“…These studies show how seismic and geodetic measurements over a range of frequencies can be used to characterize the plumbing systems of, and pressures within, geysers. Additional imaging tools include using microphones (e.g., Namiki et al, ), forward looking infrared (e.g., Karlstrom et al, ), and ground‐penetrating radar to characterize the shallowest subsurface (e.g., Lynne et al, , ).…”

Broadband seismic data were recorded on the ground surface around an exceptionally regular eruptive system, geyser El Jefe, in the El Tatio geyser field, Chile. We identify two stages in the eruption, recharge and discharge, characterized by a radial expansion and contraction, respectively, of the surface around the geyser. We model the deformation with spherical sources that vary in size, location, and pressure, constrained by pressure observations inside the conduit that are highly correlated with deformation signals. We find that in order to fit the data, the subsurface pressure sources must be laterally offset from the geyser vent during the recharge phase and that they must migrate upward toward the vent during the eruption phase. This pattern is consistent with models in which ascending fluids accumulate and then are released from a bubble trap that is horizontally offset from the shallow conduit of the geyser.

“…GPR results show strong reflections in the upper 2–3.5 m, indicating layered sinter. Heterogeneous sinter layers result from variations in discharge flow rate and hydrothermal water temperatures over time (Lynne et al., 2017). The signal quickly attenuates beneath the strong reflectors, interpreted as the sinter‐till contact due to the high electrical conductivity values of the till.…”

Geophysical Imaging of the Shallow Geyser and Hydrothermal Reservoir Structures of Spouter Geyser, Yellowstone National Park: Geyser Dynamics I

Located in northwest Wyoming and extending into Montana and Idaho, Yellowstone National Park (YNP) is home to roughly five-hundred geysers, making it the most concentrated geyser field in the world (Bryan, 2018). Geysers are uncommon features, with less than 1,000 worldwide. Although geysers are rare and unique features, the knowledge of subsurface geyser structure and geyser eruption dynamics can be applied to other processes in YNP, including hydrothermal explosions (a significant geologic hazard within YNP) (R. L. Christiansen et al., 2007;Morton, 2021) and volcanic eruption dynamics (Hurwitz et al., 2021).
