In the previous article I was talking about the volcanoes in Argentina, in the Andes, near the latitude of Buenos Aires, only a little more to the south: Payún Matrú, Tromen, and Domuyo. Now we cross the border into Chile, into the Maule Province of Chile. Here, almost exactly along the topographical divide between the…
We owe our existence to our ever-changing and yet passive climate. Unlike other planets in the universe, here it doesn’t rain molten glass or frozen acid, nor does it have super sonic winds destroying everything in its path. However, the climate isn’t without fault as it is sensitive to very small changes with atmospheric composition.…
It is a narrow but passable road, or at least it used to be. It begins at the Saddle Road which crosses Hawai’i between Mauna Kea and Mauna Loa. Both mountains have observatories at or near the summit, but while Mauna Kea is busy day and night, the Mauna Loa observatory is a much quieter…
Growth is in. Politicians and leaders (not always the same thing) want their country to grow. Nowadays this normally means economic growth: the wish to become more wealthy. It would make those leaders more popular, and may provide them with more resources to spend on whatever leaders spend money on. In the very different world…
Rough winds do shake the darling buds of May In the previous posts we looked at the Eifel volcanics, the Laacher See (the largest eruption in western Europe for the past 1000 centuries), and volcanic dating of the Younger Dryas. The eruption occurred a bit over a century before the sudden cooling. But what caused…
The volcano helpfully called ‘Vulcano’, one of the islands, north of Sicilyhas give its name to all volcanoes in the world. Vulcano last eruption was in 1888-1890. During the long repose period, a settlement has grown from a few houses to villas and hotels. Frazzetta et al. wrote in 1984 (quoted by Boris Behncke) “A…
We continue with a list of volcanoes capable of producing a VEI-8 eruption from least to most likely and taking into account the factors that I explained in the previous post, here. Next volcano capable of a VEI-8 is… 6. Long Valley-Mono (USA) The volcanism of the western United States can give you a headache…
Guest post from Tallis Ever since I was a kid, I’ve always had a fascination with meteorology, Thunderstorms in particular, but the entire science as a whole. I am a self-taught weather person, who has read books, watched lectures and talked to storm chasers about their interests. While volcanoes are almost as interesting to me,…
As some has noted there has been quite a bit of activity in the last week at a volcanic feature that we have chosen to call Greip located north of Grimsvötn. We have previously written quite a bit about this feature and even gone so far as to state that it might be in a…
I originally submitted this article on November 9, 2012, Due to PHILVOCS raising the alert level for Taal from “No Activity” to Level 1 on 8 Oct 2019, as pointed out by reader Andrew McNeil, we felt that a quick rerun was in order. Before we touch that, let me add that the data in…
