The chamber of molten rock beneath Santorini's volcano expanded 10-20 million cubic meters -- up to 15 times the size of London's Olympic Stadium -- between January 2011 and April 2012, according to a new survey. The growth of this 'balloon' of magma has seen the surface of the island rise 8-14 centimeters during this period, the researchers found.
