Project Abstract
 Observations of earthquake triggering, especially the transition from foreshock to main shock to aftershock, provide a useful tool to test various models of earthquake interaction, and to constrain the physics of earthquake rupture nucleation, propagation, and arrest. Taking advantage of recent dramatic improvements in earthquake relocation accuracy allowed by waveform cross-correlation [e.g., Shearer et al., 2005], we propose to systematically examine the underlying driving forces for the space-time evolutions of seismicity around numerous small main shock ruptures in California and Japan.
