Fossilized tree and ice cores help date huge volcanic eruption 1,000 years ago to within three months
An international team of researchers has managed to pinpoint, to within three months, a medieval volcanic eruption in east Asia the precise date of which has puzzled historians for decades. They have also shown that the so-called "Millennium eruption" of Changbaishan volcano, one of the largest in history, cannot have brought about the downfall of an important 10th century kingdom, as was previously thought.
Writing in the journal Quaternary Science Reviews the team describes how new analysis of the partly fossilised remains of a tree killed by the eruption, and ice cores drilled in Greenland, lead them to conclude the eruption occurred in the final months of 946 AD.
