I remember, as a teen, I loved rummaging in my mother’s enormous picture postcard collection – what a treasure! There was a photo in it that I never forgot in my life: An old Orthodox church sitting on a ridge high above a village and, behind the church, the humongous Continue Reading
Seeing that SERNAGEOMIN recently has included the Reclus volcano into group III of the assessment of their volcanoes, according to hazards they may pose to the population, I had another go at finding out more about it. Continue Reading
We find that our blog has been alive, growing and changing for 5 years, which has surprised us, as we didn’t think it was that long. Many, many thanks to you, our readers, for your loyalty, your interest, support and comments. Continue Reading
In many descriptions of volcanoes and their eruption histories we stumble upon the terms Tuff, Tufa or Ignimbrite. Most every self-respecting volcano has one or all of them. Generally it becomes obvious from the context that they refer to widespread deposits of volcanic materials. But what exactly is an ignimbrite?, is it different to tuff?, and where do they all come from?
Tuff and ignimbrite are clastic rocks composed of volcanic Continue Reading
You may be about 90 and no longer able to travel the volcanoes of the world; you may be a young student lacking the funds as well as the friends willing to climb your favourite volcano with you; you may be an inveterate couch potato, or, you just want to spend some relaxing armchair time during the holiday season – don’t despair!

As so often, and generally without intention, I have hit upon yet another volcano that has all the trimmings of a beast but seems not really to be recognised as such. Up to a few years ago there have been very few studies to find out about the seismological and structural properties of the volcano. Volcán Ceboruco is considered among the five volcanoes with the highest risk in Mexico, and the second most active after Colima volcano in the western Trans-Mexican Volcanic Belt. Yet, scientists had to point out, in a 2016 study, “that every effort should be made to monitor its seismic activity”. Continue Reading
Today our fancy takes us to the NE of Spain. Just to the corner where the Pyrenees mountain range meets the Mediterranean Sea, to the province of Girona in Catalonia. For millions of us European tourists the Mediterranean Costa Brava with its golden beaches is a household name. As in so many other touristic spots in the world, one could ask, how many of the sun worshippers would have known that, some 60 km inland, there is a volcanic field to be visited? Continue Reading
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! Continue Reading
About everybody knows that Guatemala has three very active volcanoes: Fuego, Pacaya and Santa Maria’s dome Santiaguito – but did you know that a staggering 324 eruptive centers have been identified in that country?
