The pronounced change in the Shiveluch magma compositions could have been related to adjustments of the magma plumbing system beneath Old Shiveluch following the large scale sector collapse in the Late Pleistocene that enabled a common mixing of evolved and primitive magmas on the later, Holocene stage of the volcano evolution.
Oktyabr’skaya Spit is a polygenetic aggradational landform, about 35 km long. It borders the Bol’shaya river estuary (south-western coast of Kamchatka) from the sea of Okhotsk. This talk is based on literature and archival data (18th–20th century) and on fieldwork (2005, 2010–2012 years). Secular, long-term and seasonal dynamics of Oktyabr’skaya Spit is discussed.
Extreme storm events occur on Oktyabr’skaya spit (Kamchatka) every year and destroy the only road connecting Oktyabr’skii village with the mainland. 30.11.2011 and 2.04.2012 we had a unique possibility to be on the spit at
the time of such events. Significant geomorphic change occurred and the road was damaged. We documented the processes, as well as the effects.
