Nothing much has happened in the intervening years but of course one day it will. There probably be clear signs of this happening and at the moment it's only background. I have just returned from the canaries where there is quite a bit of volcanic activity but I didn't loose any sleep over it. Enjoy your holiday.

Even there are changes, it will take years or even decades until a new eruption may take place.

I am on Santorini right now and there are more serious dangers than an eruption like in 1950. The traffic and the uncontrolled mass of rented cars and motor bikes are much more dangerous than the volcano.

I dont know where on earth but just in case because of the ongoing phenomenon i said to watch out :)

so there is absolutly no reason on earth that another volcano could not be about to come through at this point. its happening elsewere so why not.reasently geologicly speaking its happened below iceland below el hierro in the canaries and its happening in hawaii.

They are of the order of a few (say 5) cm per year. A movement of a distance of 50 km takes 5,000,000 cm / 5 cm years = approx. 1 million years.

The shifts from one established volcanic vent to another is probably not gradual, but happens with jumps from one vent location to another, but at timescales proportional to the movement.

So, while it is not impossible, it is EXTREMELY unlikely that new volcanic vents are opening up for the first time now about 50 km SW of Santorini, as a consequence of the southward migration of the subduction zone.
