A team of researchers had used a method that involves the measurement of age rings from trees that grew during the East Mediterranean Bronze-Iron to identify the period when the eruption of Thera (the old name of the Santorini volcano) took place. It appears that the harrowing event occurred around 1560 BC.
During the study, the researchers performed a chemical analysis if the three-ring sequences, spotting a major chemical change which took place in the growth environment. This change took place in 1560 BC, and it is theorized that it may be associated with the eruption of the volcano.
X-ray fluorescence was employed to observe tree-ring sequences, which ranged from 1630 to 1560 BC. An unusual calcium anomy was observed around 1560, and it has been deemed to be a potential marker. The samples of Juniperus excels, which were by the scientists, were collected from the Midas Mound Tumulus and Kizlarkaya.
Last Santorini Volcanic Eruption Took Place In 1,560 BC
Calendar-dated tree-ring sequences have been used in the past to establish timelines for other notable events. Also known under the name of Minoan eruption, the Santorini eruption was one of the most powerful ones that took place on Earth, reaching a Volcanic Explosivity Index value of up to 7 points. The sheer magnitude of the event destroyed a significant part of the island of Santorini and caused tsunamis and earthquakes that have affected nearby coastal communities.
Geological data has suggested that several violent eruptions took place hundreds of years before the catastrophically Minoan eruption. It is estimated that during the major eruption, the volcano expelled an amount of rock that was up to four times higher than the one observed during the devastating Krakatoa eruption, which took place in `1883.
The resulting ash and dust clouds contributed to climatic changes around the area. While more data is needed, the current information is an important milestone that will encourage future research.
