Imaging the Deep Subsurface Plumbing of Old Faithful Geyser From Low‐Frequency Hydrothermal Tremor Migration

The plumbing of Old Faithful Geyser revealed by hydrothermal tremor

Old Faithful Geyser in Yellowstone National Park (USA) has attracted numerous scientific investigations for over two centuries in order to better understand its geological structure, the physics of its eruptions, and the controls of its intermittency. Using data acquired with a seismic array in 1992, we track the sources of hydrothermal tremor produced by boiling and cavitation inside the geyse...

Mechanics of Old Faithful Geyser, Calistoga, California

[1] In order to probe the subsurface dynamics associated with geyser eruptions, we measured ground deformation at Old Faithful Geyser of Calistoga, CA. We present a physical model in which recharge during the period preceding an eruption is driven by pressure differences relative to the aquifer supplying the geyser. The model predicts that pressure and ground deformation are characterized by an...

Plumbing the depths – testing natural tracers of subsurface CO2 origin and migration, Utah, USA

The effective geological storage of liquid CO2 in porous subsurface rock will require the ability to track, and identify the origin of, any CO2 seepage measured at the near-surface. In a study relevant to postemplacement seepage, we examine natural CO2 springs around Green River, on the Colorado Plateau USA, in an attempt to determine the CO2 origins. We use a combination of natural geochemical...

Seismicity at Old Faithful Geyser: an Isolated Source of Geothermal Noise and Possible Analogue of Volcanic Seismicity

Kieffer, S.W., 1984. Seismicity at Old Faithful Geyser: an isolated source of geothermal noise and possible analogue of volcanic seismicity.A., is a relatively isolated source of seismic noise and exhibits seismic behavior similar to that observed at many volcanoes, including "bubblequakes" that resemble B-type "earthquakes", harmonic tremor before and during eruptions, and periods of seismic q...
