Magnetic and Ionospheric Effects of the Shiveluch Volcano Eruption on April 10, 2023

Using the results of instrumental observations made at the INTERMAGNET network and at the ionospheric sounding station “Wakkanai”, it is shown that a strong eruption of the volcano Shiveluch of an effusive-explosive nature, which occurred on April 10, 2023, was accompanied by variations in the Earth’s magnetic field, as well as changes in the critical frequency of the ionosphere F2-layer.
