The Minoan eruption was a major catastrophic volcanic eruption that devastated the Aegean island of Thera now called Santorini in around BCE. Although there are no clear ancient records of the eruption, the Minoan eruption may have been alluded to in the Egyptian Tempest Stele ,  as well as the Chinese Bamboo Annals. Geological evidence shows the Thera volcano erupted numerous times over several hundred thousand years before the Minoan eruption. In a repeating process, the volcano would violently erupt, then eventually collapse into a roughly circular seawater-filled caldera , with numerous small islands forming the circle. The caldera would slowly refill with magma, building a new volcano, which erupted and then collapsed in an ongoing cyclical process.
Aug 16, Thousands of years ago, on what is now the Greek island of Santorini, a mountain exploded in one of the largest volcanic eruptions in recorded history. But scientists have had difficulty establishing exactly when the Minoan volcano Thera erupted - until now. Santorini Eruption Radiocarbon Dated to B.C. by Walter L. Friedrich, Bernd Kromer, Michael Friedrich, Jan Heinemeier, Tom Pfeiffer, and Sahra Talamo Science, 28 April Abstract Full Text Supporting Online Material. Radiocarbon dating gave the tree's date of death (and therefore the date of the eruption) as BCE at 95confidence levels, which matches very neatly with the dates from Manning's study.
A similar event might have been the final trigger for the catastrophic landslide that let the cone collapse and cause a devastating tsunami on 22 Dec Why is there advertising on this site?

The island of Santorini is the result of a complex history of volcanic eruptions over about 2 million years, during which the island has changed its shape and size repeatedly. Before any volcanic activity took place caused by the subduction of the African plate under the Eurasian onethere was a small island in the area, similar to the other Islands of the Cyclades. This non-volcanic island forms the Profitis Ilias and Mesa Vouno mountains, as well as the shists at Athinios harbour and in the Plaka bay connected to Profitis Ilias mountain through the ridge of Pirgos, the Gavrilos ridge the "windmill hill" south of Emborio and the islolated rick of Monolithos.
Volcanism in the area of Santorini started about 2 million years ago when the first eruptions occurred from the sea floor in the area of the Akrotiri Peninsula and probably also at the location of the Christiania Islands 20 km SW of Santorini. The activity built dacitic lava domes that eventually formed a series of islands, still visible in the hills of the Akrotiri peninsula.
In a second stage, a stratovolcano Peristeria volcano was formed in the northern part of Santorini, parts of which are still visible in the cliffs and slopes of Mikro Profitis Ilias and Megalo Vouno.

The caldera cliffs near the site looking north; the Minoan deposit is the thick topmost layer including a 5 m thick base of fall-out pumice.
Construction is consuming the pumice layer from top down, and destroying important geological features visible in the wall. The caldera cliffs near the site looking south.
The first photo of the site: holes in the basal pumice layer, here about 5 meters thick, where the branches of the tree were. The "Science" branch was from the large hole. A piece of wood is lying on the ground Other holes left of the one where the "Science" branch was from; they have been covered now in by continuing careless building activity.
('Bronze Age catastrophe and modern controversy: dating the Santorini eruption', March ). Here, the authors respond to those recent contributions, citing evidence that closes the gap between the conclusions offered by previous typological, stratigraphic and radiometric dating techniques. Aug 17, Why then does archaeological dating usually place the Minoan Santorini eruption in the 18th Dynasty around BCE, whilst radiocarbon dating of the volcanic event at Akrotiri (Thera) yielded a calibrated age of - cal BCE, a difference of more than a century? Jan 02, Abstract The date of the volcanic eruption of Santorini that caused extensive damage toMinoan Crete has been controversial since the s. Some have placed the event in the late seventeenth century BC. Others have made the case for a younger date of around thatliz.com by:
Near the site is a man-made structure resembling a wall or well; perhaps the spot had a particular significance due to the presence of rare trees, as today, years ago. Two large, connected holes at the base of the pumce.
Deep inside one of them, one could barely see wood, too. This piece was first recovered in July and brought a wonderful, almost 2 meter long branch back to light, which is now displayed in the new geological museum in Perissa. The cross section of the branch visible in the large hole at about 2 meters height in the wall; this is the piece that was first recovered and subject of the published investigation.

Walter Friedrich at the site Feb. Debris of loose deposit is being dumped from the construction site in 20 meter above the site. The first hole where the "Science" branch was recovered is now accessible by foot and will soon be covered. View inside the hole, were the continuation of the original branch is still visible now recovered and destined for the museum in Perissa.
Organic remnants of olive leaves in the basal layer of the pumice, proof that the tree was alive at the time of the eruption. The site and the second branch. Sample of ash with olive leaves. The second piece of wood from the same hole after its recovery.
Numerous pottery fragments are found in the Minoan soil near the site. Walter Friedrich on his way from the site.

Speaking, santorini eruption dating very pity
Two hundred of the samples came from long-lived bristlecone pines that were growing in California and Nevada during the specified timeframe. The remaining 85 were from Irish oak trees from the same time. Both of these types of trees are excellent sources for studying the past, because they lay down a single ring every year.
Aug 09, To be fair, the carbon dating of the Santorini eruption does not rely on that one olive branch alone. Research groups such as Manning's have dated . Eruptions of Santorini since the Bronze Age: BC +-7 years (the so-called "Minoan eruption") Historic eruptions: BC (Palea Kameni) 46/47 AD (Palea Kameni? Bankos Reef?) AD (Palea Kameni) (perhaps only one year of the interval, Mikri Kameni, now part of Nea Kameni) (formation of Nea Kameni) (Nea Kameni) (Nea Kameni) (Nea . Apr 21, Access to this article can also be purchased. The Greek island of Santorini (named Thera in ancient times) is located in the Aegean Sea and experienced a massive volcanic eruption some 3, y ago (? BCE). Recent geological investigations have concluded that the eruption was even more massive than originally thought (1).Cited by: 1.
The radiocarbon in those individual rings decays at a steady rate, which means - based on a the current radiocarbon calibration curve that's been developed over the last 50 years - a dendrochronologist can accurately date each ring. Thera's eruption was massive.
It buried the Minoan settlement of Akrotiri under a layer of ash and pumice over 40 metres feet deep.
