… and not just a romantic gateway

Dear friend

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 Minoan eruption.

During this eruption…

  • Sixty million cubic meters of equivalent dry rock of magma in the form of pumice and ash flew through the air at a height of 36km above the island, covering the island.
  • Volcanic ash traveled eastward and spread in the eastern Mediterranean and Asia Minor deposited an ash layer of 30cm thickness in Rhodes and Kos and 15cm in lakes of Asia Minor.
  • Traces of ash have been found in the glaciers of Greenland,
  • While the effects of the volcanic winter, induced with a reduction of the temperature by 1-20oC, were recorded in tree trunks in the US and Asia.

The center of the explosion is located between Fira and Nea Kameni. Solids and gases hurled from the volcano and created a big gap in which precipitated the central part, forming the current caldera. The result was the creation of huge tidal waves that swept the coasts of the Aegean and the eastern Mediterranean.

Although at present dormant, Santorini has been active several times in recent times. This activity built the dark-colored islands of Nea and Palea Kameni inside the caldera. The last eruption on Nea Kameni occurred in 1950 and activity was recorded from 2011-2012. At present, Santorini is dormant, and volcanism manifests itself as fumarolic activity and hot springs around the islands.


  • Santorini is an archipelago of five islands, the bigger Thira, Thirasia, Aspronisi, New and Old Kameni, and has a total area of 90.6 square kilometres (35 square miles), with the main island, Thera, measuring 73 square km.
  • The Santorini archipelago was originally a single island which was destroyed by the devastating Minoan volcanic eruption, one of the largest volcanic eruptions in recorded history (7 on the VEI scale out of 8!) – 4 times the power of Krakatoa!
  • It is said that one of the locations on the original single Santorini Island, now dubbed as ‘Akrotiri’, is possibly the lost city of Atlantis, a Greek-originating legend, that was described by Plato.
  • ‘Santorini’ was named during the Latin empire after the cathedral Saint Irene, and was originally known in the Greek empire as ‘Kallisti’ (the most beautiful), ‘Strongili’ (round) and ‘Thera’ (after King Theras) and the latter is now the official name.
  • Santorini is one of the few places on earth where you can visit and swim at white, black and red beaches. The water at the black beach is warmer due to the heat absorbing black lava rock.
  • Santorians would build their houses inside the island’s volcanic walls and slopes to protect themselves from the weather, called the ‘cave houses’. Many have been restored today although a lot of the buildings were destroyed by an earthquake in 1956.
  • The land on Santorini is called “aspa”, and is made up of volcanic ash, pumice stone, and small pieces of solidified sand and lava. It is very rich in minerals.
  • Although its climate is dry, the volcanic ash soil makes for some really tasty tomatoes, eggplants and courgettes… and extra-ordinary vines! There are over 100 varieties of grapes in Santorini.
  • Locals say “There is so little rain on the island of Santorini, that wine in more plentiful than water.” The farmers and vineyards follow ‘anhydrous’ techniques to grow crops. The wine grapes are grown with no irrigation on the ground in bunches rather than on vines to absorb the humidity from the soil and protect themselves from the strong winds.
  • Pumice stone on the island was a huge export business until recently and you can observe the mines even from the main town of Fira.
  • The Venetians built 5 fortified castle-selttements around the island to protect it from pirates. Since the island was inhabited by the Venetians, many of the churches are not Greek Orthodox, but rather Catholic.
  • Santorini has quite a few hot springs and you can distinguish the warmer waters because of the color change to a murky brown.

Spring is really the best time to experience nature and observe flora and fauna in Santorini. By Easter it has been raining for quite a while and the island is unrecognizable. The hills in spring and during easter are carpeted with lush vegetation… the flora is quite spectacular!

I would recommend if possible to travel out-of-season, in April, May, June, September, October or November. During these months, the islands are more relaxed and accommodation and travelling is better value.

In April, May and June, the temperature of the sea water is a bit colder, but you can still swim. In September, October and November the islands are more dry and less green but the water temperatures of the sea are warmer.

Outside the tourist season (December – March) you can expect all kinds of weather, from short thunderstorms, wind and even (rarely) snow to lovely sunny days on which everybody rushes to the beach and a dip in the water.

If you wish to discuss the above or any other matter please don’t hesitate to contact us either by phone at +30 6976 761492 or email at info@nofootprint.gr

We look forward to hearing from you soon.
