Volcano and earthquake monitoring plan for the Yellowstone Caldera system, 2022–2032

First posted June 21, 2022 For additional information, contact: Director,Yellowstone Volcano ObservatoryU.S. Geological Survey 345 Middlefield Road, MS 910 Menlo Park, CA 94025 The Yellowstone Observatory (YVO) is a consortium of nine Federal, State, and academic agencies that: (1) provides timely monitoring hazards assessment volcanic, hydrothermal, earthquake activity in around National (2) conducts research to develop new approaches volcano better understand volcanic the region elsewhere. U.S. (USGS) arm YVO also responsible for reporting on Intermountain West United States.The previous plan spanned 2006–2015 focused strengthening region-wide coverage, or backbone, systems (Yellowstone Observatory, 2006). goals that have largely been achieved thanks significant investments instrumentation infrastructure, especially by Science Foundation EarthScope Plate Boundary (now known as Network Of Americas, NOTA) American Reinvestment Recovery Act. This revision plan, covering 2022–2032, builds upon these improvements while accounting insights into dynamics area’s seismic, hydrothermal activity. These are designed fill gaps network track associated with processes. include:Conversion remaining analog seismic stations digital,Addition Global Positioning System (GPS) vicinity Norris Geyser Basin other areas where changes deformation rate style observed,Implementation continuous gas several andImprovements lake, meteorological, hydrological activity, including occurring lake bottoms, aid understanding whether such might be influenced external forces, like environmental conditions.The 2022–2032 system proposes improve dynamic their hazards. To date, only single seismometer has placed within one Park’s geyser basins because noise boiling water can hinder interpretation overall magmatic but this concern mitigated backbone monitoring. Deployment geophysical, geochemical, hydrological, geological instruments will accompanied campaigns measure chemistry flux, well aerial satellite surveys thermal emissions.Close collaboration between member institutions needed achieve use derived data advance how Caldera similar work. At same time, attention must paid minimize impact efforts infrastructure environment. thus commits serving stewards natural, cultural, historical resources Park maximizing scientific gain betterment society.
