If I’d known Norikura was a potentially active volcano I would have never taken my family camping up there.
I would have let them go by themselves.
What does “potentially active” even
mean? Norikura’s highest peak, Ken-ga-mine, was formed by a volcanic eruption
9,600 years ago (as of last Tuesday). It was somewhat reformed in a second big
burp 400 years later. Ebisu-dake, a bit to the north, is said to be the child
of an eruption from 2,000 years ago.
Going by the math we’ve got another five millennia of dormancy to enjoy. But some wise guy loses his calculator and starts making wild claims on Wikipedia and there I am lying awake all night in the tent.
Not that I ever get much sleep in a plastic 7’ x 7’ dome with three kids and a snoring wife.
