    More than 3, years ago a catastrophic volcanic eruption struck ancient Thera, known today as the Greek island of Santorini. Ash and pumice rained across the Mediterranean, and tsunami waves rolled onto faraway shores in Crete. In the s archaeologists on Santorini uncovered a Minoan settlement frozen in time, with vibrant wall frescoes decorating multistory houses, all buried by volcanic debris. The eruption was one of the most powerful volcanic explosions of the past 10, years and a crucial time point of the Mediterranean Bronze Age.

Researchers use data from tree rings, sediment layers and other samples to calibrate the process of carbon dating. Radiocarbon dating — a key tool used for determining the age of prehistoric samples — is about to get a major update. For the first time in seven years, the technique is due to be recalibrated using a slew of new data from around the world.

    Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material. But new research shows that commonly accepted radiocarbon dating standards can miss the mark -- calling into question historical timelines. Archaeologist Sturt Manning and colleagues have revealed variations in the radiocarbon cycle at certain periods of time, affecting frequently cited standards used in archaeological and historical research relevant to the southern Levant region, which includes Israel, southern Jordan and Egypt. These variations, or offsets, of up to 20 years in the calibration of precise radiocarbon dating could be related to climatic conditions. Pre-modern radiocarbon chronologies rely on standardized Northern and Southern Hemisphere calibration curves to obtain calendar dates from organic material.
