Exploring the Subsurface

While Canada's west coast earthquakes often maintain the upper hand in sheer force, new research may help remove the quakes' other wildcard _ the element of surprise. To date, there have been few written records of earthquake activity for many faults that may still be active. So, those active faults must be identified by geological mapping or seismic surveys. In that sense, seismologist Andrew Calvert is literally venturing where few have gone before.

Calvert aims to acquire improved images of the Earth's subsurface using seismic reflection and refraction data. These methods can map structures at depths of 40 km or more with a resolution greater than other geophysical methods. He has used these seismic techniques to locate both shallow crustal faults and the Cascadia megathrust. Calvert employs WestGrid's computing power to support his seismogram modeling, seismogram simulations, as well as process the large volumes of imaging data he gathers.
