Seeing that SERNAGEOMIN recently has included the Reclus volcano into group III of the assessment of their volcanoes, according to hazards they may pose to the population, I had another go at finding out more about it. Continue Reading
Special note to our readers:
Many thanks to all who filled in the survey. A few great suggestions have come in. Now we have to think about the “logistics” to put some of them into action. As we are allowed to keep the survey app running to a certain limit of entries we have decided to put the post up in our top menu. Perhaps the one or other of you still want to have their say. Be reminded that you may answer even just one question and then click the “Finish” button. That’s okay – we appreciate every single bit of input!
As so often, and generally without intention, I have hit upon yet another volcano that has all the trimmings of a beast but seems not really to be recognised as such. Up to a few years ago there have been very few studies to find out about the seismological and structural properties of the volcano. Volcán Ceboruco is considered among the five volcanoes with the highest risk in Mexico, and the second most active after Colima volcano in the western Trans-Mexican Volcanic Belt. Yet, scientists had to point out, in a 2016 study, “that every effort should be made to monitor its seismic activity”. 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?
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
