Comprehensive data analysis of atmospheric and cyclonic activity based on worldwide meteorological and oceanology data as well as the comparison with tilts and strains precise measurements by far distanced instruments have been performed. The earlier proposed model of earthquakes triggering due to atmosphere, ocean and lithosphere interaction was confirmed. The interaction develops as successively arising hurricanes (typhoons) activity in form of spatial-temporal swings of the lower pressure areas over the tectonic plates. The process started 1–2 months before the 2023 Mw 7.8 Turkey earthquake and after some cyclones reduction, it resumed. It was at this time that a major seismic shock occurred. This study considers the cyclones interaction in the Indian Ocean, North Atlantic Ocean and Mediterranean Sea during December 2022–January 2023. Excitations of Indo-Australian, African, Eurasian and Arabian tectonic plates progressed as NW-SE spatial and temporal swings over seismogenic area and were accompanied by tilt-baric and strain-baric disturbances detected by instruments installed in Central and East Europe and Far East regions. Tilt-baric effects of 1.2 mas/hPa and strain-baric events were observed for the most intensive cyclones 2–7 weeks before the earthquake.
