Resuspended ash is common in the areas of active volcanism and can be dangerous for ecosystems, human being and animals, different means of transport including local aviation. According to KVERT scientists data, a formation of resuspended ash plumes on Kamchatka occurs in the area of Sheveluch volcano annually, mainly from August to mid-October within two days. For example, these plumes observed on August, 3, 2011, September, 15–16 and October, 3–4, 2015, September, 28–29 and October, 2–4, 2016. Dense ash plumes rising 3 km above the surface to a.s.l. and 16–22 km in width drifted 600 km to the south-east from the volcano. Analysis of various satellite data in the VolSatView information system revealed typical features of Sheveluch resuspended ash plumes. The largest concentration of ash particles is observed in ash plumes at a distance of 60–70 km from the volcano; its width on the land for over 100 km reaches 16–22 km and is 1–2 km thick from the earth’s surface; a wide ash-rich plume is retained in the atmosphere from 3–5 hours to several days.

Эксплозивные извержения вулканов являются наиболее опасными в мире в связи с высокой энергетикой вулканогенного процесса и их непредсказуемостью. Для обеспечения безопасности населения при извержениях необходимо проведение вулканологами комплексного мониторинга вулканов с использованием данных всех доступных видов наблюдений (дистанционных и наземных инструментальных средств, метеоинформации). Созданная в 2011-2015 гг. совместными усилиями специалистов ИВиС ДВО РАН, ИКИ РАН, ВЦ ДВО РАН и ДВ НИЦ Планета ИС “Дистанционный мониторинг активности вулканов Камчатки и Курил (VolSatView)” ориентирована на непрерывный мониторинг вулканической активности Камчатки и Курил и анализ влияния извержений на окружающую среду.

Kamchatka and the Kuril Islands are home to 36 active volcanoes with yearly explosive eruptions that eject ash to heights of 8 to 15 km above sea level, posing hazards to jet planes. In order to reduce the risk of planes colliding with ash clouds in the north Pacific, the KVERT team affiliated with the Institute of Volcanology and Seismology of the Far East Branch of the Russian Academy of Sciences (IV&S FEB RAS) has conducted daily satellite-based monitoring of Kamchatka volcanoes since 2002. Specialists at the IV&S FEB RAS, Space Research Institute of the Russian Academy of Sciences (SRI RAS), the Computing Center of the Far East Branch of the Russian Academy of Sciences (CC FEB RAS), and the Far East Planeta Center of Space Hydrometeorology Research (FEPC SHR) have developed, introduced into practice, and were continuing to refine the VolSatView information system for Monitoring of Volcanic Activity in Kamchatka and on the Kuril Islands during the 2011–2015 period. This system enables integrated processing of various satellite data, as well as of weather and land-based information for continuous monitoring and investigation of volcanic activity in the Kuril–Kamchatka region. No other information system worldwide offers the abilities that the Vol-SatView has for studies of volcanoes. This paper shows the main abilities of the application of VolSatView for routine monitoring and retrospective analysis of volcanic activity in Kamchatka and on the Kuril Islands.

Explosive volcanic eruptions are the most dangerous in the world due to the high energy of volcanic processes and their unpredictability. In order to ensure the population safety during eruptions, volcanologists are necessary to conduct comprehensive monitoring of volcanoes using data from all available types of observations (remote sensing and ground-based tools, meteorological information). In 2011-2015, the joint efforts by experts IVS FEB RAS, SRI RAS, CC FEB RAS and FEC SRC Planet was created the information system "Remote monitoring of active volcanoes of Kamchatka and the Kurile Islands (VolSatView)", focused on the continuous monitoring of volcanic activity of Kamchatka and the Kurile Islands and the analysis of eruptions impact on the environment. The paper provides a brief description of its capabilities for a comprehensive analysis of the Kamchatkan volcanic eruptions.

In the past six decades in Kamchatka it worked great galaxy of scientists (experts), which has developed a number of original methods for monitoring and predicting volcanic eruptions, based on which was issued a number of spectacular short-term forecasts eruptions for volcanoes: Great Tolbachik Fissure in the years 1975-1976, by-Kliuchevskoi in 1983, Shiveluch in 2001, Kizimen in 2009, Bezymiannyi in 2001-2012 and etc. Detailed analysis of the obtained Kamchatka rich experience will enhance the efficiency of forecasting natural disasters.

Приведены новые данные по геохимии термальных вод Кошелевского вулканического массива на юге Камчатки. Рассмотрены условия формирования термальных вод, возможные варианты теплового и глубинного вещественного питания Кошелевской гидротермальной системы и предложена ее концептуальная модель.
