Project Abstract
 N/A
Intellectual Merit Earthquakes are preceded by a halo of earthquakes that decays with distance much like aftershocks. These foreshocks are an expected consequence of earthquake interaction and clustering. Their existence and location near the eventual rupture does not in itself indicate a preparatory strain accumulation process beyond ordinary earthquake triggering.
Broader Impacts The physical origins of foreshocks is one of the outstanding questions in earthquake prediction. Understanding precursory activity is an important component to ultimately understanding earthquake predictability.
