Kamchatka River Turns Dark Brown after Shiveluch Volcano Eruption

In April this year there was an eruption of volcano Shiveluch in Kamchatka, which affected the state of the Kamchatka River. After the ashfall, the river became dark brown in color due to changes in its chemical composition. Scientists from the Ilyichev Pacific Oceanological Institute of the Far Eastern Branch of the Russian Academy of Sciences studied water samples and found that the river was enriched with mineral nitrogen and phosphorus compounds, which are important elements for living organisms.

Satellite images show that the water in the river has become turbid and phytoplankton blooms have started to form around it. Experts note that this phenomenon is not detrimental for Kamchatka shores.

Nevertheless, scientists emphasize that it is too early to make final conclusions about the consequences of the eruption for the river. The Institute plans to continue to monitor the state of the water and conduct a comprehensive marine expedition in the summer of 2023.

Volcanic eruption Shiveluch began on April 11 and lasted several days. The volcano threw ash to a height of up to 20 kilometers and an ash cloud formed within a radius of several tens of kilometers from the volcano
