CATASTROPHIC LATE PLEISTOCENE AND HOLOCENE NATURAL EVENTS AND THEIR ECOLOGY RESULTS

There are some important natural catastrophic events within European part of Russia: they are landscape’s changes in the north of arid zone; desertification phenomenon; dust storms and ash falls; glacial catastrophic events during degradation stage in the north (serdges, lateral faults into glacier); hydrological events (Caspian sea level changes, lake’s level changes; flooding events within river plain); sedimentary events in the glacial shelves, in the river and lakes with formation of glacial turbidity structures, gravity stream formations, suffusion-karst phenomenon, and paleoseismicity events; critical stages of land fauna evolution. Most of these events influenced on the primitive human cultures evolution and on primitive people society migration. Recognition the rhythmic of extremely events and their duration and reasons of their origin help to made prognoses scenarios of formation and evolution these processes in the future. It is very important to account that catastrophic events are characterized by as linear and nonlinear regimes. Extremely natural events had occurred during as cold as warm period. Their influences on people’s popular distribution are demonstrated in this report. (project 3.8. DSG RAS)
