Kizimen volcano located on the Kamchatka Peninsula Russia has got a burst of activity during the last 24 hours (August 20/21 2011). KVERT Russian scientists have measured more than 900 seismic tremors over the last 24 hours.
Earthquake-Report.com was auto-alerted by a shallow 4.3 earthquake probably caused by activity below the volcano. The tremor itself could not generate any damage as they are too weak.
The SO2 satellite date from August 21 shows activity on the same place, but the image is not strong enough to show on this page.
The volcano is in an active state since December 2010.
Kizimen volcano is located at approx. 365 km from the regional capital Petropavlovsk-Kamtchatski.
The current aviation code for Kizimen Volcano is Orange.
Kizimen volcano is located in a very remote area in Kamchatka with almost no other people than scientists living from time to time near the volcano. Weather in the area is mostly cloudy so that visual inspection of the eruption is only possible on the rare clear days.
Russian scientists are only communicating from time to time in the open Internet space (a couple of times per week)
This is what KVERT, Russian Kamchatka volcano scientific service, wrote on August 19 (this is the latest report we found from them):
Eruption of the volcano continues. Strong ash explosions up to 32,800 ft (10 km) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.
Seismic activity was above background levels all week. Weak volcanic tremor continues to registering all week. According to video data, moderate fumarole activity was observing on August 14; sometimes a gas-steam plume rose up to 9,840 ft (3.0 km) ASL. The lava flows continues to moving on the eastern flank of the volcano. A big bright thermal anomaly was registering over the volcano all week at satellite images. Gas-steam plume extending about 35.4 mi (57 km) to the north-north-east from the volcano was noted on August 15, on satellite images.
Kizimen volcano Information :
Kizimen is an isolated, conical stratovolcano that is morphologically similar to Mount St. Helens prior to its 1980 eruption. The summit of Kizimen consists of overlapping lava domes, and blocky lava flows descend the flanks of the volcano, which is the westernmost of a volcanic chain north of Kronotsky volcano. The 2376-m-high Kizimen was formed during four eruptive cycles beginning about 12,000 years ago and lasting 2000-3500 years. The largest eruptions took place about 10,000 and 8300-8400 years ago, and three periods of long-term lava dome growth have occurred. The latest eruptive cycle began about 3000 years ago with a large explosion and was followed by lava dome growth lasting intermittently about 1000 years. An explosive eruption about 1100 years ago produced a lateral blast and created a 1.0 x 0.7 km wide crater breached to the NE, inside which a small lava dome (the fourth at Kizimen) has grown. Prior to 2010, only a single explosive eruption, during 1927-28, had been recorded in historical time.
The video below was uploaded on YouTube on July 21 2011 by Russian TV. It gives an impression of the power of Kizimens eruptions.
The video below has been uploaded on February 26 2011 and shows a visit of Russian scientists by helicopter to the Kizimen volcano. They are of course taking pictures, video and snow samples from the snow covered with eruption ash.
