As Chief of the Earthquake Hazards Team, Dr. Dieterich directed a group of about 200 researchers and support staff with an annual budget of $US 27M. In 2000, he received the American Geophysical Union, Bucher Medal in recognition of fundamental scientific contributions to understanding of the Earth's crust. Dr. Dieterich is a visiting scientist of QUAKES as part of the International Visitors Program of the APEC Cooperation for Earthquake Simulation sponsored by the US Geological Survey and Australian Research Council (ARC). He is
conducting collaborative research related to physical processes that occur in fault zones during earthquakes
and computer simulations of regional seismic activity.
