The Ebeko volcano located in the northern part of Paramushir Island (Northern Kuril Islands), is currently the most active volcano of the Kuril Island arc: since 2016, next explosive eruption has continued, proceeding in the form of regular ash-gas explosions of moderate force. In the period from January 2018 to October of 2020 a total of at least 1834 emissions were recorded (during daylight hours and under good weather conditions). In May–July 2020, the intensification of the eruptive activity of the volcano was observed, that manifested in a sharp increase of the emissions frequency and height. During this period, 296 emissions were recorded, 90 of which were at an altitude of 3 km or more.

RUS Investigation of ancient river valleys – paleochannels – is of particular relevance for the territory of St. Petersburg and the Leningrad region due to a poor stability of rocky soils here and the subsequent high risk of structural damage during the construction of multi-storey buildings. In addition, paleochannels in the region constitute a source of renewable drinking water owing to a significant capacity of sandy sediments. The mapping and estimation of the capacity of such reservoirs may be useful for the selection and monitoring during operation of water sources feeding the nearest settlements (Sestroretsk, Solnechnoye, etc.). Since the density of the enclosing rocks is higher than that of incising sediments, paleochannels constitute areas having a relatively high thickness of low-density sediments, over which negative gravimetric anomalies can be expected. At the first stage of the study, observations along a single profile crossing the assumed position of the paleochannel under study were performed. The study was conducted using a high-precision gravimeter Autograv CG-5 with geodesic tracking. The research confirmed the efficiency of gravity survey for solving the research tasks, as well as for performing areal gravimetric observations combined with shallow seismic surveys. The anomaly above the incision under study was approximately 1 mGa. The study revealed the presence of tectonic disruptions under the paleochannel, vertically displaced respective to the underlying sediments not inherited by the modern relief. Observations, processing and interpretation of the data were performed with the participation of students from the St. Petersburg Mining University in the framework of elective classes.

To verify the ideas about neotectonic and modern stresses of Sakhalin, we analyze structural and geomorphological signs of the stress state of this region, discovered during field work in 2019–2020. Along with updated field measurements using the structural-geomorphological method, data on crustal deformation based on GPS/GLONASS measurements are presented. Data from geophysical studies (seismological and borehole methods) are given. The identification of three types of areas with different geodynamic regime: transtension, transpression and strike – slip (simple shift) is confirmed. Variations of the current stress field at the boundaries of regions with different geodynamic regime for the formation of new faults are noted. Northern Sakhalin has specific directions of compression axes of neotectonic stresses, expressed in North-Eastern orientations, in contrast to the prevailing sublatitudinal orientations on the entire island. Studies have shown that in the south of Sakhalin, the border between the Amur and Okhotsk microplates runs along the West Sakhalin fault rather than the Central Sakhalin fault.

Проанализированы материалы многолетних визуальных наблюдений за волнением на береговых гидрометеостанциях Южно-Курильск (о. Кунашир) и Малокурильское (о. Шикотан). Показано, что наибольшая интенсивность волнения наблюдается в период с октября по январь. Выявлено резкое увеличение числа экстремальных штормов в последнее десятилетие. Проанализированы материалы инструментальных измерений волновых процессов в бухтах о. Шикотан, включая экстремальные штормы 17– 18.12.2014 и 8–9.10.2015 г. На океанской стороне острова, в бухте Димитрова, выявлено существенное различие в преобладающих периодах волнения при летних (7–9 с) и осенних (9–15 с) штормах. Отмечены вариации периода спектрального максимума при экстремальном шторме 17– 18.12.2014 г. с 8–9 до 16–18 с, а затем вновь до 10 с по мере развития шторма, а также заметный вклад ветрового волнения с периодами 4–6 с, не наблюдавшийся при более слабых штормах. Обнаружены вариации спектрального максимума волнения в бухте Малокурильская, синхронные с приливом. Выявлено значительное возрастание энергии в инфрагравитационном диапазоне (30–300 с) при сильных штормах. На диаграммах текущего спектра выделяются полосы на фиксированных частотах, отвечающие резонансным периодам бухт. На фазе наибольшего развития шторма происходит стохастизация волнового поля (спектр приобретает характер белого шума, резонансные пики не выражены).

