Fig. 5From: Statistical study on the regional characteristics of seismic activity in and around Japan: frequency-magnitude distribution and tidal correlationProbability density distributions of each index value. Numbers in square brackets in the legend indicate the number of estimated index values. a, b \(b\); c, d \(\eta\); e, f \(D\). Left, area A; right, area B. The black lines in a–d are the distributions expected from the GR law where the true value of \(b\) is constant at 0.9. The black lines in e and f are the distributions expected when no tidal correlation existsBack to article page
