Fig. 4: Diffusive migration of tremors impeded by the strike-slip faults.
From: Structural barriers control the spatial extent of slow earthquake slip
Tremor probability calculated from tremors during a first and b second diffusive migrations are shown by the heat map. Geological interpretation is depicted using the same notation as that used in Fig. 2b, including the strike-slip faults represented by subparallel black lines. The position of the subducted Paleo–Zenisu ridge (red-shaded area) is based on ref. 40 and is reproduced with permission from Elsevier. c Time–distance plot of tectonic tremors along the green dashed line shown in (a) and (b). The dots represent tremors, where the red and orange dots are those used to calculate the probability maps shown in (a) and (b), respectively, while the gray dots indicate tremors that are not included in either calculation. The error bars in (c) depict the range of the 95% confidence interval. The blue dashed parabola delineates the diffusive migrations of the tremors.
