    Abstract

    Tephra from the Cape Riva (Y-2) eruption of Santorini has been found across the eastern Mediterranean. It presentsan important link between marine and terrestrial records. A Poisson process (P Sequence) age-depth prior, with model averaging, is used to model individual previously published radiocarbon sequences, cross-linked with an exponential phase model parameter to obtain a robust age. Multiple sequences and 14C determinations from 3 eastern Mediterranean data sets(Seymour et al. 2004; Margari et al. 2009; Müller et al. 2011; Roeser et al. 2012) are used in the model. The modeled age ofthe Y-2 tephra produced within this study is 22,329–21,088 cal BP at 95.4% probability.
