The volcanic activity on Kamchatka manifests itself periodically, that is to say, there are periods when many volcanoes become active and also there are periods of quiescence. Eruptive periods consist of cycles of eruptions of separate volcanoes. These cycles either coincide with each other, or being late, overcover one another. The existence of eruptive epochs shows that some kind of a region wide stimulating force acts upon the volcanic reservoirs.
The last eruptive period which began at the end of 1944 and apparently is not quite finished up to the present moment, consisted of cycles of eruptions of four largest volcanoes of Kamchatka, namely the volcanoes of Klyuchevskoy, Shivelouch, Avacha and Mutnovskaia.
Just as earlier, the eruptive cycle of the Klyuchevski volcanoes has again manifested itself in the form of a therminal eruption but of the main crater and the lateral one proceeding on the volcano slope.
Having begun in early December 1944, the therminal eruption gradually increased and on the 1-st of January attained its culminating intensity. This eruptive phase with its enourmous cloud of gases, ashes and red-hot bombs, 10 km up above the crater, with lightning rumbling and with dozens of seismic shocks as well as with streams of water and mud which came down to a distance of 35 km from the crater during a terrible frost, was quite an uncommon phenomenon for ordinary eruptions of the Klyuchevskoy volcano. The lateral eruption occurred on the South-Eastern slope of the volcano 5 months after the activity of the main crater had ceased. As the result of the gas and lava eruption there was formed a whole series of craters and there was an effusion of lava, having about 5.5 km in length. The study of this eruption gave a lot of interesting material, the most interesting being the oxidation procests of the lava and the genesis of fumarole gases.
The activity of the Avacha volcano lasted a comparatively shorter period of time. Its eruption began on the 25th of February 1945 and lasted 7 hours.
Just like the former eruptions this was a strong explosive activity, which resulted in the formation of an enormous cloud of gases and ashes formed about 6 km above the crater.
Following the course of the wind in the south-east, this cloud proved to be of great interest, because of its electric phenomena (lightning and St Elm fires) as well as by being strongly crarged with lava particles. The deposit of these particles had a strong admixture of pumice, was 45 cm thick and was found 25 km from the crater. When compared with the three erupitons of the former eruptive cycle, the present eruption was still more intensive.
The erupt ons of the Shivelouch volcano began at the end of December 1944, lasted throughout the whole 1945 and was still noticeable in the first part of 1946. Eruptions like single shots were feeble; there were short explosions (5—15 m) of gases and ashes occurring at long intervals. The volcanic cloud that would appear at those moments 1-2 km above the crater, was soon blown away by the wind and dispersed in the air.
The eruptions of the Shivelouch volcano and their long lasting cycle proved to be similar with the activities of an extremely complex by its structure ancient and extinguishing American volcano Lassen Peak.

Kamchatka is a volcanic region of great interest.
About 100.000 km2 are covered by recent and quaternary lavas and tuffs; there are 20 volcanoes, active and solfatoric, 109 extinct volcanoes, 68 groups of thermal springs, 17 large and many small geysers. The Klyuchevskoy volcano is the most active one with a most varied volcanic activity. Besides, it is situated at the juncture of the Kourilsk-Kamchatka and Aleutian volcanic and tectonic arcs.
This fact explains for the organization of a volcanological station in the vicinity of the Klyuchevskoy volcano.
Since the station has been in existence, i. e, sinece 1935 the following eruptions have been recorded: the explosive eruption of the Klyuchevskoy volcano in 1935, and with lava flows from April 1937 till March 1939, and with formation of a number of parasitic craters; the eruption of Avacha from March till December 1938 accompanied by the issuing of an incandescent agglomerate stream rather the kind of the avalanche of the La Soufriere, the Merapi and partly the Mont Pele; the eruption of the Ploskij Tolbachik from September 1939 till June 1941, at the end of which a parasitic cone was formed from which flows issued; a small explosion of the Zhupanov volcano in the beginning of 1940; an eruption of the Karim volcano during 1940 and in the beginning of 1943.
Owing to the almost simultaneous ejection of lava at different heigtsts and at different distances from the central conduite of the Kluchevskoy volcano S. I. Naboko could drawn a picture of the gravitative differentiation in the magmatic reservoir.
There are given temperatures of the flowing bazaltic lava taken by V. P. Popkov and I. Z. Ivanov during their remarkable drift on the crust of the lava stream as well as the composition of gases collected by them from the hot lava.
A number of other volcanological observations is also given as well as short description of the volcanological station.
The Kamchatka Station was organized by F. I. Loevinson-Lessing. Since 1940 the station has been run by A. N. Zavaritsky, who is now organizing a Laboratory of Volcanology in Moscow.
