From: Recurrence intervals for M > 7 Miyagi-ken-Oki earthquakes during an M ~ 9 earthquake cycle
Cumulative slip in the middle segment before and after an M ~ 9 earthquake. a Cumulative slip from 1993–2021 estimated from observed repeating earthquake groups within each rectangle. Vertical line: time of 2005 off Miyagi and 2011 Tohoku-Oki earthquakes. b Location of each rectangle. Crosses: locations shown in (c). c Simulated cumulative slip time series over 30 years (from T′ = − 19 years to T′ = 11 years) in Cycle 3. Points at crosses in regions a1, a2, a3, b1, b2, and c1 shown in (b) were used. The behavior within each rectangle was represented by the points marked with crosses. Solid lines: from T′ = − 19 to 0 years. Dotted lines: from T′ = 0.2 to 11 years by subtracting the slip due to the M ~ 9 earthquake. The horizontal axis (T′): 0 years at the time of the M ~ 9 earthquake. Dashed gray lines: slope at Vpl. Vertical lines: time of M > 7 and M ~ 9 earthquakes. d Enlarged view of (c) at point b1.
