In some places, the coastline vanished under thick tuff depositions.

In others, recent coastlines were extended towards the sea.

Elsewhere in the Mediterranean are pumice deposits that could have been caused by the Thera eruption.

Ash layers in cores drilled from the seabed and from lakes in Turkey, however, show that the heaviest ashfall was towards the east and northeast of Santorini.

In addition, the magma underlying the volcano came into contact with the shallow marine embayment, resulting in a violent steam eruption.

The eruption also generated a 35 to 150 m (115 to 492 ft) high tsunami that devastated the north coast of Crete, 110 km (68 mi) away.

After the eruption, the geomorphology of the island was characterized by an intense erosional phase during which the pumice was progressively removed from the higher altitudes to the lower ones.

Only the Mount Tambora volcanic eruption of 1815, Lake Taupo's Hatepe eruption around 180 CE, and perhaps the Baekdu Mountain eruption around 970 CE released more material into the atmosphere during historic times.It provides a fixed point for aligning the entire chronology of the second millennium BCE in the Aegean, as evidence of the eruption is found throughout the region.Despite the evidence, the exact date of the eruption has been difficult to determine.Studies have identified four major eruption phases, and one minor precursory tephra fall.The thinness of the first ash layer, along with the lack of noticeable erosion of that layer by winter rains before the next layer was deposited, indicate that the volcano gave the local population a few months' warning.
