  • Dr Freed Rheological Studies
    Setting up a GPS receiver in a tent city in Haiti following the 2010 earthquake to monitor postseismic deformation.
  • 2 Earthquake Triggering
    Finite element model calculated stress changes following the 1992 Landers earthquake, which may explain the triggering of the subsequent Hector Mine quake.
  • 2 Planetary Science
    Finite element model calculation of the cooling of asteroid 433 Eros due to orbital transfer.

The Geodynamics Modeling Group @ Purdue

Our group develops numerical models to quantify fundamental processes in four areas of geodynamics: rheology, earthquake triggering, plate tectonics, and planetary science. Our primary tool is the development of viscoelastic finite element models that enable us use geodetic and seismological observations of faulting and surface deformation to test hypotheses associated with the development of fault systems and rheologic structure and to calculate the evolution of crustal stresses through time in various tectonic settings. Often our target is associated with identifying earthquake hazards by determining which faults in a region have accumulated the most unrelieved stress or are currently experiences the highest loading rates.
