Listen up muppet masters - if you have put in a bid for that Greek jewel of Santorini on Ebay, it may be time to quietly withdraw from the auction. Because according to Georgia Tech, things may get rather shaky soon. Literally: "After decades of little activity, a series of earthquakes and deformation began within the Santorini caldera in January of 2011,” said Newman, whose research is published by Geophysical Research Letters. “Since then, our instruments on the northern part of the island have moved laterally between five and nine centimeters. The volcano’s magma chamber is filling, and we are keeping a close eye on its activity.” Because the only thing that Greece, whose primary business is tourism, needs, is for the biggest Cyclades tourist attraction to go up in a pyroclastic cloud.
Newman, a geophysicist in the School of Earth and Atmospheric Sciences, cannot be certain whether an eruption is imminent since observations of such activity on these types of volcanoes are limited. In fact, similar calderas around the globe have shown comparable activity without erupting. However, Newman says the chamber has expanded by 14 million cubic meters since last January. That means enough magma has been pumped into the chamber to fill a sphere three football fields across.
I'm sure nothing will happen.
Imagine the fallout if we do get a volcanic eruption...http://en.wikipedia.org/wiki/Santorini
Santorini is essentially what remains after an enormous volcanic explosion that destroyed the earliest settlements, on a formerly single island, and created the current geological caldera. A giant central, rectangular lagoon, which measures about 12 by 7 km (7.5 by 4.3 mi), is surrounded by 300 m (980 ft) high, steep cliffs on three sides. The main island slopes downward to the Aegean Sea. On the fourth side, the lagoon is separated from the sea by another much smaller island called Therasia; the lagoon is connected to the sea in two places, in the northwest and southwest. The caldera being 400m deep makes it impossible for all but the largest ships to anchor anywhere in the protected bay; there is, however, a newly built marina in Vlychada on the southwestern coast. The principal port is called Athinias. The capital, Fira, clings to the top of the cliff looking down on the lagoon. The volcanic rocks present from the prior eruptions feature olivine and have a notably small presence of hornblende.
It is the most active volcanic centre in the South Aegean Volcanic Arc, though what remains today is chiefly a water-filled caldera. The volcanic arc is approximately 500 km (310 mi) long and 20 to 40 km (12 to 25 mi) wide. The region first became volcanically active around 3–4 million years ago, though volcanism on Thera began around 2 million years ago with the extrusion of dacitic lavas from vents around the Akrotiri.
The island is the site of one of the largest volcanic eruptions in recorded history: the Minoan eruption (sometimes called the Thera eruption), which occurred some 3600 years ago at the height of the Minoan civilization. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of feet deep and may have led indirectly to the collapse of the Minoan civilization on the island of Crete, 110 km (68 mi) to the south, through a gigantic tsunami. This theory is not, however, supported by chronology, in that the collapse of the Minoan civilization did not occur at the date of the tsunami, but some 90 years later. Another popular theory holds that the Thera eruption is the source of the legend of Atlantis.
Still I'm sure there's nothing to worry about...
