, especially in November. The largest earthquake during that time was M2.7.

Map view of relocated Yellowstone seismicity recorded during 2008-2022, colored by time, on the left. White line gives the outline of Yellowstone caldera. The A-A’ cross section through Yellowstone Lake is shown at the right and illustrates how seismic swarms that are distinct in time relate to one another. Adapted from Florez and others, 2025 (

Interferogram created from satellite radar data collected on October 7, 2024, and October 2, 2025, over the Yellowstone region by the Sentinel-1 satellite system. Colored fringes indicate a change in distance (called range change) between the satellite and ground surface that is caused by surface deformation during the time spanned.

Postfire runoff in the 2024 Elk Fire buran area near Dayton, Wyoming. Near the outlet of a burned watershed, postfire runoff deposited small boulders and mud, flattening the vegetation in this low-relief area.

Rocks, mud, and woody debris deposited by both flood and debris flow processes are visible in this upstream section of watershed burned by the 2024 Elk Fire near Dayton, Wyoming. The coarser material near the far channel edge was carried by a debris flow while the well-sorted finer material in the foreground has properties associated with flood flow.

Plot of temperatures measured by continuous loggers at Guardian Geyser (light red) and Valentine Geyser (dark red) on August 24, 2025. Activity at Guardian Geyser included episodic splashing for a few hours prior to the near-simultaneous eruptions of both geysers just after 6:30 a.m. MDT on this date. Data collected by Mara Reed, Yellowstone National Park.
