There are 36 active volcanoes in Kamchatka and Northern Kuriles, from 3 to 8 volcano eruptions occur here every year. Daily satellite monitoring of volcanoes has been performed by the Kamchatka Volcanic Eruption Response Team (KVERT) since 1997 in cooperation with colleagues from the Alaska Volcano Observatory (USA). Since 2002, KVERT scientists have processing and analyzing primary images of satellite systems NOAA (AVHRR), TERRA and AQUA (MODIS), etc. in close–to–real time to detect ash plumes and thermal anomalies on active volcanoes. The multiparameter analysis of the available published information about volcanoes, as well as visual and satellite data obtained by KVERT scientists during 24 years of daily monitoring of volcanic activity, made it possible to identify the main features of the activity at each of the active volcanoes and assess their degree of danger for air transportation and population of the peninsula. With the creation in 2011 of the information system “Remote monitoring activity of volcanoes of Kamchatka and the Kuriles (VolSatView)”, volcanologists opportunity have the opportunities that have no analogues in the world to conduct satellite observations of active volcanoes. VolSatView combines a wide range of data from various satellite systems coming from different sources and allows us to process operational and retrospective satellite information directly in the web–interface by means of specially created tools, to compare it with video information, to simulate ash plumes propagation, to classify various volcanogenic objects and etc. VolSatView enables to solve problems at different levels — from on–line monitoring of volcanoes activity to the fundamental problems in volcanology. The character of volcanic activity changes and the actuality of solving the problem of “how the volcano works” remain. To accomplish this task and for searching precursors of explosive volcanic eruptions, it is necessary to continue long–term remote observations of the volcanoes in the region; to study changes in their activity with time; to compare behavior of volcanoes supplying the eruptive products of similar and contrast compositions to the earth surface.

An explosive eruption of Young Shiveluch Volcano occurred on September 22, 2005, discharging a pyroclastic flow about 20 km long in the Baidarnaya River valley and an ashfall in the area of the Northern cluster of volcanoes.

Volcano Young Sheveluch is one of the most active volcanoes in Kamchatka. Since August 1980 to the present time, an extrusive dome has been growing in the crater of the volcano. Plastic lavas in the form of large ribbons were noted on the dome already in 1980–1981, the first lava flow was observed after a paroxysmal eruption on May 9, 2004. The next large block of lava started to extrude in the end of April – beginning of May 2020. By June, 11th, it rose above the dome on 50–80 m, and up to 120 m by the end of October. On September 28, it was noted that the lava block acquired smooth surfaces. Portions of lava squeezed out from inside of the volcano in August – September were plastic. By December 8, the block had collapsed. In February 2021, a new block of plastic lava began to rise from the destroyed block. In March its height above the dome exceeded 50–60 m, and 200 m in June.
