muikabochi 208 Posted September 7, 2012 Share Posted September 7, 2012 With eruptions like that, is there any imminent warning signs or does it just.... blow? Link to post Share on other sites
surfarthur 22 Posted September 7, 2012 Share Posted September 7, 2012 I'm not a volcanologist, but from my understanding, there could be some "bulging" in the hours or days before an eruption, on the other hand, an earthquake could trigger it without any warning. From rt.com Researchers published evidence in May that Mt. Fuji might even collapse if a newly-discovered fault-line underneath it were to shift. This could be triggered by various factors, including slight tremors in the surrounding area. Link to post Share on other sites

grungy-gonads 54 Posted September 11, 2012 Share Posted September 11, 2012 Nope. About Fuji, Scientists say last year's Great East Japan Earthquake has greatly increased the pressure of the magma chamber underneath Mount Fuji. The pressure is now higher than it was the last time the volcano erupted more than 300 years ago, scientists say, according to a report Thursday. Mount Fuji, in Shizuoka Prefecture, last erupted in 1707, less than two months after a large earthquake. That blast scattered ash and cinders as far as Tokyo, 60 miles from the volcano. Last year's earthquake and Fukushima nuclear crisis were unparalleled disasters, but people in and around Shizuoka Prefecture fear the ultimate catastrophe — the eruption of Mount Fuji — may be looming. Experts at Japan's National Research Institute for Earth Science and Disaster Prevention say there is heightened pressure under Mount Fuji due to last year's devastating earthquake and aftershocks. It is feared the increase in pressure could trigger an eruption. When Mount Fuji last erupted, the pressure caused by the prior earthquake was weaker than that of last year, the researchers said. In May a team of researchers warned that the mountain may collapse if a newly-discovered fault-line underneath it shifts. Based on the tectonic movements caused by the magnitude 9.0 quake that struck March 2011 and the magnitude 6.4 quake that followed four days later, the researchers estimate that about 1.6 megapascals of pressure were placed on the magma chamber, which is thought to be some 15 km underground. That's equivalent to an atmospheric pressure of some 15.8 kg per sq. cm. In the past, 0.1 to several megapascals of pressure have been enough to trigger volcanic eruptions, including at Mount Fuji, it said. Although conditions in the magma chamber vary, 1.6 megapascals is "not a small figure," said Eisuke Fujita, a senior researcher at the institute. A 2004 Japanese government report estimated that an eruption would cost the country over $30 billion US dollars. A new study is focusing on the potential damage that would be caused by a series of simultaneous earthquakes along the Nankai Trough, where it is feared another earthquake will soon take place. The most recent models have revealed that, in the worst-case scenario, 323,000 people would die and the tremors could trigger an eruption at Mount Fuji. The huge quake of March 11, 2011 and tsunami that it generated devastated a large area of the country's northeast, killing around 19,000 people and generating the nuclear emergency at Fukushima.

pie-eater 207 Posted September 11, 2012 Share Posted September 11, 2012 Based on the tectonic movements caused by the magnitude 9.0 quake that struck March 2011 and the magnitude 6.4 quake that followed four days later, the researchers estimate that about 1.6 megapascals of pressure were placed on the magma chamber, which is thought to be some 15 km underground. I have been putting some careful thought to this issue over the last few minutes and wondering why they don't mine down to this 'magma chamber' and put a big pipe in there so that this magma could be released and brought up to be deposited safely into the sea. Obviously the pipe would need to be very long and pretty heat resistant. Teflon perhaps, wouldn't stick either - though I'm no expert of magma (is it sticky?) Or, perhaps put a giant dome over Mount Fuji. It would have to be quite thick though, one would imagine. If Fuji blew, it would make some spectacular "spattering" effects within the dome whilst keeping neighbourhood areas safe. There would be lots of publicity for Japan. As we know, there's no such thing as bad publicity! And just think, while Fuji was now erupting, people could walk over the top of the mountain and look down. It would be quite spectacular.

pie-eater 207 Posted September 11, 2012 Share Posted September 11, 2012 Well each problem is case by case of course, but I do believe the dome solution to be relevant here. Link to post Share on other sites
tokabochi 9 Posted October 17, 2012 Share Posted October 17, 2012 Had a series of shakes here since late last night, strongest one Shindo 4, all centred Tokamachi. Anothere a few minutes ago. Link to post Share on other sites
muikabochi 208 Posted October 18, 2012 Share Posted October 18, 2012 All ok over there? Looks like over 10 since last night. I probably felt about 5 of those here, the one around midnight was a shindo 2-3 here. A nasty reminder, couldn't get to sleep until after 2. Link to post Share on other sites
joshnii 2 Posted October 18, 2012 Share Posted October 18, 2012 Haven't felt any of those looks like it is localised around Tokamachi and the surroundings. "Aftershock" of last year? What's the cut off time for one to be called an aftershock? Link to post Share on other sites
tokabochi 9 Posted October 18, 2012 Share Posted October 18, 2012 Don't know. I think I would feel better if it was classed as an aftershock and not something 'new'. Though I totally dont understand it all. Just had another short while ago. Link to post Share on other sites
