Minoan eruption in the context of "Year Without a Summer"

Santorini, officially Thira or Thera, is a Greek island in the southern Aegean Sea, about 200 km (120 mi) southeast from the mainland. It is the largest island of a small, circular archipelago formed by the Santorini caldera. It is the southernmost member of the Cyclades group of islands, with an area of approximately 73 km (28 sq mi) and a 2021 census population of 15,480. The municipality of Santorini includes the inhabited islands of Santorini and Therasia, and the uninhabited islands of Nea Kameni, Palaia Kameni, Aspronisi, Anydros, and Christiana. The total land area is 91 km (35 sq mi). Santorini is part of the Thira regional unit.

Santorini is the most active volcanic centre in the South Aegean Volcanic Arc. The volcanic arc is approximately 500 km (300 mi) long and 20 to 40 km (12 to 25 mi) wide. The region first became volcanically active around 3–4 million years ago, though volcanism on Thera began around 2 million years ago with the extrusion of dacitic lavas from vents around Akrotiri. One of the largest volcanic eruptions in recorded history struck the island about 3,600 years ago, leaving a large water-filled caldera surrounded by deep volcanic ash deposits.

Aspronisi (Greek: Ασπρονήσι) is an uninhabited island lying within the Santorini caldera. The island was originally formed by the massive Minoan eruption in the 2nd millennium BC, after which it was gradually built up by successive volcanic activity. The name Aspronisi, which means 'White Island' in Greek, is derived from the island being partially composed of white pumice.

Akrotiri (Greek: Ακρωτήρι, pronounced Greek: [akroˈtiri]) is a Cycladic Bronze Age settlement site on the volcanic Greek island of Santorini. The name comes from the nearby village of Akrotiri.

The settlement was destroyed during the Theran eruption sometime in the 16th century BC, and was buried in volcanic ash, which helped preserve its fine frescoes. Akrotiri has been excavated since 1967, after earlier excavations on the island.

Minoan chronology is a framework of dates used to divide the history of the Minoan civilization. Two systems of relative chronology are used for the Minoans. One is based on sequences of pottery styles, while the other is based on the architectural phases of the Minoan palaces. These systems are often used alongside one another.

Establishing an absolute chronology has proved difficult, since different methodologies provide different results. For instance, while carbon dating places the eruption of Thera around 1600 BC, synchronism with Egyptian records would place it roughly a century later.

Spyridon Marinatos (Greek: Σπυρίδων Μαρινάτος; 17 November [O.S. 4 November] 1901 – 1 October 1974) was a Greek archaeologist who specialised in the Minoan and Mycenaean civilizations of the Aegean Bronze Age. He is best known for the excavation of the Minoan site of Akrotiri on Thera, which he conducted between 1967 and 1974. He received many honours in Greece and abroad, and was considered one of the most important Greek archaeologists of his day.

A native of Kephallonia, Marinatos was educated at the University of Athens, the Friedrich Wilhelms University of Berlin, and the University of Halle. His early teachers included noted archaeologists such as Panagiotis Kavvadias, Christos Tsountas and Georg Karo. He joined the Greek Archaeological Service in 1919, and spent much of his early career on the island of Crete, where he excavated several Minoan sites, served as director of the Heraklion Museum, and formulated his theory that the collapse of Neopalatial Minoan society had been the result of the eruption of the volcanic island of Thera around 1600 BCE.
