A thick ash layer cover Strongyle island as a whole yet there is no safe conclusion on how much thick it was because of the decay to which these layers have been subject to as well as the rainfall that have washed the pumice up at the slope areas. A few pumice remains can be seen nowadays at Prophet Helias area which is located at a high altitude whivh could lead us to the clue that this area was not affected by the eruption. However, it must have been the rain and the wind that removed the pumice.

The Minoan eruption brought a new shape to Strongyle island. A segment of its earth, including the pre-volcanic island, disappeared from the centre of the island creating a 500 meters deep caldera, while some earth pieces appeared at its periphery expanding the east side of it and unifying it with Monolithos island. So, Strongyle island broke to three pieces; Thera, Therasia and Aspronisi.

There is no doubt that the Minoan eruption affected the islands near Santorini. At least the bamgs of the explosion must have been heard by the inhabitants of Anaphe and Rhodes islands while the poisonous gases emerged from the volcano must have been expanded to a wide area around Strongyle. Pumice layeres have been found on both islands, transferred there either by the rain or by the sea as it was laid on the sea surface. Pumice has also been found in several Aegean coasts such as Crete, Lemnos, Anaphe and Samothrace islands as well as in Cyprus and Israel.

Tidal waves were caused, during the Minoan eruption, due to the collapse of the volcanic column to the east of the island, just like the one occused during the volcanic eruption of Krakatau. Huge rock masse fell into the sea causing tidal waves to Crete island. Tidal waves were also caused during the third phase of the Minoan eruption due to the collapse of the magmatic chamber which resulted to the creation of the north basin of the caldera.

The pumice layers that floated in the sea for months made it difficult for ships to sail and for fishermen to fish in a large area of the Aegean Sea. At the same time, a great part of the corps of the surrounding area must have also been destroyed so people suffered from hunger. What is more, the particle that stayed in the stratosphere for a long time, caused climate changes in several areas of the earth.


Several scientists have connected the decline of Knossos with the Minoan eruption of Santorini. The date of the decline of Knossos has been placed by researchers in the same era as the eruption. According to one scientific theory, the earthquakes and the tidal waves that followed the eruption caused serious damages to the settlements of north Crete, as it happened during the recent eruption of Krakatau volcano. However, nowadays the destruction of Knossos palace is not considered to have been caused by the Minoan eruption because the palace had been built 60 m higher that the sea level. This means that the tidal waves which possibly arrived in the northest coasts of Crete, could not have reached the palace. It is possible that the coastal settlements and anchored ships at these area have been destroyed by the huge waves. Moreover, the destructions in Crete were possibly due to earthquakes, fires and even political causes.


According to historical resources, the bad climatic period of China was the same as the one of the Minoan eruption. Fog consisting of swinging practices which prevented the sun rays from lighting the country, cold and unsteady weather, driving rain falls, floods and a long drought period that occurred in China are considered to have taken place 1,630 BC thus they are possibly related to the Minoan eruption.
