Santorino is the most important of all the 'islands of eruption' belonging
to volcanic chains.*
[footnote] *[I am indebted to the kindness of Professor E. Forbes for the
following interesting account of the island of Santorino, and the adjacent
islands of Neokaimeni and Microkaimeni. "The aspect of the bay is that of a
great crater filled with water, Thera and Therasia forming its walls, and
the other islands being after-productions in its center. We sounded with
250 fathoms of line in the middle of the bay, between Therasia and the main
islands, but got no bottom. Both these islands appear to be similarly
formed of successive strata of volcanic ashes, which, being of the most
vivid and variegated colors, present a striking contrast to the black and
cindery aspect of the central isles. Neokaimeni, the last-formed island, is
a great heap of obsidian and scoriae. So, also, is the greater mass,
Microkaimeni, which rises up in a conical form, and has a cavity or crater.
On one side of this island, however, a section is exposed, and cliffs of
fine pumiceous ash appear stratified in the greater islands.
