Abstract

Satellite data have been analyzed to identify changes that occurred in the lithosphere, atmosphere, and ionosphere before and during earthquakes with magnitudes of M = 5.0–7.0 in the Kuril–Kamchatka Arc region from May to August 2024. Anomalies in lineament systems, underlying surface temperature, outgoing longwave radiation, and the total electron content of the ionosphere have been identified for these seismic events. These anomalies have been found to manifest themselves as variations in the ratios of the total lengths of differently directed local lineaments 4–21 days before the earthquakes, antiphase oscillations and changes in the underlying surface temperature, and outgoing longwave radiation 8–10 days before the earthquakes, and a sharp increase/decrease in the relative values of the total electron content of the ionosphere, which appeared 1–10 days before the earthquakes. Relationships between changes in lineament systems, underlying surface temperature, outgoing longwave radiation, and the total electron content of the ionosphere prior to the M = 7.0 earthquake that occurred in August 2024 have been identified.
