Background

The island group of Santorini is the most well-known and active volcanic centre of the Hellenic Volcanic Arc in the south Aegean Sea. It is a very complex stratovolcano dominated by a large, sea-flooded caldera created by several large explosive eruptions. The different products of about 2 million years of volcanic activity have accumulated around a small non-volcanic basement, that once formed a small island similar to the other cycladic islands. Most of the volcanic layers are visible in the multi-colored sequences of the impressive steep inner walls of the caldera, striking the visitor who reaches the island by boat.The last eruption took place in an phreatic eruption on Nea Kameni island in 1950.

The Minoan Eruption
Santorini's volcanic activity during the past 2-500,000 years has been dominated by very large explosive eruptions at intervals of few tens of thousands of years. The most recent of this type occurred at around 1613 BC and is known as the so-called Minoan eruption. The late Bronze Age eruption, one of the biggest known volcanic explosions in younger time,- and one of the most studied, but still most mysterious eruptions of all time-, devastated not only Santorini, but had a deep impact on the whole of the Eastern Mediterranean. Perhaps it even had serious world-wide effects and changed history.
Still today, one can see its deposits, the characteristic, tens of meters thick layer of white pumice and ash that blankets most of the surface of the island group. The eruption changed the shape of the island itself dramatically: it is now believed that before the eruption, it had the shape of an almost complete ring that enclosed an earlier, shallower caldera. Then, large sections of island collapsed into the emptied magma chamber after the eruption, literally disappearing under the sea. The ring-island was breached to the W and NW, and the caldera was significantly widened and deepened.
The Minoan eruption devastated the rich, highly developed economic center, that Santorini was at that time. Since 1969, intense archaeological excavations have brought to light an important Cycladic/Minoan town which had been buried beneath the volcanic ash for almost 4000 years. Although it appears that people had time to evacuate their island in time before the eruption, carrying most of their goods with them, the findings from Akrotiri are impressive: especially, they include well-preserved and magnificent wall paintings, ceramics and other objects. Thanks to the work of numerous archaeologists, a new light was thrown on an important prehistoric period and culture. The spectacular discovery even induced continuing speculations that relate the volcanic destruction of Santorini to the legend of the sunken Atlantis.

The historic eruptions of Santorini volcano (Palea and Nea Kameni)
Although at present dormant, Santorini has been active several times in historic time. Since its last major explosive eruption (at about 1645 BC) numerous minor and medium-sized, mainly effusive eruptions have occurred. This activity built the dark-colored islands of Nea and Palea Kameni inside the caldera. Their first appearance was witnessed and reported by Greek and Roman writers. The last eruption on Nea Kameni occurred in 1950. At present, Santorini is dormant, and volcanism manifests as fumarolic activity and hot springs around the islands.

Info

1650 AD Sep 26:
Some died of opthalmias caused by sulfurous vapor; others (approx. 50) were suffocated by vapors on Sept 30. The crew of a ship passing too near the volcano was suffocated on Oct 2. Others (approx. 20 laborers) were killed by a shower of black dust on Nov 4. Fytikas attributes 50 deaths to a tsunami, and does not mention other fatalities. [Reference #1633 - Fytikas lists 50 deaths due to gases from the eruption?] (reference #9675)
On 29/9/1650 a tsunami caused serious damage to Thera's coasts and to other islands, within a radius of 150 km. The SO₂, which was produced in large quantities from Kolombos centre, proved to be a serious danger when the volcanic plume was directed by the wind towards Thera. More than 50 people lost their lives and more than 1O00 animals were killed... Gases from the eruption of 1650 caused the death of 50 people and more than 1O00 animals on Thera. (reference #1633)

At least seventy people staying offshore or along the north-eastern coast of Santorini died from asphyxiation. Men approaching the eruption site by boat on October 2 were found burnt, but there is no clear evidence of pyroclastic surges flowing over water to reach the coast of Santorini, as occurred during the 1883 eruption of Krakatau (Carey et al.,1996; Paris et al., 2014b).

Info

46 AD:
46 AD July 6. Thera. At the same time as an eclipse of the Moon, probably following a subdued eruption, an islet, which became known as Theia, rose up from the sea between Thera and Therasia in the Cyclades.
This event is well documented by contemporary authors, including Seneca, who confirms that it happened in his own time and during the consulship of Valerius Asiaticus (AD 46). Dio Cassius dates it Roman year 800 (AD 47), while St Jerome gives the fifth year of Olympiad CCVI (AD 45), and notes the length of the island as 30 stadia (5.5 km). Orosius (writing early in the fifth century AD) dates it to the fifth year of Claudius (AD 45-46).

Since Aurelis Victor mentions that it happened on the same night as a lunar eclipse, there is a chance of dating the eruption accurately. Schove and Fletcher (1987, 9-11) derive several dates, noting that the most popular is 31 December AD 46, because this would embrace both Seneca's date of AD 46 and Dio's of AD 47. However, he thinks that 6 July AD 46 is more probable because the eclipse would have been distinctly noticeable by about 8.53 pm, and consequently more likely to be recorded.

