Santorini volcanoCaldera (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 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. Santorini webcams / live data

After 7 years of closure, following the tragic accident of the roof collapse of the newly built shelter in 2005, the archeological site of Akrotiri on Santorini (Greece) is now open for visitors again. [read all]
A small earthquake swarm has been occurring at the western margin of the caldera during the past few days. The swarm consists of about 10 quakes of 1-2 magnitude at 7-8 km depth. [read all]

During the past days, a new earthquake swarm has been occurring near Santorini. This time, it is in an unusual location about 15 km south of the island, not on the principal volcano-tectonic SW-NE line crossing the caldera. [read all]

Santorini has remained relatively calm for 60 years since its last eruption in 1950, but started to re-awake in early 2011 with beginning inflation and increased seismic activity under the volcano. ...more [read all]

The earthquake swarm at Santorini island, Greece, which that had started 4 days ago continues with more small quakes inside the caldera at shallow depths of around 6 km. This could suggest another magmatic intrusion the volcanic system. [read all]

After about 6 weeks of calm, another seismic swarm has started yesterday at Santorini, clustered in the NE sector of the island and near the submarine Kolumbo volcano. The quakes are very small and will not have been felt. The largest was a magnitude 2.0 quake on 18 March at 10:37 GMT at 11 km depth beneath Kolumbo volcano. [read all]

The swarm of earthquakes in the Cretan Sea 50 km SW of Santorini seems to be decreasing. Talking with Dr. Athanassios Ganas, head of the Athens Geodynamic Institute, and others, there is a consensus that the quakes are tectonic in origin and not related to volcanic activity (after all, their location is far from the Santorini volcanic system).

The seismic swarm 50 km SW of Santorini continues with a smaller number of quakes than in the first 2 days. 10 Quakes were recorded in the past 24 hours, including a 3.9 magnitude last night at 31 km depth at 22h46:33 GMT. Interestingly, no quakes seem to occur inside the caldera or in the immediate vicinity of Santorini since the swarm to the SW has started. This clearly shows that there is some relationship. What nature this has, is speculation. ...more [read all]

The highly unusual swarm of earthquakes SW of Santorini on the main fault zone that also defines the volcanic vents of the region continues with about 10 quakes larger than magnitude 2 during the past 24 hours. 2 of the quakes were magnitude 4 and 4.7, respectively. ...more [read all]

A 5.3 magnitude earthquake hit about 50 km SW of Santorini on 26 Jan at 04:24:58 GMT. The quake was 28.7 km and most likely of tectonic origin. The location is 48 km SW of Santorini at the end of a tectonic fault defining a graben SE of Santorini and the eastern boundary of the volcanically active SW-NE zone comprising the volcanic vents of the Christiania Islands, Santorini itself, the submarine Kolumbos volcano and several minor submarine vents NE of Kolumbo.

After a serial of strong earthquakes on 26 January the Greeks begin to take the seismic development around and under Santorini serious. Today there have been several earthquakes south-west of Santorini on the Christiana-Kameni-Koloumbos-Fault starting with 5,2 R, 4,2 R end 3,2 R. At the moment, it is unclear how much this is related to possible volcanic activity at Santorini in the future. ...more [read all]
A strong earthquake was reported north of Crete island and south west of Santorini. Officials told to the media "that there is no great danger", but because it was an earthquake on the "Santorini-Fault" people should be prepared for future earthquakes in the region. Probably there is a tectonic movement going on that time. If this will affect the volcanic island of Nea Kameni at Santorini archipel we do not know yet. [read all]
