During the multiyear monitoring of particle fluxes and near-surface electric field (NSEF) on the Aragats research station, no runway relativistic electron avalanches have been observed in the January-February months. The large peaks and energies of TGE particles originating from the electron-gamma avalanches in the thundercloud are observed in the Spring-Autumn months when the electric field inside the cloud often exceeds the runaway threshold strength. On February 7, 2023, suddenly, all particle detectors registered 3 TGEs within 10 hours without any unusual local weather conditions. We consider these TGEs as indirect evidence of the influence of strong earthquakes on the previous day on the ionosphere and via the ionosphere on the structure and strength of the intracloud electric field above Aragats mountain. Recovered energy spectra of TGE electrons and gamma rays prove nearly one hour the strength of the electric field above Aragats at the heights 3300-5300 m comprises 2.1 kV/cm. |
