On the territory of the Russian Far East, there are dozens of active volcanoes, requiring continuous attention of scientists for analysis and control of their condition. To provide solutions of various scientific problems, different information systems were implemented. However, disunity of information systems and limited data exchange between them limit the possibility of carrying out complex studies. This may result in disastrous consequences for the population and different fields of people's activities. The article describes the developed service-oriented software interface that implements interaction between the main existing information systems. The mutual use of accumulated sets of scientific data and processing instruments improves research and operational monitoring of the state of volcanoes in Kamchatka and Northern Kuriles.

The article presents data on two explosive eruptions produced by Ebeko Volcano 19 to 20 October, 2016 and over the period from November 8, 2016 till the end of August 2017. The latter eruption continues. The material was erupted from three vents: one vent is located in the Active funnel and two vents are at the bottom of Middle crater. The authors analyzed the chemical, mineral, and granulometric compositions of tephra. The studied tephra does not contain magmatic components. The authors classify the eruptions as phreatic. The paper provides the assessment of the composition and volume of gas emission. The gross total volume of the erupted material was estimated to exceed 1.5 million tons.

With the use of the method of low-frequency microseismic sounding, the configuration of the magmatic feeding system of the Tolbachinsky Dol—a regional zone of areal basaltic volcanism in the southern part of the Klyuchevskoy volcano group in Kamchatka—is studied. The initial data are obtained by a step-by-step recording of the background microseismic noise in 2010–2015 within a thoroughly marked-out survey area covering the zones of fissure eruptions in 1975–1976 and 2012–2013 and, partly, the edifice of thePloskii (flat) Tolbachik volcano. The depth sections ref lecting the distributions of the relative velocities of seismic waves in the Earth’s crust are constructed. For a more reliable interpretation of the revealed deep anomalies, the results of independent geological and geophysical studies are used. The ascertained low-velocity structures are closely correlated to the manifestations of present-day volcanism. It is shown that the feeding structure of the Tolbachinsky Dol is spatially heterogeneous, incorporating subvertical and lateral pipe-shaped magma conduits, closely spaced magma feeding channels, and shallow magma reservoirs. A long-lived local transcrustal magma conducting zone is revealed, and regularities in the deep structure of the feeding systems of fissure eruptions are identified. The configuration of the established subvertical magma conduits permits basalts moving to rise to the surface by different paths, which, inter alia, explains the contrasting magma compositions observed during a single eruption. Thus, based on the instrumental data, it is shown that the magmatic feeding structure of the Tolbachinsky Dol has a number of specific peculiarities and is significantly more complicated than has been previously thought about the areal volcanic fields.

The paper shows that the abnormally low values of longitudinal wave velocities, typical even for dense differences, are an important feature of Holocene effusive rocks of medium-basic composition. In order to explain this phenomenon, a series of experiments was conducted to saturate the samples with a phosphor followed by a study of the structure of the pore-fractured space on a fluorescent microscope. The experiments showed that low P-wave velocities are caused by the network of the finest microcracks formed in the rock during cooling and crystallization of the magmatic melt.

The paper presents data on identified and described short-term local (1955−1976) enhanced volcanic activity within the Northern Group at the Central Kamchatka Depression and regional disasters (1907-1976), clearly revealed within Kamchatka Peninsular and the Kurile Islands. In scale (volume is about 9 km3, weight of erupted and replaced productswas calculated to be about 16×109 t), the local volcanic disaster was the most powerful in Kamchatka and Kurile Islands over the period of the last 2000 years. This volume exceeds 80% of ~19×109 t totally erupted by all volcanoes over the same period of time. Over the period 1907−1976, the Kamchatka and Kurile volcanoes erupted and transported about 29.5×109 t of juvenile and resurgent material while other volcanoes in the world erupted about 122×109 t.

Here we present the results of the successful application of VIIRS satellite data for monitoring and reconstruction of the eruption history of Snow volcano (Chirpoi Island, Kuriles) in 2012–2017. We used Nightfire algorithm to accomplish our tasks. This algorithm differs significantly from the other similar systems due to simultaneous usage of numerous diapasons of the infrared spectra (from near to long ranges) together with the data of the visible spectra, while most of the other algorithms (for example, MODVOLC and MIROVA) use one or two diapasons from the middle or long parts of the infrared spectra. Our research shows that the maximal thermal radiation power (MW) was observed from November 2012 to January 2013. During this period, first and most voluminous portion of lava flow was produced. There are four more well-distinguished periods of this eruption: September – October 2013; March – June 2014; August – November 2014; April – June 2015. All of them correspond to the impulses of the fresh lava eruptions, although the thickness of these lava flows is smaller compared to the first period.
