The earthquake in western Turkey on October 27–28, 2025 had its epicenter near the town of Sindirgi in Balıkesir Province, about 5–8 kilometers south- southwest of Bigadiç, depending on the reporting agency. The event was widely felt across the Marmara region, including Istanbul, Bursa, Manisa, and İzmir, with aftershocks following the initial quake.
Key details
- Location: Sindirgi district, Balıkesir Province, Turkey. Some updates place the epicenter around Sindirgi, with reported coordinates and regional mappings from seismological agencies.
- Magnitude: Reported around 6.0–6.1 Mw (varies slightly by agency and moment magnitude calculations).
- Depth: Shallow rupture depths reported in several updates (roughly a few to around 6 km in various feeds).
- Impact: Buildings collapsed in Sindirgi and surrounding areas; injuries reported and evacuations in some towns; widespread shaking felt in Istanbul and western provinces. No confirmed large-scale casualties reported in early updates, though assessments continued.
- Aftershocks: Aftershocks followed the main event, with ongoing monitoring by AFAD and local authorities.
Context and context notes
- This sequence followed a prior August 2025 quake in the same Balıkesir region (Sindirgi area), which had already caused damage, and the late-October event compounded anxiety in the region.
- The Balıkesir region lies near major fault lines, making it prone to recurrent earthquakes, a known characteristic of this area.
What to know if you’re in the area
- Stay alert for aftershocks and follow guidance from local authorities and emergency services.
- If you’re in a damaged building, move to a safe open area away from structures and utility lines after shocks.
- Check for injured people, provide first aid where trained, and contact emergency services for non-life-threatening needs.
