Bio

Population growth is increasingly bringing more people into areas prone to natural hazards, especially earthquakes, tsunamis, and volcanic eruptions—as the events of the past few years have demonstrated. Motivated by both the desire to reduce risk and an innate curiosity about how the natural world operates, my personal research focuses on the development and use of physics-based computational simulations to characterize and understand earthquakes, tsunamis, and volcanoes, and similar phenomena. With a background in theoretical physics and mathematics, my approach is to identify the fundamental mechanical processes governing the system, develop numerical models incorporating these processes, validate them using geophysical observations, and then use the models to predict system behavior. Specific research areas include earthquake rupture dynamics, tsunami generation, volcano seismology and infrasound, ice stream stick-slip events and flexural-gravity waves in ice shelves, and numerical methods for wave propagation

Current Research and Scholarly Interests

Research
I study the mechanics and physics of earthquakes, volcanoes, and tsunamis. Our group has been developing numerical models of earthquake rupture propagation that incorporate sophisticated descriptions of the processes within and around the fault zone that are thought to control how fault strength evolves during rapid slip. The models include transport of heat and pore fluid within fault zones, microscopic weakening processes that have been observed in laboratory experiments, and inelastic deformation of the off-fault material. We are using these models to explore how earthquake ruptures excite seismic waves, with a particular focus on strong ground motion and seismic hazard. Recently, my group and I have been working to understand the origin of incoherent high frequency ground motion by directly modeling rupture propagation on fractally rough fault surfaces. We are also studying subduction zone megathrust earthquakes, like the March 2011 Tohoku-Oki event that was responsible for the devastating tsunami in Japan. In addition to the rupture process, we are studying the excitation of ocean acoustic waves and tsunamis in these events. These modeling efforts involve high-performance computing, using resources at the Stanford Center for Computational Earth and Environmental Science and elsewhere. In addition to earthquakes, we study seismic waves from volcanic eruptions. We have developed a code that solves for the fully coupled flow of a compressible, viscous magma through cracks and conduits in deformable solids. We hope to learn about the dynamics of eruptions from seismic signals recorded at Earth's surface.

Teaching
As part of the geophysics undergraduate curriculum I teach a course (Geophysics 120: Ice, Water, Fire) in which we apply the principles of continuum mechanics to explain readily observed properties of tsunamis and ocean waves, volcanic eruptions, and ice sheets and glaciers. At the graduate level, I teach earthquake seismology (Geophysics 287: Earthquake Seismology) and have lead seminars on several topics including strong ground motion modeling for seismic hazard analysis, fluid dynamics of volcanic eruptions, and earthquake rupture dynamics. I am also an affiliated faculty member of Stanford's Institute for Computational and Mathematical Engineering (ICME) program. As part of that program, I teach an undergraduate scientific computing course (CME 108: Introduction to Scientific Computing).

    Abstract

    Fault-zone fluids control effective normal stress and fault strength. While most earthquake models assume a fixed pore fluid pressure distribution, geologists have documented fault valving behavior, that is, cyclic changes in pressure and unsteady fluid migration along faults. Here we quantify fault valving through 2-D antiplane shear simulations of earthquake sequences on a strike-slip fault with rate-and-state friction, upward Darcy flow along a permeable fault zone, and permeability evolution. Fluid overpressure develops during the interseismic period, when healing/sealing reduces fault permeability, and is released after earthquakes enhance permeability. Coupling between fluid flow, permeability and pressure evolution, and slip produces fluid-driven aseismic slip near the base of the seismogenic zone and earthquake swarms within the seismogenic zone, as ascending fluids pressurize and weaken the fault. This model might explain observations of late interseismic fault unlocking, slow slip and creep transients, swarm seismicity, and rapid pressure/stress transmission in induced seismicity sequences.

  • Strong Ground Motion Prediction Using Virtual Earthquakes SCIENCE Denolle, M. A., Dunham, E. M., Prieto, G. A., Beroza, G. C. 2014; 343 (6169): 399-403

    Abstract

    Sedimentary basins increase the damaging effects of earthquakes by trapping and amplifying seismic waves. Simulations of seismic wave propagation in sedimentary basins capture this effect; however, there exists no method to validate these results for earthquakes that have not yet occurred. We present a new approach for ground motion prediction that uses the ambient seismic field. We apply our method to a suite of magnitude 7 scenario earthquakes on the southern San Andreas fault and compare our ground motion predictions with simulations. Both methods find strong amplification and coupling of source and structure effects, but they predict substantially different shaking patterns across the Los Angeles Basin. The virtual earthquake approach provides a new approach for predicting long-period strong ground motion.

  • A supershear transition mechanism for cracks SCIENCE Dunham, E. M., Favreau, P., Carlson, J. M. 2003; 299 (5612): 1557-1559

    Abstract

    Seismic data indicate that fault ruptures follow complicated paths with variable velocity because of inhomogeneities in initial stress or fracture energy. We report a phenomenon unique to three-dimensional cracks: Locally stronger fault sections, rather than slowing ruptures, drive them forward at velocities exceeding the shear wave speed. This supershear mechanism differentiates barrier and asperity models of fault heterogeneity, which previously have been regarded as indistinguishable. High strength barriers concentrate energy, producing potentially destructive pulses of strong ground motion.
