AMS (super 14) C dating of historic eruptions of the Kirishima, Sakurajima and Kaimondake volcanoes, southern Kyushu, Japan.

Mitsuru Okuno, Toshio Nakamura, Tetsuo Kobayashi

Abstract


In the historic period, several large eruptions were recorded from Kirishima, Sakurajima and Kaimondake volcanoes in southern Kyushu, Japan. Estimated dates of volcanic activity were established on these volcanoes through historical documentation of major eruption events. This study presents the correspondence between these documents and the records of AMS (super 14) C dating of soils underlying tephra layers. We conclude that AMS (super 14) C dates of soil materials can be useful in correlating tephra layers with documentary records of eruption.
