This popped up on the Japan Meteorological Agency site when I visited. I've never checked this page out before so I don't know if this level of activity is greater than normal, but it sure looks like there's a lot going on. http://www.jma.go.jp/en/volcano/map_0.html

It looks like 'the year of the volcano' - so I guess there's a good chance it will pop

Planning to grab your deck-chair and a six-pack and going to check it out?

Meanwhile there is a lot of activity coming from an area in Nantou over the last 48 hrs - so far the biggest has been a 5M this morning - but that's a place where 'the big one' could easily happen
