Plot of size versus annual probability for hydrothermal explosion craters in Yellowstone National Park. The line is a model based on the energy required to form a crater of a specific size, and it is fit to known hydrothermal explosion craters in Yellowstone National Park.

Graph showing explosions recorded at Black Diamond Pool in Biscuit Basin, Yellowstone National Park, during 2006 through 2016. Confirmed events refer to eruptions that were witnessed, recorded by temperature loggers, or inferred from their aftermath. Unconfirmed events refer to eruptions that were questionable or might have been misattributed to Black Diamond.

(A) Photomicrograph of a quartz-hosted embayment from the Mesa Falls Tuff. “MI” indicates a glassy inclusion of melt within the crystal. (B) Thickness (in centimeters) and extent of the Mesa Falls ash flow deposit (pink areas) and its source, Henrys Fork Caldera (dashed line). Figure by Kenneth Befus, University of Texas at Austin.

(A) Water distribution in a quartz-hosted embayment measured with synchrotron Fourier Transform Infrared spectroscopy. Warmer colors indicate higher concentrations of water. Dashed line shows a transect of water content that is modeled in panel (B) to indicate that the emplacement temperature of the ash flow deposit must have been about 500 °C (930 °F).

Shaded relief location map for the East Gallatin-Reese Creek fault system (EGRCFS) in northwest Yellowstone National Park (YNP). The location of the EGRCFS is shown as mapped in the U.S.

Lidar hillshade maps of fault scarps that offset Pinedale glacial till along the East Gallatin-Reese Creek fault system (EGRCFS) near Fawn Creek (A) and Panther Creek (B). Fault scarps are visible as darker lineaments in the hillshade and are marked by the black arrows. Red rectangles on inset maps show location along the EGRCFS.

What just happened at Biscuit Basin in Yellowstone National Park? Kaboom! Visitors witnessed a towering plume of steam, rock and mud rise several hundred feet into the air. The brief July 23 event was a classic example of a hydrothermal explosion, not a volcanic eruption.

The beautiful Morning Glory pool is located near Old Faithful. However, it has changed over time because of people and past climate. But how?

Up until the 1950s, visitors to the Old Faithful area could take a dip. Not at a geyser, but in a real swimming pool. The full story is in this month’s video update.

Mount St. Helens and Yellowstone are two of the most well-known volcanoes in the United States. They have some pretty obvious differences, but they have some similarities as well. So, just how similar are Mount St. Helens and Yellowstone?

Need time to concentrate or relax? Then listen to the gurgling and bubbly sounds of Steamboat Geyser in Yellowstone National Park, Wyoming. "Steamboat Geyser is the world’s tallest active geyser. It showers watchers and drenches the walkway. Days, months, or years pass between the major eruptions of Steamboat Geyser.

Yellowstone National Park has experienced several hundred small earthquakes in the past few weeks. So what's going on?
Dr. Jake Lowenstern, USGS Scientist-In-Charge at the Yellowstone Volcano Observatory, tells us what's happening and how scientists monitor volcano and earthquake activity at Yellowstone.

The camera view is south-southeast over Yellowstone Lake from the cell phone tower near Fishing Bridge. Stevenson Island is visible within the lake on the right. The view extends down the Southeast Arm between the Promontory (low ridge rising from the lake) and the eastern shore.
