The third ash emission in one day was produced by the Shiveluch volcano in Kamchatka, reports the Kamchatka Volcanic Eruption Response Group of the Institute of Volcanology and Seismology, Far Eastern Section of the Russian Academy of Sciences.
“The Shiveluch volcano in Kamchatka spewed ash for the third time in 24 hours at (a height of) 8.5 kilometers above sea level. The ash column extended 120 kilometers east of the volcano.” – say the experts.
On the afternoon of November 7, an ash emission occurred in Shiveluch, 11 kilometers above sea level. According to volcanologists, the event was recorded in the area of the new dome named after the 300th anniversary of the Russian Academy of Sciences. In addition to the ash column, a pyroclastic flow composed of hot gases, slag and ash descended on the giant.
“A powerful explosive event occurred in the area of the new lava dome named after the 300th anniversary of the Russian Academy of Sciences, which is located next to the old Karan dome. Satellite images show hot pyroclastic deposits that formed as a result of this eruption. The flow of hot sediments is clearly visible on the western slope of the volcano. The length of the stream is 11 kilometers.” – says a statement from the Institute of Volcanology.
The Kamchatka branch of the Unified Geophysical Service of the Russian Academy of Sciences summarizes in its telegram channel that this eruption is not typical for Shiveluch and that the volcano has become even more dangerous.
“Prior to this event, seismicity was at background levels and a weak thermal anomaly and steam and gas activity were observed at the volcano. Previously, such events were not typical for Shiveluch; Preparation for an eruption was usually clearly reflected in seismic signals. It seems that after the last strong eruption and the opening of a new eruptive center, changes occurred in the volcano’s regime. Now we must take this situation into account. Shiveluch has become even more dangerous.” — RIA Novosti quotes the message.
