“…Hence, explaining the caldera subsidence in terms of a thermoelastic contraction model is unrealistic. Most likely mechanism can be inspired by the nearby fumarole activity, which suggests an intimate connection between ground displacement and hydrothermal system beneath the ground as suggested in other volcanos [e.g., Dzurisin et al, 1994;Lundgren et al, 2001;Lu et al, 2002;Mann and Freymueller, 2003]. Using a deflation source [Mogi, 1958] whose volume change rate is À5 Â 10 3 m 3 /yr at a depth of 500 m, we can explain the observed profile (B-B 0 ) as in Figure 4.…”

Stacked radar interferograms at Miyakejima volcano (Japan) between 1992 and 1998 showed two localized significantly deforming areas with a magnitude of 4∼6 mm/yr in the radar line of sight. One area is close to the 1983 eruption vent, and, using a simple closed analytical formulation, the deformation is interpreted as due to a thermoelastic contraction of a formerly intruded magma. The other one detected in the previous caldera is explained by a depressurization source, whose depth (500 m) coincides with that of a low resistivity zone interpreted as a hydrothermal reservoir. Also, our computed CO2 flux is consistent with in situ measurement data. The reservoir volume is significantly less than the collapsed volume in 2000, and its depth is much shallower than the void detected prior to the collapse. Hence, the depressurization would not directly induce the caldera collapse in 2000.

“…Those for August 1992to June 1993and June 1993to August 1995 show subsidence of the caldera floor by amounts that generally agree with leveling for similar time periods (all leveling surveys since 1984 were conducted in September). For the period 1992-1993, leveling measured -13B5 mm of subsidence near Le Hardy Rapids relative to Lake Butte (Dzurisin et al 1994), compared with approximately -20 mm indicated by the corresponding interferogram. For 1993-1995, leveling measured -39B5 mm compared with approximately -40 mm deduced from InSAR.…”

“…1; Smith 1979, 1982). Less extensive, annual surveys starting in 1983 showed additional uplift from 1976 to 1984 (22B1 mm/year) followed by progressive subsidence from 1985 to 1995 at an average rate of -19B1 mm/year (Dzurisin and Yamashita 1987;Dzurisin et al 1990Dzurisin et al , 1994. This paper compares leveling and satellite radar interferometry results for the period 1992-1998, including the most recent leveling survey in September 1998.…”

“…Such a mechanism has been invoked to explain inflation-deflation episodes in Yellowstone caldera, Wyoming [Dzurisin et al, 1994] and the formation of hydrothermal ore deposits and mineralized veins [Cathles and Smith, 1983]. Because of the large horizontal permeability of unaltered Hawaiian basalt flows [Souza and Voss, 1987], part of the ascending fluid plume is channeled laterally at shallow depths where rocks are as yet unaltered and relatively permeable.…”

Episodic thermal perturbations associated with groundwater flow: An example from Kilauea Volcano, Hawaii

[1] Temperature measurements in deep drill holes on volcano summits or upper flanks allow a quantitative analysis of groundwater induced heat transport within the edifice. We present a new temperature-depth profile from a deep well on the summit of Kilauea Volcano, Hawaii, and analyze it in conjunction with a temperature profile measured 26 years earlier. We propose two groundwater flow models to interpret the complex temperature profiles. The first is a modified confined lateral flow model (CLFM) with a continuous flux of hydrothermal fluid. In the second, transient flow model (TFM), slow conductive cooling follows a brief, advective heating event. We carry out numerical simulations to examine the timescales associated with each of the models. Results for both models are sensitive to the initial conditions, and with realistic initial conditions it takes between 750 and 1000 simulation years for either model to match the measured temperature profiles. With somewhat hotter initial conditions, results are consistent with onset of a hydrothermal plume $550 years ago, coincident with initiation of caldera subsidence. We show that the TFM is consistent with other data from hydrothermal systems and laboratory experiments and perhaps is more appropriate for this highly dynamic environment. The TFM implies that volcano-hydrothermal systems may be dominated by episodic events and that thermal perturbations may persist for several thousand years after hydrothermal flow has ceased.
