Stories of Geography: Santorini Volcano

If you have been to Santorini you will not know that island is Volcanic as part of a huge caldera, surrounding the Volcano of Nea Kamini. If you arrived by boat then you will have travelled past the volcano and seen tourists trekking their way to the top. If you were able to drag yourself away from the towns, sunsets and beaches you might have taken a boat trip out to learn a little bit more, even to swim in the hot springs on the far side.

Our knowledgeable guide informed us that there would be no chance of an eruption during our visit, though the magma chamber was slowly being filled up as the African plate is subducted under the Eurasian. As this happens the oceanic crust is destroyed ready for the next eruption. Currently the volcano is classed as dormant, as a reminder that the status will one day change we kicked up some dirt and just below the surface the temperature of the stones was enough to burn your hands if you weren't careful.

The volcano island is made up of several craters relating to previous eruptions, the most recent being 1950. You can see gases escaping from cracks in the rocks as you stare into a graveyard of the poorly secured hats littering the crater sides.

Another key point to notice is the different colour of the igneous (volcanic) rocks, this is due to the rate at which the rock cools and the amount of oxygen reacting with it as this happens.

It is unlikely there will be another eruption on the scale that destroyed the town of Akrotiri, Greece's very own Pompeii. It has been difficult to date to the biggest eruption, it was sometime during 1600 BCE which impact the Mediterranean directly, causing destruction to settlements on Crete and potentially impacting global climate patterns, records in Egypt describe significant changes around the same time.

Once you've climbed up what better way to finish the trip than heading to the far side of the volcano for a swim in the hotspring where you notice the change in the temperature as you move closer to the island. The water is supposed to be good for your skin, though not so good for a white swimming costume!!
