The paper presents summary data on the historical activity of Ivan Grozny volcano (Iturup Island, Kuril Islands), including results our own studies solfatar-hydrothermal and eruptive since 2004. Using modern analytical methods, we obtained chemical composition rocks pyroclastics explosive eruption in 2012–2013. varies from andesites to daciandesites medium potassium series. Pyroclastics 2012–2013 corresponds with content terms bulk composition. material glasses according microprobe is much...

Abstract Since 2002, complex studies of all known thermal springs Kunashir Island have been carried out. Of the four active volcanoes in island, three stable hydrothermal systems. In addition to volcanoes, are found on coast and they associated with tectonic faults. Despite different morphogenetic types their activity, common patterns zoning hydrochemical waters typical for volcano-hydrothermal On periphery extrusive domes there solfataric fields outputs gases acid sulfate hydrotherms...

The paper presents the results of modern studies physical and chemical features littleknown Paromay thermal springs in north Sakhalin Island, obtained during field works November 2018 October 2019.There were no significant changes spring comparison with previous 1951 1953.Several a temperature up to 32 °C are on small plot floodplain River.By composition belong fresh (mineralization 0.68 g/l), slightly alkaline (pH 7.3-7.5),hydrogen carbonate-chloride sodium waters.Gas mainly consists...

The paper provides with the research results of physicochemical and balneological properties thermal waters hydrothermal mud Ebeko volcano (Paramushir Island, Kuril Islands). To assess recreational tourist potential, we sample most intensive outputs. Ultra-acidic spring no. 1 Verkhne-Yuryeva group has a temperature 88 °C, its mineralized (M – 13 g/l) chloride-sulfate contain biologically active elements in elevated concentrations (Si, B, Br, Fe2 +). Thermal springs can be roughly attributed...

Different types of groundwater manifestations occurring on modern structure the Baransky volcano were studied. Volcanic and seismic activity influences strongly hydrology hydrochemistry watershed Sernaya river. Three fluids have been established: volcanic-heated, steam-heated mature. Existing model hydrothermal system was confirmed using geothermometry hydrochemical calculations. Thus is a complex object with atmospheric recharge, deep diorite body as heat source thick fractured altered...

The tectonic, geological and hydrogeological features of the south Sakhalin Island have been considered in connection with assessment possibility placing CO 2 aquifers. It has found that at regional zonal level criteria, this territory can be classified as unpromising one. concluded implementation landfill projects for placement aquifers will face great risks drinking water supply to population, also lead serious environmental consequences nature, including a shift balance aquatic ecosystem...

Abstract Within the watercourse valleys of geothermal zones, where manifestations gas-hydrothermal activity are noted, processes relief formation accompanied by chemical and thermal effects. Thermal waters contribute to specific accumulative landforms both directly in channel bottom on sides river valleys. Similar phenomena have been studied draining slopes Mendeleev volcano (Kunashir Island), Baransky (Iturup Mutnovsky Uzon-Geyzernaya caldera (Kamchatka). The typification forms is carried...

This communication, based on satellite data and the results of visual observations, considers main features activity Chirinkotan Sarychev Peak volcanoes in 2021. In period from August 8 to 23, 2021, a moderate explosive eruption volcano took place. During this time, 11 volcanic explosions were recorded at an altitude 1.5 4.5 km a.s.l. The parameters 2021 similar previous eruptions 2013–2015, 2016, 2017. At June 29, July 1, 6 November 26 single relatively weak ejections about 2.2–3 recorded....

Abstract The article presents the results of researches thermal waters South-Eastern solfataric field Ushishir volcano (Yankicha Island, Central Kurile Islands) in 2007 and 2015. Detailed studies physicochemical properties hydrothermal springs were begun 1950-60 years. Modern have confirmed stability physical chemical parameters hydrotherms. (temperature up to 100 °C), as before, can be attributed acidic (pH 2.8-3.6), highly mineralized (TDS 23-36 g/l), sodium chloride. composition ratio...

Original data on the isotopic and chemical composition of mineral waters, cold ground surface as well hydrogenic deposits Antonovsky manifestation hydrogen sulfide waters (the coast Tatar Strait, Sakhalin Island) are provided in article. For first time, content oxygen isotopes groundwaters volumetric activity radon rare-earth elements were obtained. Based automatic monitoring physical parameters their hydrogeological characteristics determined balneological properties assessed. It has been...

Abstract For the first time, paper presents results of a detailed hydroacoustic study basin Biryuzovoe Karyernoe Lake (Novikovo village, Korsakovsky District, Sakhalin Region), formed after conservation germaniferous coal deposit same name. On basis 12 profiles, bathymetric scheme lake was compiled, its main morphometric parameters were calculated, and morphological appearance described. Preliminary conclusions have been made about rates sedimentation within lake, perspective points for...

RusFirstly, the data on physical and chemical properties of sapropel mud morphology bottom several freshwater lakes central part Elizovo district Kamchatka have been represented.The Ovalnoe Sinichkino (district Petropavlovsk-Kamchatsky sity), Lesnoe lake Paratunka village) unnamed 2.5 km south Malki village were explored in 2016.The aim research was to study features sapropels assess prospects for balneotherapeutic cosmetological use.The area most promising among surveyed.Physical indices...

The paper presents the results of studies (2017 and 2019) physicochemical characteristics thermomineral waters Daginsky field, obtained before reconstruction springs in 2019–2020. data were compared with from previous years (1958–2014) order to study dynamics measured indicators over time. It was found that field are characterized by constancy chemical composition reservoir temperatures calculated means hydrochemical geothermometers.
