The volcanoes of Kamchatka are the most active in the world. Annually, from 3 to 7 volcanoes produce eruptions, during which the explosions eject ash to 10−15 km above sea level, and ash clouds spread thousands of kilometers from volcanoes. Strenuous volcanic activity could cause ash falls in towns and settlements, destruction of forests and communications. Ash clouds and plumes pose a serious threat to the present-day jet aviation. Since 1993, the Kamchatka Volcanic Eruption Response Team (KVERT) has conducted daily monitoring of Kamchatka volcanoes to mitigate volcanic hazards to airline operations and population. Since 2014, satellite monitoring of volcanoes is carried out by KVERT scientists using the VolSatView information system that since 2016 has utilized data from Himawari-8 geostationary satellite. The system has created special tools that allow us to work with promptly received data, as well as analyze series of long-term observations. Using data from Himawari-8, as well as the tools implemented in VolSatView to work with them, enables to: significantly raise the efficient response to detection of explosive events in the region; identify the onset of eruptive events with an accuracy of 10 minutes or less; track and forecast all changes in the dynamics of volcanic activity, including the near onset of strong explosive events. The paper describes the technology features for integrating Himawari-8 data into VolSatView and the main possibilities of working with them, implemented now
in the system.

SIGMA-3D software package of structural interpretation is an effective tool for the automated three-dimensional modeling while studying magnetic anomalies created by underwater volcanoes. With the help of this software package submarine volcanoes Grigorieva, Krylatka, and Yubileiny, located in the Kurile island arc, have been studied.

The construction of digital 3D models of volcanoes is now made much easier and faster after the JPL/NASA specialists have carried out an interferometer radar survey of the Earth's surface (SRTM - Shuttle Radar Topographic Mission). Computer processing of the interferometer measurements in the SIR-C/X-SAR wavelength range (L - 23 cm, С - 5.6 cm and X - 3.1 cm) enabled high accuracy to be attained in construction of 3D topographic models, marking more data on these in the geographic coordinate system, and continuing on this basis to develop "digital layers" with data from new eruptions plotted on them, resulting in quantitative estimation of erupted volumes in real time. This method also allows one to model possible locations of new eruptive centers based on fast seismological forecasts of eruptions in addition to predicting possible routes of new lava and pyroclastic flows, mud streams and labors, and assessing the range and geologic effects of an eruption, and its ecologic impact