Modern cataloguers associated this eruption with the Crete earthquake of 62-64, dating it 53/52/66. Guidoboni (1989, 661-662), Guidoboni et al. (1994, 193-194) associate this eruption at Thera with the Crete earthquake of 62-64, dating it 53/52/66 for which I have no evidence.

Remark:

Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

1711 - 1866 activity
No volcanic activity occurred during 1711-1866. Mikri and Nea Kameni were 2 separated islands forming 2 natural bays (Georgios and Vulkano bay). Sulfuric fumaroles in Vulkano bay. Building of a small harbor and ca. 50 summerhouses (!) on Nea Kameni.

1707-1711 eruption: Nea Kameni appears
23. May 1707 - Sept. 1711 -- Formation of Nea Kameni (gr., = "the new burnt island"). Strong surtseyan and effusive activity. Ash-fall and gas explosions. Lowering of the coastline of Thera and Mikri Kameni. ...more info

1650 Kolumbo volcano eruption
27. Sept 1650 -- Kolumbo submarine volcano (ca. 8 km NE of Cape Kolumbo, Santorini): strong surtseyan-subplinian eruption with ash and pumice fall, toxic gasses (>50 fatalities). Generation of a strong tsunami.
more info on Kolumbo volcano

1570 eruption: Mikri Kameni Island appears
Formation of Mikri Kameni (gr., = "small burnt island"). Surtseyan activity, ash-fall and block fall-out accompany the formation of a lava dome which rises above sea level to form the new island Mikri Kameni.

1457-1458 activity
Unclear reports from Athanasius Kircher (1665) and Buondelmonte (1465/66) indicate that either a part of Palea Kameni collapsed and disappeared or a new island between Palea Kameni and Thera was built.

726 AD subplinian (?) eruption
Strong explosive probably sub-plinian eruption. Records by Nicephoros (758-823), Theophanes (752-818) and Cedremus (after 1059). Probably small effusive activity following the pumice eruption creating the black blocky lava lobe at Agios Nikolaos (the small harbor bay with the church and hot iron springs).

46 - 726 AD activity
No reports of activity are known from that period. There was either actually no eruption or it has not been recorded.

46 AD eruption - appearance of a new island
Appearance of a new island that probably grew together with Hiera and formed the basis of Palea Kameni. Descriptions by Roman historians Seneca (4 BC-65 AD), Livy (59 BC-AD 17), Pliny the Elder (23-79 AD), Dio Cassius (ca. 200 AD), Aurelius Victor (4th century AD), Philostratos (ca. 200 AD), Orosius (5th century AD), Cassiodorus. (418-562 AD), Labbreus (1670). Probably surtseyan activity with updoming of the sea-floor.

197 BC eruption: appearance of Palea Kameni
Formation of an island called Hiera (gr., = "the holy one") inside the caldera, probably a precursor of Palea Kameni. Documented by greek and Roman writers: Strabo (66BC - 24 AD), Plutarch (ca. 40-120 AD), Pausanias (ca.120 AD), Justinus (2nd century AD), Eusebius from Cesarea (270-340 AD) and Ammianus Marcellinus (ca. 330-400 AD). Probably surtseyan activity with updoming of the sea-floor (comparable with the 1707-1711 events).

1613 +- 13 BC Minoan eruption
The most recent plinian eruption on Santorini occurred in the late Bronze Age at around 1613 BC and is known as the so-called Minoan eruption. It is one the biggest known volcanic explosions in younger time,- and one of the most studied, but still most mysterious eruptions of all time-. It devastated not only Santorini, but had a deep impact on the whole of the Eastern Mediterranean. Perhaps it even had serious world-wide effects and changed history.
Size of the Minoan eruption
Dating of the Minoan eruption
Still today, one can see its deposits, the characteristic, tens of meters thick layer of white pumice and ash that blankets most of the surface of the island group. The eruption changed the shape of the island itself dramatically: it is now believed that before the eruption, it had the shape of an almost complete ring that enclosed an earlier, shallower caldera.
Large sections of island collapsed into the emptied magma chamber after the eruption, literally disappearing under the sea. The ring-island was breached to the W and NW, and the caldera was significantly widened and deepened.

Santorini Volcano FAQ

+When was the last eruption of Santorini volcano?

The last confirmed eruption of Santorini occurred in 1950.

+How often does Santorini volcano erupt?

Since 197 BC, Santorini volcano has had at least 11 historically documented eruptions. This means that it erupts on average every 202 years.
Many eruptions of Santorini have lasted more than one year. In total, the volcano has been in eruption during 26 out of 2222 years until now. In other words, Santorini has been active at least one in 85.5 years on average. Note that this value is likely an underestimate, because the known history of eruptions from Santorini is likely incomplete, especially further back in time.

+How active is Santorini volcano at present?

Santorini volcano is infrequently active: Since 1900, it has had 7 eruptions, and been active during 7 years out of 126 as of now. This means, Santorini has been in eruption one in 18 years on average. The last eruption was in 1950 and ended 75 years ago.

+When was the largest eruption of Santorini volcano?

The largest eruption known from the younger geological history of Santorini volcano occurred around 1610 BC. It ranks as a sub-plinian eruption with a magnitude 4 on the VEI (Volcanic Explosivity Index) scale.
