Some nations seem decidedly unvolcanic. They lack the geology and the temperament for eruptions. Take Norway – a no-nonsense nation which prefers a bit of solitude and does not go for attention grabbing. A search for Norwegian volcanoes does come up with some good examples, but these are distant islands which Norway acquired accidentally. Of…
The story begins with Japan’s iconic volcano. Mount Fuji has become the poster child of volcanism – it is what every volcano strives to be. This is the most climbed mountain in the world. The spring-time view of Mount Fuji framed by cherry blossom is the very emblem of Japan. The reflection of Fuji is…
During August 2021, reports came in about an eruption in the ocean south of Japan. The volcano was new to me: Fukuto okanoba. It sounded like something from star wars. It was a friendly explosion, meaning no one was inconvenienced by it. The submarine explosion had produced a tephra raft 60 km long, plus an…
Today is the 10 year anniversary of the Tohoku earthquake. The M9 off the coast at Sendai, Japan, was impressive enough by itself, but the main impact came from the huge tsunami that followed. I remember it well. My lecture the previous day had been on the physics of tidal waves and tsunamis. I had…
Rhyolite has more silica, this makes it more viscous, more explosive and in turn more dangerous. Basalt is the opposite, fluid, well-behaved, safe. This could be a phrase out of any geology textbook, I can almost feel some readers getting ahead of me and thinking what I am obliged to say. But there are exceptions!…
Nishinoshima is in many ways the perfect volcano, it is constantly doing firsts, and spectacular and unusual things. Normally volcanologists would gather nearby and play lip-banjo at its antics. But since it is far out into the ocean and is so inaccessible most miss this beauty of a beast. In November and December of 2013,…
The little part here is highly metaphorical, or perhaps I should say challenged in regards of prominence. The volcano in question is once more Nishinoshima. Back in 2013 when it rumbled back to life it was all the rave, but nowadays I bet that even most volcano afficionados have missed the return of the ocean…
Iwo Jima has long been of particular interest to VC. It is an enigmatic volcano with a very human history. One of the pivotal battles of the second world war took place here, at immense human cost which arguably changed the way the war ended. The island remains home to the Japanese navy, and visits…
