Mmm... one evening, a long time ago, my ancient mother-in-law suddenly sat bolt upright in her futon and uttered the one terrifying word Jishin (Earthquake).* Five seconds later the earthquake hit. Could be (an I'm inclined to think it probable) that because she was lying down on the floor and half asleep she was probably more sensitive to a subterranean disturbance than the rest of us who were still sitting around chatting.

But I also seem to remember reading somewhere that early, and very simple crop circles (not the fancy stuff you see on calendars and postcards now), were sometimes observed at geologically 'sensitive' points.

Just a thought - perhaps it all ties in somewhere.

* Interestingly, jishin in Japanese not only means earthquake, it also means 1) a magnetic needle and 2) the hour hand.
