Ross will use QuakeCaster, a demonstration apparatus he developed, to explore the fundamental riddle of earthquakes : Why quakes are sporadic when the forces that drive them are steady. QuakeCaster also provides a way to visualize how researchers are makng progress in the difficult problem of earthquake forecasting. Using computer animations and slides to extend the demo into three dimensions, he will delve into the strange world of earthquake interaction and triggering. These illustrate how stress triggering can make sense out of earthquake sequences in California, Turkey, Japan, and Indonesia. Finally, Ross will argue that very rarely, megaquakes can trigger large aftershocks all over the globe.
