Registering Changes in the Prognostic Parameters of the 2024 Kamchatka M = 5.0–7.0 Earthquakes from Space

Satellite data were analyzed to identify changes that occurred in the lithosphere, atmosphere, and ionosphere before and during the earthquakes with magnitudes M = 5.0–7.0 in the Kuril-Kamchatka island arc region from May to August 2024. Anomalies in lineament systems, underlying surface temperature, outgoing long-wave radiation, and ionospheric total electron content were identified for these seismic events. It was established that these anomalies were evident as variations in the ratios of the total lengths of differently directed local lineaments 4–21 days before earthquakes, antiphase oscillations and changes in the temperature of the underlying surface, as well as outgoing long-wave radiation 8–10 days before earthquakes, and a sharp increase/decrease in the relative values of the ionospheric total electron content 1–10 days before earthquakes. Relationships were identified between changes in lineament systems, underlying surface temperature, outgoing long-wave radiation, and the ionospheric total electron content prior to the August 2024 M = 7.0 earthquake.
