Although not for the faint-hearted and wobbly legged, Lonquimay’s summit is a favorite destination with climbers. The reward for their pains is a stunning view all around: In clear weather, up to 14 volcanoes can be seen within a radius of 250 km: Continue Reading

On and off during recent years I caught some headlines about submarine volcanoes in Italy but never got round to read those studies. Since I came across some really Doom-&-Gloom-The-End-Is-Nigh videos I decided to have a closer look at these. And I’ll give the answer beforehand: Yes there is a real risk. And, yes, there is an awful amount of fearmongering. Continue Reading

Just when I think I will be finished with Antarctic volcanoes for a while, along comes a publication that posits one to several mantle plumes stretching from the Antarctic Peninsula to the Ross Sea. As such, it is probably time to discuss volcanoes in the Antarctic Peninsula.

Looking for the right volcano name to use in my post I found only great confusion, even in official sources. Volcán de Santa Ana is the official name given in Spanish, there’s no doubt. However, in articles across the web you can also find it variously called Ilamatepec, Llamatepec or Lamatepec. Faggioli (2013) notes that all those have no base in the native Náhuat language. The initial “I” in Ilametepec is someone’s invention and plain wrong. It has been called Lamatepec in the work of a 19th century researcher, and this name has since become habitually in use locally.

“After another seven days, a fire exploded in the vicinity of the parish of Santo Amaro, where it opened two mouths of fire, such as two great ravines of fluid material, and with such force that on the second day, we encountered more than a moio of fields of lava in the direction of the homes, forcing the people to flight; the vicar, Rev. Amaro Pereira de Lemos, lost his senses and his sister D. Anna Maria de Lemos went crazy.“

Back in the 1980s I have travelled this part of Romania extensively, we hiked and hitch-hiked through villages and landscapes in 4-week holidays for several years – but never did we know there was a volcano – and such an interesting one at that! The travel guide books didn’t mention volcanoes and the locals didn’t care for geology much. I guess this has changed now; a volcano in the neighborhood has always proved a recipe for visitor attraction! Continue Reading
