Minoan eruption of the radiocarbon-indicated date of the eruption, there is evidence for a significant climatic event in the Northern Hemisphere like failure of crops in China (see below) and evidence from tree rings, cited above: bristlecone pines of California; bog oaks of Ireland, England, and Germany; and other trees in Sweden. The tree rings date the event to 1628 (±65 years) BCE. The eruption devastated the nearby Minoan settlement at Akrotiri on Santorini, which was entombed in a layer of pumice.
