Sheveluch volcano is the most active volcano in Kamchatka. The paroxysmal explosive eruption of the volcano that destroyed the lava dome in the volcanic crater continued on April 10–13, 2023. According to various satellite data, the height of the separate eruptive clouds probably exceeded 15 km a. s. l. A powerful cyclone, which dominated the entire Kamchatka Peninsula, pulled the eruptive cloud to the west, turned it to the south, stretched it to the north and directed it to the east from the volcano. The dynamics of the development of ash and aerosol clouds of this eruption is reflected in the animations made from a series of Himawari-9 satellite images in the VolSatView IS from 08:00 UTC (Coordinated Universal Time) on April 10 to 07:50 UTC on April 14 (http://d33.infospace.ru/jr_d33/materials/2023v20n2/283-291/1683110898.webm) and of the Arctica-M1 satellite from 16:00 to 21:30 UTC April 10 (http://d33.infospace.ru/jr_d33/materials/2023v20n2/283-291/1683821166.webm). It was noted that the eruptive column was not vertical: for example, at the initial moment of the eruption on April 10 at 13:20 UTC, it deviated to the north-northeast, on April 11 at 12:00 UTC to the northwest, and on April 12 at 07:00 UTC to the southwest. During the paroxysmal eruption, sulfur dioxide continuously entered the atmosphere, the maximum amount of which was released on April 10–11, as a result of the explosive destruction of the lava dome of the Sheveluch volcano. Ash clouds along with aerosol clouds on April 10–13 were stretched into a strip more than 3500 km long from west to northeast. On April 21–22, the Sheveluch aerosol cloud was observed in the region of the Scandinavian Peninsula. The total area of the territory of Kamchatka and the Pacific Ocean where ash and aerosol plumes and clouds were observed during the April 10–13 eruption was about 3280 thousand km2. The paroxysmal eruption of Sheveluch volcano belongs to the sub-Plinian type because it is characterized by a big height of eruptive cloud and a long event duration. For this eruption, the VEI (Volcanic Explosivity Index) is estimated to be 3–4. A detailed description of the paroxysmal explosive eruption of Sheveluch volcano and the spread of the eruptive cloud was performed based on data from various satellite systems (Himawari-9, NOAA-18/19, GOES-18, Terra, Aqua, JPSS-1, Suomi NPP, Arctica-M1 etc.) in the information system “Remote monitoring of the activity of the volcanoes of the Kamchatka and the Kuriles” (VolSatView, http://kamchatka.volcanoes.smislab.ru).

The 2020–2022 field works gave results that were used as a basis for describing the geological structure and whole-rock compositions for Kronotsky Volcano, one of the least known eruption centers in the East Volcanic Belt (EVB), Kamchatka. The stratovolcano edifice was estimated to be 350 km3 in volume, which is much above the respective figures for the other stratovolcanoes in the EVB frontal zone. The rocks are low-K and high-Fe tholeiitic basalts and basaltic andesites (SiO2 = 47.04‒53.15 wt %; K2O = 0.24‒0.65 wt %; FeO*/MgO = 1.2‒2.89). The basalts have extremely low concentrations of silica, potassium, titanium, and phosphorus compared with the rocks of the other frontal volcanoes in Kamchatka. The petrochemical differences thus identified were used to more accurately classify structures situated at the junction between the nearby Kronotsky and Krasheninnikov volcanoes. The acquired data will make the basis for further petrologic and geo-
chemical characterization of the volcano, as well as being possibly used for reconstructing the sequence of volcanic events in the area of study, including a more accurate history of the formation of Lake Kronotsky.

In July-August 2023, field work was carried out on the northern slopes of Kronotsky volcano in the territory of the Kronotsky State Reserve, which is rarely visited by researchers. The aim of our work was to sample lavasthat build the volcanic edifice in this sector, and also to search for traces of the volcano’s explosive activity in the Holocene. This report lists and illustrates interesting findings and the main results of the work. In particular, lava flows, dikes and pyroclastic horizons were sampled at altitudes ranging from 780 to 2200 m; several cinder and lava cones were discovered; samples of cognate inclusions and xenoliths were found. Inaddition, Holocene soil-pyroclastic sections, presumably containing tephra horizons from Kronotsky volcano, were documented in detail and sampled.
