Research Summary

Observational seismology focusing on analytic and numerical wave propagation modeling of broadband waveform and investigation of isotropic/anisotropic Earth structure relevant to plate tectonic processes and fast/slow earthquake behaviors near plate boundary. My continuing effort is to develop critical seismic observations and untangle tectonic/volcanic processes operating over different spatial and temporal scale.

Current efforts include: 

  • Volcano seismology: broadband seismic/geodetic observations vs. the interaction/feedback between volcanic conduit and magma chamber.
  • Seismic anisotropy in the core-mantle boundary region.
  • Hydration, compositional mixing/unmixing in the transition zone/uppermost lower mantle vs. long-term plate motion history.
  • Repeating/clustered earthquakes vs. Source scaling.
  • The nature of sub-slab and asthenosphere fabric; small-scale heterogeneity/anisotropy in the oceanic lithosphere.
  • Structural control of large/slow earthquakes in plate boundary.
  • Broadband seismic constraints of large earthquakes.
