Gigantic 'Balloon Of Magma' Is Growing Under Santorini - Will The Volcano Be Dangerous Again?





MessageToEagle.com - Santorini Volcano in Greece is the site of the catastrophic Minoan eruption, one of the largest volcanic eruptions in recorded history of mankind and known as the Thera eruption.
The Minoan eruption took place around 1650 BC. and buried the major port city of Akrotiri with more than 20 meters of ash and created Santorini’s famous, present-day cliffs.
The question is: ‘When will the volcano next erupt?’
Santorini has been relatively calm since its last eruption in 1950. Until now. The Santorini caldera is awake again and rapidly deforming at levels never seen before, explained Georgia Tech Associate Professor Andrew Newman, who has studied Santorini since setting up more than 20 GPS stations on the island in 2006.
“After decades of little activity, a series of earthquakes and deformation began within the Santorini caldera in January of 2011,” said Newman.
"“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."

According to yet another survey carried out by an international team of scientists from Oxford University and the University of Bristol, the chamber of molten rock beneath Santorini’s volcano expanded 10-20 million cubic metres – up to 15 times the size of London’s Olympic Stadium – between January 2011 and April 2012.
