Geophysical effects of the active stage of the stromboli volcano eruption on october 9, 2022

Using the results of instrumental observations carried out in the surface atmosphere, the response of the microbaric background, variations of the Earth’s magnetic and electric fields to the paroxysmal activity of the Stromboli volcano (October 9, 2022, Italy) is analyzed. It is shown that the active stage of a volcanic eruption was accompanied by the generation of an acoustic signal and pronounced variations in the geomagnetic and atmospheric electric fields at considerable distances both during the period of volcano activity and during the arrival of an infrasonic wave at the observation point. It was also noted that the volcanic eruption caused a response in the ionosphere in the form of a change in the critical frequency of the F2 layer.
