(a) Percentage of earthquakes with positive ΔCFF among all of the earthquakes with significant changes in each 0.3-degree grid square for a depth of 0 to 30 km. The red (blue) regions are expected to be activated (deactivated) by the ACFF due to the Tohoku-oki earthquake. The grid squares surrounded by thick lines indicate that more than 100 focal mechanism solutions are available. (b) Percentage for a depth of 30 to 100 km. (c) Epicentral distribution during the three weeks after the mainshock (M ≥ 1.0, depth ≤ 30 km). The rectangular regions (A–D) indicate regions where the earthquakes were extracted for Fig. 4. (d) Epicentral distribution during the three weeks after the mainshock (M ≥ 1.0, 30 km < depth ≤ 100 km).
