“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.“
(Father João Ignácio da Silveira, May 1808)

A *PAMS* Volcano in Europe? CIOMADUL / CSOMÁD (🇷🇴)

GEarth view of Ciomadul volcano, looking South.

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!

I guess this has changed now; a volcano in the neighborhood has always proved a recipe for visitor attraction!

Rincón de la Vieja is one of those volcanoes that don’t make headlines with fiery lava streams and end-of-world scenarios. Presently, the biggest news from it are about yet another phreatic explosion, and the most exciting photos show a pale steam plume fading away, at best with a bit of ash mixed in. Moreover, the videos of ensuing lahars we have recently seen show
