Crater Lake Kipyashchee in the Caldera of Golovnin Volcano: Water and Gas Geochemistry, Output of Magmatic Volatiles (Kunashir Island)
Lake Kipyashchee ~4.6 ha in area whose greatest depth is 25 m fills an explosion crater near an extrusive dome in the Golovnin caldera. The lake water is ultra acid (рН 2.2–2.5), is of the chloride–sulfate type with a salinity of 2.0–2.2 g/L. The water temperature varies between 30 and 100°С at the surface, with the mean value being 37°С. The lake emptied itself via Protoka into Lake Goryachee at a rate of 120 L/s in August 2021. The hydrothermal drainage of magmatic Cl and S (in the form SO4) from Lake Kipyashchee is 10 and 5.4 t/day, respectively. The first ever estimate of the total diffusion output of carbon dioxide from the surface of Lake Kipyashchee is over 5.4 t/day. The geochemical data acquired during the 2020–2021 field surveys indicate an increase (compared with 2015) in the hydrothermal activity in the Golovnin caldera.
期刊介绍：
Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
