Like all other original branches of science, geology has split and evolved into a multitude of sub-species such as geophysics, petrology, mineralogy, volcanology and seismology. The science that deals with natural and artificial gemstones, gemology, is considered to be part of the geosciences and specifically a branch of mineralogy. If we disregard artificially generated radioisotopes,…
As we move inexorably towards the end of yet another year, it is inevitable that we think back on what the old year has brought. One of my favourite memories of 2015 is the visit we; Carl, Shérine and myself, paid to a couple of volcanic monuments in southern Sweden; Rallate and Jällabjär, at the…
Living on a constantly changing and evolving planet, unravelling the past is not an easy task as resurfacing, erosion and continental drift continuously eradicates what has gone before. Even after the last remaining “White Areas” on our maps of the Earth’s land masses had been filled in about a century ago, great discoveries that would…
A recurrent theme throughout this series has been the unknown and understudied which with our current understanding of geology and volcanology could pose a danger to millions of people. From the water-enriched and thus highly explosive magmas of Kelut to Aso, the problems of a giant edifice such as Mayon, the understudied Taal and Bali…
It has taken a long time, far longer than originally intended, to bring the New Decade Volcano Program to a successful conclusion. Indeed, there was a point during the summer at which it seemed that it would be left unfinished as after writing two of the first four articles Carl found himself in a position…
It is interesting to note that not long after we had revealed Aso as #4 in our NDVP series, activity seemed to intensify and cause expectations of a large eruption, possibly even the “Big One”, within the near future. Such excitement is only natural but is Aso really on the verge of a major…
Despite the high-falutin’ title, this is not a complete guide nor is it compiled by a pro. It’s more of an introduction by someone who has made all the mistakes possible and, hopefully, learnt a thing or two in the process which I now try to pass on. As amateur volcanophiles, we are limited to…
Few cities around the world can claim a more beautiful setting than Managua (pop 2.223 million, 2012), Nicaragua, on the shores of tranquil Lago Xolotlán, Lake Managua. When the Conquistadores arrived, Masaya volcano 20 km from today’s Managua was in eruption and provided Europeans with their fist view of a lava lake. In a letter…
I suppose not many will be surprised by this choice as “googling” Campi Flegrei immediately yields results such as “Campi Flegrei: The Massive Italian Volcano that Will Kill Us All (Or Not)” (Time, Aug 08, 2012) or “Italian Supervolcano Could End Eurozone Crisis the Easy Way” (Smithsonian, Aug 06, 2012). Indeed, both Carl and myself…
This is a question that gets asked regularly and in particular when there is a lot of earthquake activity going on. Surely this must “mean something”! Well, yes, but not necessarily something volcanic. In fact, most of it is not volcanic at all but tectonic as the North American and Eurasian Plates slowly separate, driven…
