ACTIVE VOLCANOES OF KAMCHATKA: SPATIAL AND TEMPORAL DYNAMICS OF ERUPTIVE INTENSITY AND PRODUCTIVITY

Abstract

The total volumes of volcanic rocks and average annual productivities of active volcanoes were calculated for all volcanic zones of Kamchatka for the mid-Pleistocene, Late Pleistocene, and Holocene epochs. Average values were computed for heat and mass transfer. A distinct spatial trend of recent volcanism was substantiated: a growth of the intensity and productivity of volcanism in a northward direction. The temporal trend was the growth of activity in the Late Pleistocene and Holocene with a peak during the Holocene.
