Interesting article on Santorini which states a giant balloon of magma has inflated under Santorini only a small part translated.
,,A new study published in ‘Nature Geoscience’ suggests the Chamber rock melted under the volcano of Santorini expanded between 10 and 20 million cubic meters – up to 15 times the size of the London Olympic Stadium – between January 2011 and April 2012.The growth of this “balloon” of magma has made the island surface amounts between 8 and 14 centimeters during this period, according to a team of researchers led by scientists at the University of Oxford. The results come from an expedition funded by the Natural Environment Research Council the natural environment Research Council images that used the Global Positioning System receivers and radar satellite GPS, for its acronym in English which can detect movements of only a few millimeters of the Earth’s surface.,,
The full report which will need to be translated can be read on:

It’s a sizeable intrusion of magma, about 9-16 cubic km.
Basically if 10% of that magma erupts (not counting with old magma), then we will have a 1-2 cubic km eruption, which is a large VEI4 to a small VEI5 sized eruption. This is roughly slightly larger than the previous eruption of Grimsvotn. The 2011-2011 inflation of Santorini is however a bit smaller than the one observed for Grimsvotn before its 2011 eruption.
I think Santorini at the very least will do a VEI4, similar to Eyjafjallajokull, if not something identical to Grimsvotn.

There may be a swarm starting near the Aegean Sea there have been 4 EQ’S in just over 10 mins.
Just been a 5th one near Romania.
