One observation today - the Tokyo Bay was oddly choppy today, almost like when there's a low pressure system in the winter, but today we're under high pressure with very low wind, maybe 5kt this morning when I first noticed it. It didn't fit. And I've been watching the water in this bay pretty much every day for close to four years, so I'm pretty attuned to it.

We just went for a walk and it was the same. Choppy. And this was before the little 5.2 that hit just a while ago.

OK, this is a stretch, but could ocean floor energy release, even perhaps micro, very small movements, immeasurable movements, cause this? Or even no movement, but energy release of another variety? Something is causing this choppy water.

EDIT: Before the 7.1 yesterday, the water was smooth, very smooth and calm.
