The biggest volcanic eruption recorded in Santorini is, according to all research to date, the catastrophic Minoan-era eruption. Repercussions from such an eruption would have been massive, not only for Santorini but for the greater Aegean area and the eastern Mediterranean, particularly because it may have created a tsunami that would have swept the surrounding coasts. Today, scientists can generally predict that such an eruption likely won’t take place soon or even in the remote future. The predicted frequency of such events in Santorini is every 15,000 to 20,000 years. It has been only 3,600 years since the last great eruption. All research from Santorini indicates that 2-4 kilometers below the Kamenes islands are molten rocks and magma chambers which will, in the long-term future, feed the next volcanic episode. It’s impossible to predict when that will happen with any precision, since nature is a mercurial force. What scientists can do is be able to predict, between a few months and a year in advance, when the volcano will become active again.
