Figure 6From: Regional and global variations in the temporal clustering of tectonic tremor activityDistributions of Ï„ c for Shikoku with the different bin sizes and extracted time spans. (a) Distributions of Ï„ c with bin radii of 5Â km (bottom), 10Â km (middle), and 15Â km (top). (b) Distributions of Ï„ c with extracted time spans of 1Â year (bottom), 2Â years (middle), and 3Â years (top). (c) Example of the variation in Ï„ c for different time frames and the different time spans applied. The top panel shows the cumulative events for the subset in Shikoku, with a nonperiodic burst between 5.9 and 7Â years induced by a long-term slow-slip event. The upper and lower color bars show the temporal distributions of Ï„ c determined using the 1- and 2-year time spans, respectively, with respect to the time frame corresponding to the cumulative events.Back to article page
