Japanese satellite will monitor Russian volcanoes

The Space Research Institute of the Russian Academy of Sciences has started to use data from the Himawari-8 geostationary satellite for the monitoring system of Kamchatka and Kuril volcanoes. The scientists managed, thanks to the spacecraft, to observe a rare phenomenon of simultaneous eruption of three volcanoes of the so-called Northern Group in Kamchatka, the website of the institute informs.

On June 14−18, 2017, during the preliminary processing of the data of the Japanese satellite, the researchers of the Russian Academy of Sciences were lucky to observe a unique phenomenon ― the eruption process of three volcanoes of the Northern Kamchatka group: Shiveluch, Klyuchevsky, and Nameless. Thanks to the information provided by Himawari-8, it was possible to reconstruct the development of all the events that had taken place in the area, from the beginning of explosions (that is, the explosions related to eruptions) to the size of ash clouds and the direction of their movement. An animation, that was created based on the data, clearly illustrates the transience of powerful explosive eruptions and the long-term persistance of ash clouds in the atmosphere, which poses a real danger for civil and military aviation.

The geostationary orbit allows the satellite to «hover» over a particular point on the surface, being constantly above it. So, thanks to Himawari-8, information on the situation in territory of Kamchatka and the Kurils can be updated every 10 minutes, and every 2.5 minutes in some cases.
