Parasitic craters that appeared in 1932 at the foot of Klyuchevsky volcano in Kamchatka

Abstract

In the summer of 1932, it was known about the formation of a parasitic crater at the foot of the Klyuchevsky volcano. Upon arrival in Petropavlovsk, it turned out that a second parasitic crater had formed there, which at that moment was in activity. The work plan was changed, and the author immediately went to the Klyuchevsky volcano. New parasitic craters formed in the town of Kirgurich. From the village of Klyuchi they are located 16 kilometers S, and 20-25 kilometers NE from the top of Klyuchevsky volcano. In total, two craters appeared. The first is named Kirgurich, after the name of the area, the second is Tuila. Kirgurich is located near the end of the birch forest zone at altitude. high no higher than 600 m. Tuila arose later than Kirgurich and is located to NHE 1300 m from it at abs. high 500-530 m. But abs. marks among all the parasitic craters E and N of the Klyuchevskaya slope, the new craters are located the lowest. New parasitic craters are located on the same line with the Kharchinsky and Zarechny volcanoes, on the one hand, and old parasitic craters located S from the new ones, on the other. On this line, the new craters are closest to the old parasitic craters.
