Hydrothermal Monitoring Site in Norris Geyser Basin, Yellowstone National Park, Wyoming, United States of America

Description: 

Yellowstone National Park houses one of the largest and most active hydrothermal systems in the world containing over half of all known geysers. Additionally, the largest hydrothermal eruption crater is positioned in northern Yellowstone Lake (Mary Bay) approximately 35 kilometers to the southwest of Norris Geyser Basin. In addition, a small hydrothermal explosion occurred in the Norris Geyser Basin in 1989 when Porkchop Geyser exploded sending rocks and hot water/mud many meters from the feature. With such high seismic and hydrothermal risk, a network of monitoring sites is being developed to actively observe the signals produced by this vast plumbing system. During August of 2024, the University of Utah Seismograph Stations, U.S. Geological Survey, EarthScope Consortium, and Yellowstone National Park personnel installed a hydrothermal monitoring site (YNB) in the Norris Geyser Basin of Yellowstone National Park to complement the existing 3-component broadband site within the basin (YNM). Station YNB is composed of a 3-channel broadband seismic sensor (sampling at 100Hz), 3-channel infrasound array (sampling at 100Hz), compact weather station, and a full GNSS monument, and it is the most complete monitoring site in the Yellowstone region. In this study we will show seismic, infrasound, and geodetic signals that have been observed in the short time the station has been deployed and how data are being processed to assist in the further understanding of the Yellowstone Volcanic System.
