Activity of Turkey’s Internet Community before the Istanbul Earthquake

Aleksandr V Tertyshnikov* and Dmitry S Obelchenko

The activity of the Istanbul internet population before a nearby earthquake with a magnitude of 6.3 on 23 April 2025 was evaluated using search-engine queries for the term “su” (Turkish “water”). This term has previously demonstrated informative behavior in diagnosing seismic hazard in different regions. The morphology of amplitude diagrams for the dynamics of the term’s popularity was analyzed. The informational precursor was expressed through dominant periods of 3, 4, 6, and multiple periods of 12 days. These features indicate the presence of a sensory-information response in the behavior of internet users during seismic hazards.
