Modeling Turbulent Hydraulic Fracture Near a Free Surface
Tsai, Victor C.; Rice, James R. (American Society of Mechanical Engineers, 2012)Motivated by observations of subglacial drainage of water, we consider a hydraulic fracture problem in which the crack fluid flow. Using a hybrid Chebyshev/series-minimization numerical approach, we solve for the pressure ... -
New Perspectives in Crack and Fault Dynamics
Rice, James R. (Springer Netherlands, 2001)Recent observations on the dynamics of crack and fault rupture are described, together with related theory and simulations in the framework of continuum elastodynamics. Topics include configurational instabilities of tensile ... -
Nucleation of Slip-Weakening Rupture Instability in Landslides by Localized Increase of Pore Pressure
Viesca, Robert C.; Rice, James R. (American Geophysical Union, 2012)We model landslide initiation as slip surface growth driven by local elevated pore pressure, with particular reference to submarine slides. Assuming an elastic medium and friction that weakens with slip, solutions exist ... -
Off-fault Damage Patterns Due to Supershear Ruptures with Application to the 2001 Mw 8.1 Kokoxili (Kunlun) Tibet Earthquake
Bhat, Harsha S.; Dmowska, Renata; King, Goeffrey; Klinger, Yann; Rice, James R. (American Geophysical Union, 2007)We extend a model of a two-dimensional self-healing slip pulse, propagating dynamically in steady state with slip-weakening failure criterion, to the supershear regime in order to study the off-fault stressing induced by ... -
Off-fault Plasticity and Earthquake Rupture Dynamics: 1. Dry Materials or Neglect of Fluid Pressure Changes
Templeton, Elizabeth L.; Rice, James R. (American Geophysical Union, 2008)We analyze inelastic off-fault response during earthquakes. Spontaneous crack-like rupture, with slip weakening, is modeled in 2-D plane strain using an explicit dynamic finite element procedure. A Mohr-Coulomb type ... -
Off-Fault Plasticity and Earthquake Rupture Dynamics: 2. Effects of Fluid Saturation
Viesca, Robert C.; Templeton, Elizabeth L.; Rice, James R. (American Geophysical Union, 2008)We present an analysis of inelastic off-fault response in fluid-saturated material during earthquake shear rupture. The analysis is conducted for 2-D plane strain deformation using an explicit dynamic finite element ... -
Outburst Flooding Under Ice Sheets as Turbulently Driven Hydraulic Fracture
Rice, James R.; Tsai, Victor C. (American Society of Mechanical Engineers, 2010) -
Possible Mechanisms for Glacial Earthquakes
Tsai, Victor C.; Rice, James R.; Fahnestock, Mark (American Geophysical Union, 2008)The large glacial earthquakes reported on by Ekström et al. (2003, 2006) and Tsai and Ekström (2007) have previously been evaluated in terms of their seismic characteristics. In this paper we attempt to take constraints ... -
Role of Fault Branches in Earthquake Rupture Dynamics
Bhat, Harsha S.; Olives, Marion; Dmowska, Renata; Rice, James R. (American Geophysical Union, 2007)We analyze earthquake ruptures propagating along a straight “main” fault and encountering a finite-length branch fault. Such intersections are often observed in natural fault systems. The predicted effects of the interaction ... -
Rupture Nucleation on an Interface with a Power-Law relation between Stress and Displacement Discontinuity
Rice, James R.; Uenishi, Koji (Springer Verlag, 2010)We consider rupture initiation and instability on a displacement-weakening interface. It is assumed to follow a power-law relation between a component of displacement discontinuity (whether tensile opening in mode I or ... -
Seismicity Variations Associated with Aseismic Transients in Guerrero, Mexico, 1995-2006
Liu, Yajing; Rice, James R.; Larson, Kristine M. (Elsevier Science B.V., 2007)Primarily aseismic deformation transients in subduction zones, sometimes associated with tremors and low-frequency earthquakes, are a newly recognized mode of deformation. Stressing in the up-dip seismogenic zone is increased ... -
Slow Slip Predictions Based on Granit and Gabbro Friction Data Compared to GPS Measurements in Northern Cascadia
Yajing, Liu; Rice, James R. (American Geophysical Union, 2009)For episodic slow slip transients in subduction zones, a large uncertainty in comparing surface deformations predicted by forward modeling based on rate and state friction to GPS measurements lies in our limited knowledge ... -
Spontaneous and Triggered Aseismic Deformation Transients in a Subduction Fault Model
Liu, Yajing; Rice, James R. (American Geophysical Union, 2007)Aseismic deformation transients can emerge as a natural outcome of the rate and state friction processes revealed in laboratory fault-sliding experiments. When that constitutive formulation is applied to model subduction ... -
Stability and Localization of Rapid Shear in Fluid-Saturated Fault Gouge: 1. Linearized Stability Analysis
Rice, James Robert; Rudnicki, John W.; Platt, John Daniel (Wiley-Blackwell, 2014)Field observations of major earthquake fault zones show that shear deformation is often confined to principal slipping zones that may be of order 1–100 μm wide, located within a broader gouge layer of order 10–100 mm wide. ... -
Stability and Localization of Rapid Shear in Fluid-Saturated Fault Gouge: 2. Localized Zone Width and Strength Evolution
Platt, John Daniel; Rudnicki, John W.; Rice, James Robert (Wiley-Blackwell, 2014)Field and laboratory observations indicate that at seismic slip rates most shearing is confined to a very narrow zone, just a few tens to hundreds of microns wide, and sometimes as small as a few microns. Rice et al. (2014) ... -
Thermal Pressurization and Onset of Melting in Fault Zones
Rempel, Alan W.; Rice, James R. (American Geophysical Union, 2006)We examine how frictional heating drives the evolution of temperature, strength, and fracture energy during earthquake slip. For small slip distances, heat and pore fluid are unable to escape the shearing fault core, and ... -
Thermo- and Hydro-mechanical Processes along Faults during Rapid Slip
Rice, James R.; Dunham, Eric M.; Noda, Hiroyuki (CRC Press, 2009)Field observations of maturely slipped faults show a generally broad zone of damage by cracking and granulation. Nevertheless, large shear deformation, and therefore heat generation, in individual earthquakes takes place ... -
Tsunami Wave Analysis and Possibility of Splay Fault Rupture During the 2004 Indian Ocean Earthquake
DeDontney, Nora; Rice, James R. (Springer, 2012)The 2004 Indian Ocean tsunami was observed by two satellites, close in space and time, that traversed the Indian ocean two hours after the Sumatra-Andaman earthquake, but which observed different tsunami lead wave morphologies. ...
