The results of near real-time monitoring of the active Kamchatka volcanoes are described. Continuous monitoring was carried out using three remote methods: 1) seismic monitoring according to automatic telemetric seismic stations; 2) visual and video observation; 3) satellite observation of the thermal anomalies and the ash clouds. Daily information about volcanic activity is published in the Internet (http://www.emsd.ru/~ssl/ monitoring/main.htm) since February 2000. Annual results of seismic activity of the Northern (Shiveluch, Klu-chevskoy, Bezymianny, Krestovsky and Ushkovsky), Avacha (Avachinsky and Koryaksky), Mutnovsky-Gorely volcano group and Kizimen volcano are presented. 4983 earthquakes with КS=2.1–8.7 were located for Northern volcano group, 469 earthquakes with КS=1.6–6.1 – for Avacha volcano group, 459 earthquakes with КS=1.9–6.1 – Mutnovsky-Gorely volcano group, 220 earthquakes with КS=2.4–8.5 for Kizimen volcano and 238 earthquakes with КS=2.5–8.4 for Zhupanovsky volcano in 2014. Maps of epicenters, quantities of seismic energy and earth-quake distribution according to class are given. All periods of activity were fixed and investigated by remote me-thods in 2014: intensive volcanic activity of Shiveluch volcano associated with new cone, a con-tinuation of the seismic and volcanic activity of Zhupanovsky volcano after 56-year quite period and the ending of the summit explosive-effusive eruption of Kluchevskoy volcano in January-February.

Аннотация. Приведены результаты мониторинга активности действующих вулканов Камчатки по данным следующих наблюдений: 1) непрерывное слежение за сейсмичностью вулканов по данным радиотелеметрических сейсмических станций в режиме, близком к реальному времени; 2) визуальные и видеонаблюдения; 3) контроль термальных аномалий и пепловых выбросов по спутниковым данным. Информация об активности вулканов с февраля 2000 г. доступна в Интернете по адресу: http://www.emsd.ru/~ssl/monitoring/main.htm. Дан анализ сейсмической активности в районах Северной (Шивелуч, Ключевской, Безымянный, Плоский Толбачик, Ушковский и Крестовский), Авачинской (Авачинский и Корякский), Мутновско-Гореловской (Мутновский и Горелый) групп вулканов и вулканов Кизимен и Жупановский за год. В 2013 г. в районе Северной группы локализовано 4390 землетрясений с К S =3.0-8.5, Авачинской-213 с К S =1.8-5.7, Мутновско-Гореловской-110 с К S =2.7-7.2, 199 землетрясений с К S =3.0-8.5 вблизи влк. Кизимен и 22 с К S =3.7-6.7-влк. Жупановский. Приведены карты эпицентров, дано распределение землетрясений по энергетическим классам, рассчитано общее количество выделившейся сейсмической энергии. По данным всех видов наблюдений зафиксированы и детально прослежены все периоды активизаций вулканов в 2013 г.: интенсивная вулканическая деятельность влк. Шивелуч, связанная с ростом нового купола, субплинианское вершинное извержение влк. Ключевской, сейсмическая и вулканическая активизация влк. Жупановский после 56-летнего периода покоя, а также завершение мощных продолжительных извержений вулканов Плоский Толбачик и Кизимен. Ключевые слова: сейсмическая активность действующих вулканов, визуальные и видеонаблюдения, энергетический класс К S , сейсмическая энергия, график повторяемости землетрясений.

Continuous monitoring was carried out using three remote methods: 1) seismic monitoring according to automatic telemetric seismic stations; 2) visual and video observation; 3) satellite observation of the thermal anomalies and the ash clouds. Annual results of seismic activity of the Northern (Shiveluch, Kluchevskoy, Bezymianny, Krestovsky, and Ushkovsky), the Avacha (Avachinsky, and Koryaksky), the Mutnovsky-Gorely volcano groups and the Kizimen volcano are presented. 5464 earthquakes with КS=1.8–8.1 were located for the Northern volcano group, 302 earthquakes with КS=1.7–5.7 – for the Avacha volcano group, 295 earthquakes with КS=2.1–6.8 for the Mutnovsky-Gorely volcano group, 462 earthquakes with КS=2.2–8.3 for Kizimen volcano, and 165 earthquakes with КS=2.5–8.4 for Zhupanovsky volcano in 2015. Maps of epicenters, quantities of seismic energy and earthquake distribution by energy classes are given. All periods of activity were fixed and investigated by remote methods in 2015: intensive volcanic activity of the Sheveluch volcano associated with a new cone; the summit explosive-effusive eruption of the Kluchevskoy volcano in January–April; and a continuation of seismic and volcanic activity of the Zhupanovsky volcano after 56-year quite period.

The results of seismic activity of the Northern (Shiveluch, Kluchevskoy, Bezymianny, Krestovsky and Ushkovsky), Avacha (Avachinsky and Koryaksky), Mutnovsky-Gorely volcano group and Kizimen volcano for 2016–2017 are presented. Within two years 8152 earthquakes with KS=1.6–8.5 were located for Northern volcano group, 616 earthquakes with KS=1.6–7.2 – for Avacha volcano group, 357 earthquakes with KS=2.0–6.2 – Mutnovsky-Gorely volcano group, 144 earthquakes with KS=2.3–9.4 for Kizimen volcano, 322 earthquakes with KS=1.8–8.1 for Zhupanovsky volcano and 90 earthquakes with KS=5.0–8.6 for Kambalny volcano. Maps of epicenters, quantities of seismic energy and earthquake distribution according to class are given. All periods of activity were fixed and investigated by remote methods in 2016–2017: intensive volcanic activity of Sheveluch volcano associated with new cone, the summit explosive-effusive eruption of Kluchevskoy volcano from April 2016 till September 2017, explosive activity of Zhupanovsky volcano and seismic preparation and volcanic eruption of Kambalny volcano observed for the first time in historical period.
