Abstract

Using the charcoal ash in the Kuandu well of the Taipei Basin sediments as dating material, we obtain an AMS radiocarbon result with a 14C age of 16950 + - 150 yrBP (calendar age of 19814 - 20431 yrBP). Regarding the charcoal ash as a likely remnant of a forest fire caused by volcanic eruptions, this result confirms our earlier report that there was a volcanic event around 20 Ka in the Tatun Volcano Group.
