In this paper the set of radiocarbon dates obtained for the caldera-forming early-Holocene Kurile Lake eruption, which deposited a very important key-marker ash (KO) and formed the isochronous benchmark, is analyzed. Previous 12 dates derived from samples collected mostly far from caldera, and fall into the significant time interval (7890-7530 BP). In 1996-98 we performed the extensive sampling of organic matter related to pyroclastic flow and fall KO deposits, and 17 new dates were obtained. We selected the valid dates from both data sets analyzing the sample types and taphonomy, to estimate the accurate age of the KO eruption, and sharpened the time-span (7690-7530 BP) where the reliable dates fall. The estimated age is 7618š14 BP (Cal. 6455 BC).
