[en] Geo-dynamic information is provided by the sections of geological cycle sciences. Global safety determines the peculiarities of the planet's existence and considers the geological system of the Earth; man-made safety in engineering geo-dynamics assesses the stability of buildings and structures in the manifestation of endogenous and exogenous geological and engineering-geological processes; ecological safety in ecological geo-dynamics is related to the consequences of the manifestation of processes of different genesis in the abiotic spheres of the Earth for biota, including humans. The consequences of the largest eruption of the Shiveluch volcano that occurred in Kamchatka in the spring of 2023, which violated the man-made and ecological safety of the region, are presented.
