The Yellowstone Plateau hosts an active volcanic system, with subterranean magma (molten rock), boiling, pressurized waters, and a variety of active faults with significant earthquake hazard. Within the next few decades, large and moderate earthquakes and hydrothermal explosions are certain to occur. Volcanic eruptions are less likely, but are ultimately inevitable in this active volcanic region. This document summarizes protocols and tools to be used by the Yellowstone Volcano Observatory (YVO) during earthquakes, volcanic eruptions, hydrothermal explosions or any similar geological activity that could lead to a volcanic eruption. As needed, YVO will be an advisor within the National Incident Management System (NIMS). The YVO Branch within the Operations Section of the Incident Command will consist of three prescribed groups (Monitoring, Information, and Support). The three groups and their subsidiary teams form a scalable system to respond to a variety of scenarios of geological and volcanic unrest. | Protocols For Geologic Hazards Response By The Yellowstone Volcano Observatory by United U S Department of the Interior, Paperback | Indigo Chapters
