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?
Papandayan is the volcano you can actually see on satellite images (e.g. Google Earth) even from a view point 800 km above ground – it is the white patch of a collapse scar that stands out in stark contrast from the dark green forest. The volcano sits at the southern end of the Kendang-Papandayan mountain range.
G. Papandayan is generally said to be 2665 m high but there seems to be some confusion as to location and actual height Continue Reading
Update, Aug. 2019:
In the five years since this was first posted, science continues to grind away, answering a few questions which in turn create a bunch more questions. The Baillie tree ring / ice core team is increasingly of the opinion that the 535 – 540 AD global cooldown was caused by huge volcanic eruptions, at least two of them bracketing the period. A team including Robert A Dull published a paper August 16 entitled “Radiocarbon and geologic evidence reveal ilopango volcano as the source of the colossal ‘mystery’ eruption of 539/40 CE” that appears to nicely define the most recent end of that bracket.
When the news reported multiple volcanoes erupting in Vanuatu – when new volcanoes appeared near Tonga Islands – when earthquakes shook most of Melanesia left right and center – I have often wondered if, or why, there are no volcanoes on the Fiji Islands? Well, you probably guess the answer – of course there are! They are just not very busy at the moment, so they may escape our attention, and may lull the residents in false security, too. The three that are mentioned by the GVP are Taveuni and Koro Islands, and Nabukelevu which occupies the SW end of Kadavu Island. Continue Reading
