Guest post from Tallis An Appeal for Advice I thought I was finished with Chiles-Cerro Negro, I have already written two articles on this volcano before detailing my thoughts, issues, concerns, and scenarios. Chiles-Cerro Negro is a volcano that has been restless for almost 7 years now, it has had large swarms and other signs…
It was on a hike to Mauna Ulu, many years ago. The path from the Pu’u Huluhulu trail head had been easy to follow – at first. It quickly left the shrubby vegetation near the road behind, and the scenery became one of total devastation. The markings of the path became fewer and fewer. Once,…
Decision taken after the EU expressed concern This was of course our April-1 story, aimed to amuse rather than fool, in these dark days. The idea came from Lughduniense and Geolurking, and images were artfully created by Lughduniense. Carl proclaimed it ‘wonderful’ and Manning was happy to ‘help’. And I just did the writing up.…
Painting by Borge Ruud, undated but probably 1947 Of all the volcanoes of Iceland, the most famous is Hekla. It is one of five recognized stratovolcanoes in Iceland, and of those it is by far the most active. Over the past millennium, there have been around 20 eruptions of Hekla, accounting for 13% of all…
If you are now wondering why you never heard of this, this was a prediction, not an event. The volcano decided otherwise 38 per cent of all eruptions in Iceland come from Grimsvötn. It is an amazing number: this hidden volcano, invisible and unreachable to all but the most hardy explorer, is among the most…
Edinburgh – home of the Scottish Parliament, Military Tattoo, Princes Street and gardens, Scott memorial, Murrayfield, Valvona and Crolla’s food emporium, sundry pubs (!), the fringe, volcanoes … eh, volcanoes? Surprising as it may be to some people, Edinburgh plays host to a great variety of igneous rocks. The most obvious, and in our case…
The Wrangell Mountains are Alaska’s most secretive volcanoes. We have looked at what they are (post I) and how they may have formed (post II). This area of Alaska has suffered the brunt of the most recent continental collision on Earth, and the Wrangell Mountains are an immense scar from this monumental accident. But there…
Iceland does it rather well. Over the 1100 years or so since the Viking settlement, it has erupted some 63 km3 of lava, the large majority of it basaltic. A similar volume of tephra was also produced. The East Volcanic Zone is the prime suspect for any eruption, and with good reason: it is responsible…
Sometimes, a volcano is nothing more than a hole in the ground. There are beautiful, though deeply eroded, cone volcanoes around Taal: Mount Banahaw, Mount Mariveles, Mount Natib – especially the latter also has a large caldera. But Taal is not like that. It is a lake, with only a little cone sticking out. The…
The Wrangell Mountains are an unexpected treasure in a land of riches. Here are shield volcanoes higher than Mauna Loa, which have grown up over the past 5 million years. It stands alone amidst the crowd. From the Wrangell Mountains, other mountains ranges can be seen in every direction, but none of those are currently…
