Santorini volcano
Caldera (complex stratovolcano) 329 m (on caldera rim) / 128 m (top of most recent lava shield, Nea Kameni)
Cyclades, Greece, 36.4°N / 25.4°E
Current status: normal or dormant (1 out of 5) Santorini volcano eruptions:
1613 BC +-7 years (the so-called "Minoan eruption", one of the largest plinian eruptions during the past 10,000 years on earth)
historic eruptions: 197 BC, 46/47 AD, 726, 1570-1573, 1707-1711, 1866-1870, 1925-1928, 1939-1941, 1950
Typical eruption style:
Dominantly explosive, with effusive activity during intervals. Powerful explosive, so-called Plinian eruptions appear to occur every 10-30,000 years. Construction of lava shields and minor to irregularly spaced subplinian explosive activity during interval times.

Seismic activity beneath Santorini volcano continues to be slightly above normal levels. Beginning since July this year, an there is elevated activity in a SW-NE trending zone passing through Nea Kameni and the submarine Kolumbos volcano NE of Santorini.
The alignment (also known as the Kameni and Kolumbus lines) is a ca. 2 km wide zone parallel to a tectonic horst and graben structure of the crystalline basement of the area. Most of the known volcanic vents of Santorini during the past 2 million years were located on this alignment, more precisely either on its southern boundary (Kameni line) or on its northern boundary (Kolumbus line).
Lacking other data sources, the information visible on the location and number of earthquakes is too weak, other than to vaguely speculate that the current earthquake activity around Santorini could be a precursor to new activity from this volcano. Santorini's last eruption was in 1950.

There are signs of a possible awakening of the Santorini volcano: During the past weeks, an increased number of small earthquakes has been occurring beneath and near Santorini. The quakes (most of them below magnitude 3) are concentrated beneath the center of the caldera and in a broad SW-NE zone crossing Santorini corresponding to the active volcanic trend of the island group. ... read all

Close-up into one of the holes with the branch sticking inside
We are proud to announce a scientific discovery that has been made in close connection to one of our past tours on Santorini: A new absolute date for the great Minoan eruption on Santorini volcano has been published yesterday in the issue of Science Magazine (28 April, 2006). It confirms an early date for the eruption putting it at 1627-1600 BC with very good confidence. ... read all
