Current research and/or projects

Dr. Herb Dragert obtained an honours  B.Sc. degree in Mathematics & Physics at the University of Toronto in 1968, and his M.Sc. and Ph.D. degrees in Geophysics at the University of British Columbia in 1970 and 1973 respectively. He next held a NATO Post doctoral Fellowship at the Institute for Geophysics, Goettingen, Germany, and returned to Canada to teach at UBC in the fall of 1974. He joined the Gravity and Geodynamics Division of the Earth Physics Branch in Ottawa in the summer of 1976, and moved to PGC at the end of 1978. He currently heads the ESS Crustal Deformation Service which was established in 2003 and also holds an adjunct professor position with the School  of Earth and Ocean Sciences at the University of Victoria. He was  appointed to the Board of Directors of UNAVCO (University Navstar  Consortium) in June 2003. Over the past 28 years, his principal area of research has been the study of crustal deformation within active seismic areas on the west coast of Canada using geodetic techniques such as leveling, precise gravity, laser ranging trilateration, and GPS. Beginning in 1992, under his direction, the Geological Survey of Canada established the Western Canada Deformation Array, the first continuous GPS network in Canada for the express purpose of monitoring crustal motions. It was data from this network that provided the key information which led to the discovery of "Episodic Tremor and Slip" in the Cascadia Subduction Zone. Dr. Dragert has also led Canadian involvement in the US EarthScope program which has resulted in a cooperative effort for more intensive crustal deformation monitoring along the Cascadia Subduction Zone, including the first installation of borehole strainmeters in Canada.
