Many aspects of earthquake mechanics remain an enigma as we leave the twentieth century and enter the twenty-first. One potential bright spot is the realization that simple calculations of stress changes may explain some earthquake interactions, just as previous and ongoing studies of stress-changes have begun to explain human-induced seismicity. This chapter, which is an update of Harris [1998], reviews many published works and presents a compilation of quantitative earthquake-interaction studies from a stress-change perspective. This synthesis supplies some clues about certain aspects of earthquake mechanics. It also demonstrates that much work remains to be done before we have a complete story of how earthquakes work.
