One of the largest volcanic eruptions in the past 4, years burst from the volcano Thera on what is now the Greek island of Santorini. The Cornell-led team questioned those assumptions: Applying their results to previously published chronologies, the researchers show how even the relatively small offsets they observe can shift calendar dates by enough to alter ongoing archaeological, historical, and paleoclimate debates.
Pearson explained in an email to The Times of Israel that her team attempted to create an annual average plateau from the C records gleaned from individual securely dated tree-rings, such as Irish oak trees and the North American bristlecone pine. The ancient Minoan town of Akrotiri on Santorini was damaged by earthquakes before the eruption, then buried under ash.

An article published in May by the IAC researcher Hector Socas proposed a new technomarker, characterized by the fact that it could be produced by present day technology on Earth. The curve is based on securely dated findings taken from trees, usually oaks or conifers, from the northern hemisphere.
