| Summary: | Electrostatic fluxmeters are in operation at three sites in the region of Central Kamchatka depression to record the atmospheric electrical potential gradient (PG). PG diurnal variations for these sites are compared with those of «Paratunka» observatory (PRT) located on the Eastern coast of Kamchatka peninsula. Cases of the response in AEV V′ dynamics on eruptive cloud passage, occurring during Shiveluch volcano explosive eruptions, are described. Negative polarity signals with the maximum values up to 5 kV/m were recorded in the near-field zone (< 50 km) during ash fall. Positive polarity signals were recorded in the far-field zone (> 100 km). Recording of signals in PG occurring during eruptive cloud passage may be one of the components of complex observations over volcanic eruptions2**. |
