Figure 3. The spatial distribution of earthquakes and their aftershock activity in the vicinity of the Sındırgı Fault. (a) After the August 10, 2025 magnitude 6.1 earthquake, aftershock activity migrated to the southeast. (b) The October 27, 2025 magnitude 6.1 mainshock occurred in the area in which the initial event’s aftershocks were concentrated. (c) On January 23, 2026, a magnitude 5.1 aftershock occurred in the second mainshock’s aftershock zone. The time-dependent variation characteristics of this seismic activity are shown in Figure 2. The figure was prepared by using the ZMAP7.1 algorithm (Wiemer, 2001) in MATLAB (2025). Credit: Eyidoğan, 2026, CC BY-NC-ND 4.0
