History of a Volcano: Klyuchevskaya Sopka
Without a doubt, the mainThe sight of the Kamchatka Peninsula is Klyuchevskaya Sopka, which is a large active volcano of a cone-shaped regular shape. If we talk about the origin of the name, then the term "hill" is interpreted by the locals as a hill or a hill. The name of the mountain is associated with the nearby river Klyuchevka and the settlement of Klyuchi. Presumably, the choice of the name of the volcano was also influenced by the presence nearby of a large number of keys that are hot. Klyuchevskaya hill is covered with a glacial cap. Some of its languages go down almost to the foot of the mountain.
For the first time the eruption of this volcano is documentedwas recorded in 1697, and the first detailed description dates back to 1737. Then the participant of the second Kamchatka expedition under the leadership of Bering Stepan Krashennikov noted that the ferocious, terrible fire lasted about a week. Because of him, the whole mountain turned into a red-hot stone, and the flame with the strongest noise rushed down in the form of a red-hot river. Klyuchevskaya Sopka significantly increased its activity in the summer of 1966. Then, during a series of eruptions, the lava descended into the valley of the Kirgurich River, along which it had long flowed in the direction of the settlement of Klyuchi. For two months, the lava flow overcame a distance of ten kilometers, which greatly frightened the locals.
Over the past more than two hundred years of observationseruptions of the Klyuchevskaya volcano occurred about fifty times. In the twentieth century, the volcano was the most active in January 1980. On the slope of the mountain there was then a crack about one kilometer in length, from which a huge amount of ash and lava was emitted.
Regarding the height of the volcano specific answernot yet. According to most atlases this parameter is 4688 m. However, in many books and encyclopedic reference books the figure is 4750 m. Based on the data of the popular Internet source Wikipedia, Klyuchevskaya Sopka has a height of 4649 m. The explanation for all this is quite simple. The fact is that the volcano is now operational. Like any other living being, he has a tendency to constantly change his size. If you study historical statistical information, you can see that, as of 1978, the height of the mountain was 4750 m. Twenty years later Klyuchevskaya Sopka increased in height by one hundred meters. As a result of the eruption that occurred in 1994, due to the growth of the slag cones, the mountain rose to 4822 m. Despite this, the active activity of the volcano led to a gradual destruction of cones and a reduction in altitude to a mark of 4750 m. Today, in the crater of the volcano again there is an accumulation of material, which leads to its growth. In this regard, the height of the mountain is now about 4800 m.
The first officially registered ascenton the volcano Klyuchevskaya hill is dated 1788 year. It happened in the period from 4 to 8 August. Then the Russian expedition, headed by Billings, approached the base of the mountain, and the curious mountain conductor Daniel Gauss, along with several of his companions ascended to the top of the volcano.
