Thank you really much Elektron! Really great links. They are really informative.

One comment about that picture which one shows how nea and paleo cameni created really short period. It means that santorini volcano magma chamber is refilling really fast, it have been erupted many times little by little growing those islands and those islands grow up because magma and pressure grows.

I'm not sure how fast those island grow but looks really fast to me.

Number one about that thing is by the way anak krakatau.
