A large explosive eruption of Young Shiveluch Volcano took place on February 27,2005. The event gave rise to an eruption cloud depositing ash over an area of about 25000 km2 in Kamchatka, part of the ash falling in the Sea of Okhotsk: a pyroclastic flow was extending in five branches for 25 km from the volcanic dome, minor mud flows were recorded. The Novyi lava dome decreased in height by about 130 m.

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.

Созданная в 2010 г. совместными усилиями специалистов ИВиС ДВО РАН, ИКИ РАН, ВЦ ДВО РАН и ДЦ ФГУП НИЦ Планета информационная система «Мониторинг активности вулканов Камчатки и Курил» (VolSatView, http://volcanoes.smislab.ru), продолжает развиваться и сегодня позволяет работать с различными спутниковыми данными среднего и высокого разрешения, метео- и инструментальной информацией наземных сетей наблюдений, проводить совместный анализ различных данных.
