“…Few investigators, however, have explored the relation between groundwater fluctuations due to earthquakes and geologic heterogeneity, or exploited the phenomenon for imaging 3‐D hydrologic property heterogeneity in a basin. A recent study by Lin et al [2004], using pore‐elastic and viscoelastic models and field data during the Chi‐Chi earthquakes in Taiwan during 1999, showed that the propagation of groundwater pressure waves induced by earthquakes is indeed influenced by geologic structures and hydrologic heterogeneity. They demonstrated that hydrologic properties of aquifers can be estimated using changes in groundwater levels before and after earthquakes.…”

[1] In this opinion paper we contend that high-resolution characterization, monitoring, and prediction are the key elements to advancing and reducing uncertainty in our understanding and prediction of subsurface processes at basin scales. First, we advocate that recently developed tomographic surveying is an effective and high-resolution approach for characterizing the field-scale subsurface. Fusion of different types of tomographic surveys further enhances the characterization. A basin is an appropriate scale for many water resources management purposes. We thereby propose the expansion of the tomographic surveying and data fusion concept to basin-scale characterization. In order to facilitate basin-scale tomographic surveys, different types of passive, basin-scale, CAT scan technologies are suggested that exploit recurrent natural stimuli (e.g., lightning, earthquakes, storm events, barometric variations, river-stage variations, etc.) as sources of excitations, along with implementation of sensor networks that provide long-term and spatially distributed monitoring of excitation as well as response signals on the land surface and in the subsurface. This vision for basin-scale subsurface characterization faces many significant technological challenges and requires interdisciplinary collaborations (e.g., surface and subsurface hydrology, geophysics, geology, geochemistry, information and sensor technology, applied mathematics, atmospheric science, etc.). We nevertheless contend that this should be a future direction for subsurface science research.

“…However, it is difficult or impractical to apply HT to basin-scale aquifer characterization because of ineffectiveness of artificial hydraulic tests for altering groundwater flow fields over kilometers or basin scales. Natural stimuli, such as atmospheric pressure variations [Rojstaczer, 1988], solid earth tides [Hsieh et al, 1988;Rojstaczer and Riley, 1990], ocean tides [Davis et al, 2000;Li et al, 2007b], precipitation [Jan et al, 2013], and even earthquake [Lin et al, 2004], are found to induce groundwater fluctuation from local to regional flow systems. For these reasons, Yeh et al [2008] proposed utilizing natural stimuli as excitation sources for basin-scale hydraulic tomographic surveys.…”

“…Acoustic wave phenomena in fluid‐containing porous media have received considerable attention in recent years, not only because of their practical importance in reservoir engineering [ Beresnev and Johnson , 1994; Kouznetsov et al , 1998; Seifert et al , 1998; Li et al , 2001] but also because of an increasing scientific awareness of poroelastic behavior in groundwater aquifers [ Schrefler and Zhan , 1991; Wang , 2000; Gambolati et al , 2000; Cosenza et al , 2002; Lin et al , 2004]. A macroscopic theory of wave propagation and attenuation in an isotropic porous medium bearing a single compressible viscous fluid can be formulated quantitatively using the Biot model [ Biot , 1956a, 1956b, 1962; Plona , 1980; Berryman , 1980; Johnson , 1986], wherein two interacting elastic continua are considered.…”

[1] Acoustic wave phenomena in porous media containing multiphase fluids have received considerable attention in recent years because of an increasing scientific awareness of poroelastic behavior in groundwater aquifers. To improve quantitative understanding of these phenomena, a general set of coupled partial differential equations was derived to describe dilatational wave propagation through an elastic porous medium permeated by two immiscible fluids. These equations, from which previous models of dilatational wave propagation can be recovered as special cases, incorporate both inertial coupling and viscous drag in an Eulerian frame of reference. Two important poroelasticity concepts, the linearized increment of fluid content and the closure relation for porosity change, originally defined for an elastic porous medium containing a single fluid, also are generalized for a two-fluid system. To examine the impact of relative fluid saturation and wave excitation frequency (50, 100, 150, and 200 Hz) on free dilatational wave behavior in unconsolidated porous media, numerical simulations of the three possible modes of wave motion were conducted for Columbia fine sandy loam containing either an air-water or oil-water mixture. The results showed that the propagating (P1) mode, which results from in-phase motions of the solid framework and the two pore fluids, moves with a speed equal to the square root of the ratio of an effective bulk modulus to an effective density of the fluid-containing porous medium, regardless of fluid saturation and for both fluid mixtures. The nature of the pore fluids exerts a significant influence on the attenuation of the P1 wave. In the air-water system, attenuation was controlled by material density differences and the relative mobilities of the pore fluids, whereas in the oil-water system an effective kinematic shear viscosity of the pore fluids was the controlling parameter. On the other hand, the speed and attenuation of the two diffusive modes (P2, resulting from out-of-phase motions of the solid framework and the fluids, and P3, the result of capillary pressure fluctuations) were closely associated with an effective dynamic shear viscosity of the pore fluids. The P2 and P3 waves also had the same constant value of the quality factor, and by comparison of our results with previous research on these two dilatational wave modes in sandstones, both were found to be sensitive to the state of consolidation of the porous medium.
