lol, you guys keep talking about the quake map, and I keep trying to tell you that you are only seeing those quakes above 4.5. It does not represent the full seismicity going on in Japan, and especially not (relative to this thread), in the southern subduction zone.
So in pursuit of better maps that show it all, I wrote to the JMA and received information that led me to find this:
And this is just since 3/16, and doesn't even show the bigger ones we already know about. And it only shows those 3.0 and above. There are even more microquakes going on beyond this! But that is a bit clearer a picture since 3/16.
And there you can see the swarms I was talking about, as well as all the activity directly around the southern subduction zone. It is more active than people know. And so now you know.

Is this quake along the fault in question?
Major earthquakes like the Sendai M9.1 earthquake, create massive stress transfer and may inadvertantly trigger other earthquakes on other faults or volcanoes. This may be the case in Japan this time.

I think Tokyo ought to be evacuated. Period.
