Dave Eaton's Research

My general research interests cover passive and global seismology, with an emphasis on teleseismic studies of continental lithosphere and Earth's deep interior. Other research interests include intraplate seismicity, regional tectonic studies, numerical simulation of seismic wave propagation, potential-field analysis, and microseismic studies applied to hydraulic fracturing, carbon capture and storage and mining.

The figure on the right shows rays that sample the outer core region, where uncertainty still exists with regard to composition. These SmKS waves are used to interrogate the velocity structure of the outermost core.

Some of my current projects include:

  • Detailed investigation of the continental lithosphere-asthenosphere boundary (LAB) using a synthetic seismogram approach.
  • Microseismic source analysis aimed at better characterizing rupture processes from fluid injection or rock freezing.
  • Teleseismic studies of lithospheric structure beneath Hudson Bay and Alberta.
