NEMRUT DAğI* 🇹🇷 – ANOTHER CANDIDATE FOR A FUTURE “DECADE VOLCANO”?

Preliminary note:
I have started work on this post long before the latest unacceptable political developments, so, it is pure coincidence that it’s getting published just now. In the region around Nemrut Dağı live Kurdish, Turkish and Armenian people. I wish peace for them all – and hopefully, my post will inspire interest in this wonderful part of the world.

~~~

Nemrut Dağı* volcano has so many interesting features within and outside its caldera that it would probably take a several-week-long holiday do visit and explore them all. It has produced many colourful layers in ignimbrites during its various, mainly Plinian eruptions, as well as lava domes and obsidian flows, open fissures, steam chimneys, lava caves, what have you. I think this will become my favourite volcano!

NISYROS – (re-)Visited

Nisyros: Caldera view from above Nikia village.

So far, when I wrote about volcanoes around the world, I could only dream of ever visiting them. Researching for my first Nisyros post, though, it occurred to me that the idea of a short holiday there was not entirely out-of-bounds. It didn’t take long and I had convinced daughter & granddaughter to come with me. We travelled to Nisyros in October, and, what can I say – it was a wonderful, if too short a holiday! Here are some impressions, thoughts and photos from our visit.
