From: Olive shrub buried on Therasia supports a mid-16th century BCE date for the Thera eruption
Radiocarbon measurements from single years of a Mediterranean juniper tree (green) run at the same laboratory / same time as the Therasia samples, relative to IntCal2016. The offset towards older ages reflects the difference between data from a single region / single laboratory and the IntCal2016 mean. To illustrate uncertainties associated with calibration, the inner-most and bark results from stem 88-2 are shown (horizontal dotted line, grey error) intersecting with two radiocarbon plateaus in the time period. If considered to represent annual growth, band counting of sample 88-2, combined with the most likely point of intersection for the inner-most determination with intCal2016, indicates a death date towards the middle of the 16th century BCE, but clear uncertainties remain.
