Figure 1. The location of the 205-kilometer-long Simav fault zone. The area marked with a dashed black rectangle in the upper left corner demarcates the area examined in this article, the Sındırgı segment. Fault information is taken from Emre et al. (2018) and the MTA (2025). The star shown within the area outlined by the dashed line indicates the location of the earthquake with a surface wave magnitude (Ms) of 5.4 that occurred on the Sındırgı Fault on October 28, 1942 (AFAD-DAD, 2025b). In the inset on the upper right, which is a map of Turkey’s active faults, the blue rectangle shows the location of the Simav fault zone. Credit: Eyidoğan, 2026, CC BY-NC-ND 4.0
