Fig. 2From: Temporal variation in seismic moment release rate of slow slips inferred from deep low-frequency tremors in the Nankai subduction zoneTemporal variation in cumulative apparent moment (left axis) and in the cumulative seismic moment (right axis) estimated from DLF tremors (black line) in each region. Gray hatched zones show the period of long-term SSEs in the Tokai region (Ozawa et al. 2016), in the Kii channel (GSI 2016), and in the Bungo channel (Hirose and Obara 2005; Hirose et al. 2010a; Ozawa et al. 2013; Ozawa 2017). A vertical dashed line represents the occurrence of the 2011 Tohoku earthquakeBack to article page
