Santorini volcano, Greece: new radar measurements show decreasing trend of uplift in 2012

A new study was published about the recent uplift detected on the volcanic island of Nea Kameni in the center of the Santorini caldera. The data were obtained using ESA's Envisat satellite and the measurements show that the northeastern part of Nea Kameni experienced an uplift of about 5 cm in 2011, while other areas of the volcano rose some 3–4 cm. This inflation was associated with the elevated seismic activity during the past months and can be interpreted caused by the injection of fresh magma under the the volcano.

The latest data also show that during the first months of 2012, the rate of uplift has decreased. This correlates well with a decrease in seismicity.
A possible interpretation could be that the intrusion of magma is coming to an end, and an eruption in the near to medium future is less and less likely.
"After evaluation of local seismic activity, deformation and physicochemical changes, [we] concluded that during the last months the volcano presents a very limited activity, much lower than that of 2011," said Prof. Kosmas Stylianidis, Head of the Special Scientific Committee for the Monitoring of Santorini Volcano.

Seismic activity at Santorini volcano, Greece: small earthquake swarm SW of the island between 28-30 April

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. [more]
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. [more]

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. [more]
