“Reports from Russia indicate that a large eruption of Shiveluch began yesterday. A bulletin from the Kamchatka Volcanoes Emergency Response Team (KVERT), issued at 22:35 UTC on 10 September warns that ‘Ash explosions > 10 km (>32,800 ft) ASL from the volcano could affect international and low-flying aircraft’. According to the bulletin, ‘strong explosions’ occurred between around 14:19 and 14:55 UTC on 10 September, with seismic data indicating ash plumes reaching 15000 metres above sea level; if ash plumes are indeed reaching 10-15 km altitude, then this is a sizeable event. The bulletin reports that according to seismic data ‘10 volcanic events (ash explosions and hot avalanches or pyroclastic flows) occurred at the lava dome from 16:33 till 20:25 UTC on September 10′. Whether the activity is still continuing is not clear, and there are no visual or satellite images of this event because of cloud cover.”
På KVERT:s hemsida (KVERT står för Kamchatkan Volcanic Eruption Response Team) informeras vi om följande:
“Activity of the volcano continues: a new viscous lava flow effuses at the lava dome. Ash explosions > 10 km (> 32,800 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.”
KVERT har dock ändrat flygkoden från Röd till Orange.
