Geodynamics

Geodynamics (Geo: Earth and Dynamics: Forces) uses numerical models to quantitatively link our geophysical observations of the Earth's surface to the inaccessible processes at depth. The Numerical Modeling Team investigates natural hazards for a range of global targets.  

  • Megathrust earthquakes and Tsunami Genesis
  • Poroelastic deformation, viscoelastic creep, and triggered aftershocks 
  • Reservoir impoundment and induced seismicity
  • Fluid injection and fracture propagation
  • Magma flux and storage within active volcanoes
  • Heat flow and thermoelastic systems
  • Inverse models of InSAR and GPS data  
  • Optimization and uncertainty
  • Time series analyses, Gaussian Processes, and Kalman Filters 

Remote Sensing

  • Ground surface deformation measurement using InSAR
  • Photogrammetry (both land and drone-based acquisitions)
  • Hyperspectral/infrared spectroscopy

Seismology

  • Subduction zones dynamics
