The Yellowstone Volcano Observatory (YVO) is a consortium of nine state and federal agencies who provide timely monitoring and hazard assessment of volcanic, hydrothermal, and earthquake activity in the Yellowstone Plateau region. The USGS arm of YVO is also responsible for monitoring and reporting on volcanic activity in the intermountain west U.S. states.

Seeing is believing: Livestream video monitoring of Hawaiian eruptions Seeing is believing: Livestream video monitoring of Hawaiian eruptions

Livestream video has become a crucial tool for volcano monitoring in recent years, building upon the use of webcam snapshots that have been common for the past two decades. In Hawaii, livestream video was first tested in 2018, and today, livestream video is a vital tool for the Hawaiian Volcano Observatory and partner agencies (National Park Service and Hawaiʻi County Civil Defense) as...

The first instrumentally detected hydrothermal explosion in Yellowstone National Park The first instrumentally detected hydrothermal explosion in Yellowstone National Park

Hydrothermal explosions are one of the geological hazards most likely to impact people in Yellowstone National Park, but their frequency is poorly known. Infrasound and seismic sensors identified an explosion in Norris Geyser Basin on 15 April 2024, at 14:56 MDT (20:56 UTC)—the first instrumentally detected hydrothermal explosion in the Yellowstone region. The event affected an area tens...

Magmatic volatiles in the Yellowstone Plateau volcanic field: The knowns, the unknowns, and the uncertainties Magmatic volatiles in the Yellowstone Plateau volcanic field: The knowns, the unknowns, and the uncertainties

The Yellowstone Plateau volcanic field has a large magmatic system supplying heat and mass into the overlying hydrothermal system. To interpret changes in the composition and/or emission rates of hydrothermal fluids as possible indicators of volcanic unrest requires discriminating between magmatic, crustal, hydrothermal, and hybrid sources and processes. Significant progress in...
