December 08, 2012 – WORLDWIDE VOLCANOES – The following constitutes the new activity, unrest and ongoing report from geologist Richard Wilson who specializes in volcano seismicity and Armand Vervaeck.
KVERT reports that eruption of basaltic andesite continues at Plosky Tolbachik (Kamchatka Peninsula). Vents have indeed localized along the eruptive fissure and cinder cones are being constructed by more explosive strombolian activity there. A MODIS satellite image shows the location of the vents in respect to the main Tolbachik edifice and also shows the relatively weak, low level eruptive plume associated with the activity. Most of the SO2 liberated by this eruption remains in the troposphere and is not being raised in any appreciable amounts into the stratosphere (greater than 20,000 ft asl at this latitude).
