Changes in stress and slip rate estimated at H1 on the plate interface caused by tides and non-tidal variations in ocean bottom pressure (OBP). a A comparison in peak-to-peak amplitudes in ΔCFS between solid earth and ocean tides on Jan. 1, 1980, along the red line in Fig. 1b. b, c The red and blue lines denote ΔCFS caused by ocean tides and that caused by the sum of solid earth and ocean tides, respectively. d, e Hourly, daily, and monthly slip rates calculated using Eq. (1) with ΔCFS being caused by the sum of solid earth and ocean tides shown in (c). f ΔCFS caused by the non-tidal variation in OBP in Fig. 3b. The spatial distribution of OBP near the coast was considered in computing ΔCFS at H1. g, h Hourly, daily, and monthly slip rates calculated using Eq. (1), with ΔCFS being caused by the sum of solid earth and ocean tides and the non-tidal (NT) variation in (f). i, j The same as (f, h), but the horizontal axis denotes months, and the results from 1980 to 2013 are cyclically superimposed
