Conference Objective

This conference is intended to bring together earth scientists who are working to resolve fundamental questions involving our understanding of earthquake energy budgets. That is, how is the physics of fault rupture related to the radiated seismic energy that is often associated with damaging ground motion? The conference will emphasize seismology, geology, laboratory rock mechanics, geophysics, geochemistry and the numerical modeling of earthquakes. A goal is to foster better communication amongst these groups of scientists to advance our understanding of how earthquakes work and the various energies involved in the seismic source processes.

Earth scientists representing many disciplines, who study various aspects of the earthquake energy budget, in the laboratory and in the field, will profit from the opportunity to meet as a group to learn first hand of new data, approaches, recent advances in understanding, and current challenges to improved understanding. Such interchange will promote the flow of information and understanding amongst the various disciplines and thereby encourage more effective, and collaborative, research activities in the future.
