Yellowstone Volcano Observatory

Home

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.

How and why do we collect sediment cores in Yellowstone Lake?

In August 2021, YVO scientists collected sediment cores from the floor of Yellowstone Lake. Analysis of the sediment composition, as well as the fluids contained within the sediment, can provide new information about hydrothermal activity occurring out of view beneath the lake water.

Taking Yellowstone seismology to the classroom for some “deep learning”

Locating earthquakes in Yellowstone is a time-intensive process that requires the trained eye and extensive experience of a human analyst. But advances in computer algorithms, known as “machine learning” tools, hold promise for automatically locating earthquakes that might otherwise be overlooked, and the dawn of a new age in seismology!

Scientists can now “sniff” Yellowstone gases in real time

Much is known about how the chemical compositions of gases vary across the Yellowstone volcanic system, but how they vary in time has remained largely a mystery.  Our understanding should greatly improve with a recent installation of a station that continuously monitors gases and communicates those data in real time.
