Fig. 17From: Statistical study on the regional characteristics of seismic activity in and around Japan: frequency-magnitude distribution and tidal correlationSame as Fig. 15, but for \(D\). The dashed black lines are the PDDs expected when no tidal correlation exists. a \(N=50\) in area A; b \(N=100\) in area A; c \(N=50\) in area B; d \(N=100\) in area BBack to article page
