The April 11, 2023 Catastrophic Explosive Eruption of Sheveluch Volcano, Kamchatka
This paper provides data on the April 11, 2023 eruption of Sheveluch Volcano. The impact of the eruption has been assessed. The directed explosion destroyed the lava dome which took over 42 years to grow. According to the data acquired just before the eruption, the lava dome had a volume of about 0.53 km3. The eruption produced a field of explosive ejecta ∼70 km2 in area and 0.49 km3 in volume. The directed explosion was accompanied by pyroclastic flows which traveled for distances of 25–30 km from the volcano. The associated ashfall had a length of over 200 km. The weight of an ash sample varied between 1.2 and 43.9 kg/2, depending on the distance to the volcano. The area of ash deposits (with the weight of ash samples over 50 g/m2) was about 17 thousand m2, the volume of the ash deposits was 0.09 km3. Considered in relation to the total volume of ejecta (over 0.60 km3), the April 11, 2023 eruption of Sheveluch should be termed a great catastrophic eruption of this century.
期刊介绍：
Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
