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.

The Blackfoot Volcanic Field of southeast Idaho—a result of interaction between the Yellowstone hotspot and tectonic activity

The Blackfoot Volcanic Field in southeast Idaho is a unique product of Yellowstone hotspot volcanism. While it is chemically similar to other volcanic rocks in eastern Idaho that are related to the hotspot, it is located far from the hot spot track—a testament to its entanglement with tectonic activity of the Basin and Range Province.

How Big Was That Earthquake?

Earthquake magnitudes may seem straightforward, but a lot goes into their calculation, and multiple methods can be used.  These methods must account for many complications, like the impacts of local geology on the amplitude of shaking.  In Yellowstone, a modern seismic network and experienced analysts make it possible to determine the magnitudes of even the smallest earthquakes!
