Aegean Tension IndexA daily escalation/de-escalation index for Cyprus, Greece and Türkiye across the Aegean and Eastern Mediterranean, from open-source indicators & warnings. A heuristic, not a forecast.

What changed · 2 Oct 2026

Military activity stayed at routine levels, with a single Turkish UAV airspace violation reported and the Oruç Reis survey continuing off north Cyprus under an active NAVTEX. The Great Sea Interconnector dispute hardened as Türkiye's defence ministry repeated it will not allow unauthorised work on its claimed continental shelf and Greek officials publicly rejected that condition, while Defence Minister Dendias used a high-profile Cyprus Independence Day visit to reaffirm support for Nicosia.

• Military posture: 5/10 · GEETHA reported a routine Turkish UAV violation (2 national airspace, 1 Athens FIR, SE Aegean) on 1 Oct; the Oruç Reis survey, escorted by three support vessels, continued off north Cyprus under NAVTEX 0953/26.
• Diplomatic / political: 5/10 · Dendias visited Nicosia for Cyprus's Independence Day pledging continued Greek support, while Greek government spokesman Marinakis and FM Gerapetritis publicly rejected Türkiye's demand for prior approval of the interconnector.
• Economic / informational: 6/10 · Türkiye's defence ministry reiterated it will not allow unauthorised continental-shelf activity; Athens rejected the condition, keeping the Great Sea Interconnector dispute at an unresolved impasse.
• EW / SIGINT: 3/10 · No GNSS jamming, spoofing or other interference incidents linked to Greece, Cyprus or Türkiye were reported in the period.