Впервые приводятся данные о физико-химических свойствах сапропелевых грязей оз. Большое Чибисанское (о. Сахалин). Отобранные в 2016 г. в восточной части озера грязи относятся к лечебным пресноводным сульфидным сапропелевым. Общий объем доступных для извлечения грязей можно оценить в 150–200 м3. Минерализация грязевого раствора в натуральных грязях составляет 0.688 г/дм3, по ионному составу исследованные грязи относятся к гидрокарбонатно-сульфатному магниево-натриево-кальциевому типу. Содержание сульфидов железа, которые являются одним из важнейших бальнеологических компонентов в грязях, составляет 0.01 % на естественную сырую грязь. В грязях обнаружены бальнеологически ценные органические вещества (2 % на естественную сырую грязь), что обеспечивает грязям высокую микробиальную активность и способствует накоплению в них биологических стимуляторов – липидов, витаминов, ферментов, гормонов.

The analysis of analytical approaches to steam chamber growth during crude oil recovery by steam assisted gravity drainage method has been represented. The numerical model which takes into account most of the assumptions applied to analytical approaches has been developed and used for the effectiveness assessment. The model includes the mass balance equations for water, steam and oil saturations, the energy conservation law with latent heat of vaporization/condensation of water as well as Darcy’s law of filtration. Computer implementation of the model is based on numerical solution to the developed system of equations by finite-element method with respect to the saturation and pressure variables. The results of numerical simulation have shown a quasi-stationary regime of the steam chamber growth in horizontal and vertical directions caused by convective flux of cold water to the interface. However, the considered analytical solutions predict a linear (or close to it) rise of the steam chamber during the whole process of heating. This can lead to the incorrect values of oil production rates on the initial stage of recovery. At the stage of vertical growth a formula which takes into account non-stationary heat flux through the steam chamber boundary gives the best qualitative agreement with numerical solution. Meanwhile a qualitative and quantitative agreement between the most considered models and numerical results has been observed when the steam chamber approached to the top of oil horizon. The analytical evaluations of its width after reaching the top have a qualitative disagreement with the results of the proposed model which predicts substantially non-linearity of the steam chamber evolution.

Превышение установленного норматива выявлено только в содержании NO2 – в водах р. Сусуя на всех пунктах ее опробования. Анализ данных о содержании органического вещества в водах показал, что свалка ТБО является источником поступления в речные воды органических форм углерода и азота. Ключевые слова: природные воды, химический состав, анионы, катионы, антропогенная нагрузка, Сахалин.","PeriodicalId":34500,"journal":{"name":"Geosistemy perekhodnykh zon","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69578075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Реферат PDF Rus The paper presents the results of modern studies of physical and chemical features of littleknown Paromay thermal springs in the north of Sakhalin Island, obtained during field works in November 2018 and October 2019. There were no significant changes in the thermal spring physical and chemical features in comparison with the previous studies of 1951 and 1953. Several thermal springs with a temperature up to 32 °C are on a small plot in the floodplain of the Paromay River. By chemical composition Paromay springs belong to fresh (mineralization up to 0.68 g/l), slightly alkaline (pH 7.3–7.5), hydrogen carbonate-chloride sodium waters. Gas composition of thermal springs mainly consists of nitrogen (61.4 %) and methane (31.6 %), which are not typical to other thermal springs of North Sakhalin, in which the methane dominates. The measurements of volumetric activity of subsoil radon–222 in the area of thermal springs do not reveal abnormal concentrations; values of OA Rn 58–83 Bq/m are comparable to other manifestations of thermal and mineral waters of the island. Computed by complex geothermal meters (Na–K, K–Mg, Na–Li, Mg–Li, SiO2) the temperatures of deep water reservoir are 30–40 °C, which corresponds to thermal spring formation depth of 1–1.5 km. Paromay thermal waters can be used as drinking water and for balneological application.
