Klyuchevsky volcano news & activity updates

Kliuchevskoi volcano (Kamchatka), eruption update: strong strombolian activity, 2 lava flows and ash up to 9km altitude

Thursday Oct 28, 2010 06:59 AM |

Kliuchevskoi remains highly active, producing spectacular strombolian activity and two lava flows from the summit.
KVERT reports tthat over the past week, two lava flows from the summit crater traveled down the SW and W flanks. Satellite observations show a large thermal anomaly and ash plumes drifting 420 km E and SE. Strombolian activity has been ejecting fresh lava to up to 250 m above the crater, and ash plumes rising to an altitude of up to 7.5 km (24,600 ft) on 20 Oct 2010.
An increase of activity was observed on 23 October: the ash plume reached 8-9 km altitude and drifted more than 300 km north. On 24 Oct, activity decreased a bit, but increased again on 25 Oct when ash rose to 8-8.5 km and drifted SE.

Background:

Kliuchevskoi is Kamchatka's highest and most active volcano.  Since its origin about 6000 years ago, the beautifully symmetrical, 4835-m-high basaltic stratovolcano has produced frequent moderate-volume explosive and effusive eruptions without major periods of inactivity.  Kliuchevskoi rises above a saddle NE of sharp-peaked Kamen volcano and lies SE of the broad Ushkovsky massif.  More than 100 flank eruptions have occurred at Kliuchevskoi during the past roughly 3000 years, with most lateral craters and cones occurring along radial fissures between the unconfined NE-to-SE flanks of the conical volcano between 500 m and 3600 m elevation.  The morphology of its 700-m-wide summit crater has been frequently modified by historical eruptions, which have been recorded since the late-17th century.  Historical eruptions have originated primarily from the summit crater, but have also included numerous major explosive and effusive eruptions from flank craters.
