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?
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.
“The 7th June anno 1656. Att evening wee arrived att Ascention and anchored on the NW side of the iland. On our rightt hand was a faire sandy bay Continue Reading
At the end of last year Peruvian volcanologists had made an announcement that installing a permanent monitoring system to this high-risk volcano was finished… wait, high risk?… I never knew that Nevado Coropuna was that dangerous, more reason to get acquainted with this volcano. Please meet my newest friend: Continue Reading
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.
