Tree-Rings, Cosmic Radiation and Resolving an Ancient Volcanic Controversy


This talk will introduce a long-running scientific debate over the date of a volcanic eruption which took place more than 3,000 years ago in the Ancient Mediterranean. We’ll discuss the scientific process and what happens when different lines of evidence do not agree. We will learn why dating the Minoan eruption of Thera is so important and how University of Arizona researchers are shedding new light to resolve this long-running debate. Presented by Charlotte Pearson, Assistant Professor, UA Laboratory of Tree-Ring Research.
