According to Giardino , the problem of establishing a reliable date results from the differences of calibration - on the one hand organic samples ( such as charcoal : 1880 – 1680BC ) and on the other hand , soil faeces ( 1684 – 1535 BC ) . He prefers the earlier as the more reliable date . The Avellino Eruption separates archaeologically the Early Bronze Age in Campania from the Middle Bronze Age A study published in 1990 by Vogel and others suggested that the Avellino eruption was responsible in part for the climatic disturbances of the 1620s BC . The latter were verified by tree-ring series and ice-core layers . The authors had just obtained carbon dates of 3360 ± 40 BP , or 1617 – 1703 calibrated BC . They were suggesting a coincidence of a number of eruptions , such as the Minoan eruption on Santorini . The hypothesis remains unverifiable a generation later , due to the overall imprecision of the dates
