“…There are several works discussing GIC in the Japanese area [e.g., Watari , ], but it is not considered to have a significant impact on the electric grid in Japan, which is located in the middle and low geomagnetic latitudes. However, some recent studies [e.g., Fujita et al ., ] mention that GIC is potentially critical in several local areas even in low‐latitude Japan if heterogeneous ground resistivity is considered.…”

“…Many countries in the world already have reliable ways to predict the appearance of geomagnetically induced currents in the electric power system (e.g. Fujita et al, 2016), but Kazakhstan, which has many power transmission lines and pipelines, needs its own strategy to mitigate the effects of GIС, taking into account ionospheric currents, soil conductivity, and the spatial direction of main lines. For Kazakhstan, which has a territory of 2 725 000 km 2 , where the long trunk power lines, long During periods of geomagnetic storms, corpuscular eruptions occur, mainly of electrons, as well as protons, from the radiation belts of the Earth.…”

“…Extreme solar events, such as solar flares accompanied by the release of a strong coronal mass ejections, CMEs, cause perturbation of the Earth's magnetic field. One of the negative effects of extreme solar events on technological systems is emergence of geomagnetically induced currents (GICs) in conductive ground systems, such as power lines, and pipelines (Bailey et al., 2022; Fujita et al., 2016; Gannon et al., 2019; Kappenman, 2005). Among the potential adverse effects of GICs are the occurrence of short circuits, equipment damage, and disruption of power systems.…”
