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). В 2011-2015 гг. совместными усилиями специалистов ИВиС ДВО РАН, ИКИ РАН, ВЦ ДВО РАН и ДВ НИЦ «Планета» была создана информационная система “Дистанционный мониторинг активности вулканов Камчатки и Курил (VolSatView)”, ориентированная на непрерывный мониторинг вулканической активности Камчатки и Курил и анализ влияния извержений на окружающую среду.

In 2016, five from thirty active volcanoes erupted in Kamchatka (Sheveluch, Klyuchevskoy, Bezymianny, Karymsky, and Zhupanovsky) and three from six active volcanoes in the Northern Kuriles (Alaid, Ebeko, and Chikurachki). Effusive volcanic activity was noted at Sheveluch, Klyuchevskoy, Bezymianny and Alaid. All the volcanoes produced explosive activity. Strong explosive events occurred at Sheveluch mainly from September till December. Moderate ash emission had accompanied of Klyuchevskoy’s eruption through March till November. Explosive activity at Karymsky, Zhupanovsky, Alaid, and Chikurachki volcanoes was observed mainly in the first half of the year. The total area covered by ash in 2016 was estimated 600,000 km2,...

As the dome particles propagate from the source, they break apart by internal pressure as well as collision. The propagation of block and ash flows can be simulated to

Kamchatka is part of a Pacific ring of volcanoes with 29 active volcanoes. These volcanoes produce explosive volcanic ash clouds every 2 or 3 years that spread across major international air routes between North America and Asia. The staff of KVERT, in collaboration with Kamchatkan Experimental and Methodical Seismological Department (KEMSD) of the Russian Academy of Sciences and the Institute of Volcanology and Seismology (IVS), monitors active volcanoes of Kamchatka seismically. This is done by visual observations and video, utilizing satellite images for ash cloud detection and tracking of thermal anomalies. As of 2003, there were 28 remote seismic stations operating at 11 of the most active volcanoes in Kamchatka and the North Kurile Islands. Three volcanoes, Bezymyanny, Sheveluch and Kyuchevskoy are being monitored by a video-camera system. Real-time images of these three volcanoes are available on the Internet, at http://emsd.iks.ru. Seismic observations are used universally to discover the start of volcano unrest and to recognize volcanic blasts of volcanoes obscured by weather. KVET examines data from U.S. and Japanese meteorological satellites, in cooperation with the Alaska Volcano Observatory. A number of times a day, images from GOES (Geostationary Operational Environmental Satellites), GMS (Geostationary Meteorological Satellite) and polar-orbiting satellites carrying AVHRR (Advanced Very High Resolution Radiometer) are examined for volcanic activity.
