We haven’t seen a large eruption since Tambora, 200 years ago. That is a good thing: the world has had enough troubles in that time, and a major volcanic disaster was really not needed. There has never been a major eruption in a highly developed area, and we don’t know how resilient a…
After writing the Woolly Mammoth Guide to Icelandic Volcanism I vowed to not write about Iceland for a while. That comment bit me in the posterior rather quickly. Since the cessation of the Holuhraun eruption the central volcano Bárðarbunga has been highly seismically active. Many people have fervently believed that this has been due to…
In the previous part we learned that Grimsvötn indeed is able to produce large scale eruptions as we looked closer into the Saksunarvatn tephras. The first part can be found by following the link below. http://www.volcanocafe.org/grimsvotn-the-saksunarvatn-tephras/ This time we will look into what this new information might mean for the future eruptions of Grimsvötn. But…
Sometimes our readers send in questions to us that literally sends the writers into a frenzy of volcanic exploration. This week’s question was about if the area between Fort Rock and Chemult in Oregon is indeed a large caldera. The area is situated south of the eastward Cascade volcanic range south of Newberry (Paulina Peak),…
Few of our readers have missed the anomalous M6.2 earthquake that occured 20 km WNW of the Aniakchak Caldera. In this article we will go through the details of the earthquake and the possible effects of the main-shock and the series of after-shocks. According to the Alaska Earthquake Center the waveform of the initial 6.2…
This is a repost of an article from October 28, 2013. The Caribou was standing on the plains 30 kilometers away from the mountain; it had not fled the roaring mountain more than that. After all, the ash was driven by the fierce wind to the north, and where it stood to the west in…
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…
Lake Toba is a beautiful place. The largest and deepest lake in Southeast Asia, it contains an island (Samosir) almost the size of Singapore – the fifth largest lake island in the world, and the largest island-within-an-island. Samosir contains two smaller lakes, Lake Sidihoni and Lake Aek Natonang – the former even contains its own…
It has often been pointed out that the deadliest volcano is the one you did not know about. This is our dilemma. When you try to identify the potentially most dangerous ones, by necessity you have to go out on a limb to find those that are not well known nor well studied and there…
Few volcanoes on the planet represent such an awesome sight as the majestic Mount Cameroon. It stretches from the edge of the Atlantic at Bakingili Beach and reaches an astounding height of 4040 meters. Due to its prominence it is regularly dusted with snow at the top. Mount Cameroon, or as I am used to…
