Posts about volcanoes in Central and South America.
An effusive eruption began on La Soufriere volcano on St Vincent (St Vincent and the Grenadines) island in the eastern Caribbean Sea in Dec. Note that this is currently an ongoing dome building eruption.Continue Reading
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.
