Volcano on Kamchatka led to increased acidity of water in rivers

The eruption of the volcano in Kamchatka Flat Tolbachik led to increased acidity in rivers near the giant, told RIA Novosti on Wednesday, a representative of the Institute of Volcanology and Seismology.

Flat Tolbachik began erupting on 27 November. In the area of the southern slope during helicopter overflights volcanologists found two fractured breakthrough emission of lava. Roar from the eruption Tolbachik in the first days of the eruption could hear the residents of nearby villages. According to eyewitnesses, in the vicinity of the volcano vibrating glass windows, electric wires, water in reservoirs. The lava flow from the top break was more than 6 miles from the lower — 13.6 kilometers. Periodically over Tolbachik ash column rises.

"The air in the area of the eruption is saturated with sulfur dioxide and fine ash slurry. Based on the results of measurements, pH level of the water in the rivers (near the volcano) reached five — became acidic," — said the source.

The normal pH level of the water in the rivers is about seven.

Condition monitoring of water and air in the settlements in the area of the eruption (Kozyrevsk villages, the May, Keys, Lazo and Atlasova) leads CPS.

"Accredited Laboratory Centre been measured concentration of harmful substances in the air in the zone of influence of emissions of volcanic gases from the volcano Flat Tolbachik. According to laboratory tests, the concentration of harmful substances in the air in the village do not exceed the maximum allowable concentration" — note in the regional management Rospotrebnadzor.

Are currently under laboratory investigation of samples of drinking water.

The last eruption of the volcano Tolbachik called Great Tolbachik Fissure Eruption, occurred in the years 1976-1976 and was the first in the history of Russian science, predicted with complete accuracy. The eruption changed the topography of the surrounding area was the cause of a local ecological disaster, which killed all living at a distance of tens of kilometers from the volcano.

Tolbachik consists of two volcanoes — Flat Tolbachik (3.085 thousand meters altitude) and acute Tolbachik (3.682 thousand meters). The nearest town — City Keys — removed from the foot of the volcano 60 kilometers.
