Honshu had a M7 two days earlier.
From statistics there is about a 5% on one magnitude larger event
happening within a week.
Perhaps there might be something distinctive about this foreshock that
could be helpful in forecasting.

Quite reasonable are you now! Last year, June, 29th 09.15, I had
sayed that a circle of 65Km is useful, and of course, the site was
really active, also before the foreshock !! More active than any
place in Japan, we can analize that.
But, what is your opinion on the hiper clusterization?. See my recent
post on 52 events 6+ in 30 days...

65 Km is 5/8ths of a degree about the spread of most aftershocks in a
series.

Aftershock, foreshock..
Bull. They all have causes.

Putting the cart before the horse will still get some power to the
vehicle. The clustering must be taking place becase the sound that
couses it is getting there. The only delivery system I can imagine is
a planetary wave. There must be a channel running from the Norwegian
Sea to the seas around Japan.

There is a distinctly long lived Low near Jan mayen Island. Look at
pdfs of rossby waves and notice how they devolve over 120 degrees.
Something like that is going on via the skies.

Or I am a little tea pot.

we've got it with the birds but Texans and esp Texas law enforcement,
Texas organized crime are not with it and exerting continuous pressure
to abort. One group LE asked state workers for loudspeaker to thwart
the bird recordings.

Nice pincer uplift to the New Madrid this morning.
