Abstract:Foreshocks, though well‐documented phenomena preceding many large earthquakes, have limited forecasting utility due to their non‐pervasive occurrence and non‐distinctive characteristics. Using California as an example, we investigate how seismic monitoring capability, particularly the completeness magnitude (), influences the inferred proportion of mainshocks with foreshocks (). We test four foreshock identification methods, namely the fixed‐window, nearest neighbor clustering, empirical statistical (ES) methods and the epidemic‐type aftershock sequence (ETAS) model. The fixed‐window method sh
