Web9 nov. 2024 · In this work, the temporal variations in the ionospheric F region current (FRC) during the 2024 volcanic eruption in Tonga are reported for the first time. The FRC … WebThese variations are also evident in GIM maps over the Awaran EQ epicenter. The findings point towards a large emission of EQ energy before and after the main shock during quiet storm days, which aid in the development of lithosphere ionosphere coupling.
