  • Interests

  • Life of Earthquakes
  • Understanding earthquake source processes is critically important for saving lives and avoiding economic losses. Questions include: How does an earthquake initiate and develop? What make the final size of earthquakes large or small? What make the pattern of earthquakes simple or complex?

  • Dynamics in the Earth
  • Dynamics inside the Earth define the movement of Earth's tectonic plates, which accounts for the most powerful seismic events on the planet. Questions include: How do the interactions of faults modulate the dynamics of earthquakes? How to constrain the shape and stress state of the inaccessibly deep subduction slab? How do we learn about the dynamical evolution over the long history of the subduction slabs relying only on present-day observations?

  • Natural Hazards
  • Assessing and alerting natural hazards, such as earthquakes and tsunamis, are vital yet difficult due to the unpredictable nature, short reaction time, and diverse impact levels and site conditions. Questions include: Can we combine multi-geophysical observations and modelings for rapid and accurate responses to earthquakes and tsunamis? Can we accurately assess the different levels of seismic hazard for different regions?

  • Sustainable Resilience
  • Geothermal energy is a promising type of renewable energy. How to utilize the understanding of fluid-fault interactions to guide the enhanced geothermal system production? How to minimize the negative consequence of induced earthquakes during the geothermal exploration and carbon sequestration with the understanding of rupture processes? How to incorporate the seismic and geodetic observations to find the easily-accessible and safe geothermal resources?
