Kamen (volcano)

Why We Chose This Article

We chose this article because it has very little information and can be massively improved. This article is also important to the area the volcano is located due to it being such a prominent geological feature. Since we are interested in researching volcanos and there isn't much information on this feature, we figured that adding onto this article would be a helpful addition to Wikipedia.

Article Evaluation

This article includes a nice short description of where Kamen is located as well as provides a couple beautiful images of the geological feature, however there is a lot that can be added to it. There is really no lead or body attached to this article, so the first thing we would want to work on is creating those to help give it a foundation. Not all of the images themselves are completely related to what the article discusses. We could add many descriptions and features of Kamen that haven't been added to give the reader a deeper visualization of what the volcano might look like. In order to give the reader a clear understanding of what the volcano is capable of, we can describe the possible impacts it could cause if Kamen were to erupt. Adding a couple more images with descriptions could also enhance the quality of the article too.

Article Draft

Lead

Kamen (Russian: Камень, literally Stone) is a dormant stratovolcano located in the southern part of Kamchatka Peninsula, Russia, flanked by Bezymianny and Kluchevskaya. It is the second highest volcano of Kamchatka.

Kamen sits above a shield volcano next to its neighboring volcanos. While the proximity between Kamen and its neighbors are relatively close, the lavas produced by all of them is different.

History

Kamen was formed over large lava plateaus in two different stages of eruptions. The first stage of eruptions was explosive and produced pyroclastic debris which mainly contained tuffs while the second stage aimed to be the opposite. This stage created lava flows which began the formation of dikes (often reaching up to 2 kilometers long and 5 meters thick) as magma moved down the volcano. These same eruption stages were also how Kamen's neighboring volcanos were formed. As Kamen continued to age, so did the compositions within its lava. When the stratovolcano was first born, the lava it would often produce would contain mafic materials. However as Kamen grew older, it started to show a decline in these minerals.

Collapses

Around 10-11K years ago, Kamen had gone dormant due to its magma supply being removed. This has later resulted in the destruction of the volcano's cone due to gravitational collapse as well as other natural occurrences. Kamen hasn't maintained much of its original structure with much of the edifice being destroyed by multiple different collapses resulting in only about 60% of that original topography to remain. These collapses created debris avalanche deposits and Toreva blocks. These blocks' layering indicate that they were once part of the volcanic cone. Another volcano has formed from southern collapse crater. This crater contains volcanic breccia called Griva and Studyonyi.

Topography

In Kamchatka, Russia, a large shield volcano houses multiple volcanoes within its lava plateau. One of these volcanoes is a dormant stratovolcano called Kamen. Near Kamen are two rivers named Studenaya and Khapitsa as well as the Kozyrevsk and Klyuchi villages. As of today, the volcano is mostly covered by a glacier, however a major landslide was able to open up the interior of Kamen which offered a new perspective of observing it's cross sections.
