“At times, the path is well-marked, but it crosses and intersects with many more that lead nowhere…” 2007 (© Jorge Alonso, via viajeros4x4.com). Approaching Volcán Lastarria from the NW.
GVP said in 2007: “The rarely visited Lastarria has not erupted in historical time, but has displayed strong fumarolic activity for at least 67 years. This is the first Bulletin report ever issued on this volcano; it presents new images of the steaming edifice…”
Not that the volcano wasn’t known as such – persistent fumarolic activity has been reported from the northwestern flanks since the earliest records were made. However, even the most recent eruptions appear to have predated the Spanish colonists: no records of large or small eruptions have ever been found. Yet, in 1900, Dr. L. Darapsky said “Lastarria volcano… is the only one in the district which shows signs of volcanic activity, Continue Reading

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

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.

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 Continue Reading

Sierra Negra volcano in the Galápagos Islands has piqued our attention once again. Reports of renewed activity are getting more convincing by the month. Here we are again – as advertised – at a “second largest caldera” or, more often even “second largest crater” in the world”… NOT! It seems that everyone accepts Yellowstone with its Continue Reading

It’s always good to have a spare volcano in your desert – for scenery, for tourists, for sulfur, for energy, whatever – as long as it doesn’t erupt. There are far more volcanoes in the world which have not erupted in the last 10 000 years than those considered presently active. With most of them we will never know whether they are truly extinct or just keep their heads down. And then there are those Continue Reading

I know, it’s exciting times for volcanoholics when a volcano starts playing up but if you live at the foot of same edifice you might not feel quite as much excitement and hope it might soon go away… Notwithstanding, you might as well be interested what the thing on your doorstep is up to. Some background for this volcano can be found on our post “Poás” from Oct. 2015. Continue Reading

“Socorro Island is a semi-submerged cinder, slightly mildewed, and with the redeeming feature of possessing fresh water, but with the misfortune of being unable to pass it because of the repellant character of its contour (visiting ships take notice). Its single central summit has an altitude of 3706 feet above the deep surrounding sea and should in fair weather be visible from a distance of 70 miles. At first glance it appeared like a large ripe boil but it soon showed signs of discharge; in fact, it proved to consist entirely of Continue Reading
3D rendered image of Isla Benedicto from Google Earth.
The Revillagigedo Islands were discovered in 1533 by the Spanish conquistador Fernando de Grijalva; named by, and after himself, the Count of Revillagigedo who ordered the islands to be occupied in 1790. They are solitary remote islands, of interest only to military, scientists and adventurers; not much has been written about them over time. They gained some fame when Alexander von Humboldt mused about them in 1811, and in 1905 a ship reported that the islands had disappeared from sight. Continue Reading
