Near the damaged nuke ... too early for details.

Tectonic Summary
The October 25, 2013 M 7.1 earthquake offshore of Honshu, Japan occurred as the result of normal faulting in the shallow oceanic crust of the Pacific plate. The earthquake occurred outboard (east) of the Japan Trench, which marks the seafloor expression of the subduction zone plate boundary between the Pacific and North America plates, and is immediately up-dip of the source region of the March 2011 M 9.0 Tohoku earthquake. At the latitude of this earthquake, the Pacific plate moves westwards with respect to the North America plate at a rate of 83 mm/yr before subducting beneath the island of Honshu. Note that some authors divide this region into several microplates that together define the relative motions between the larger Pacific, North America and Eurasia plates; these include the Okhotsk and Amur microplates that are respectively part of North America and Eurasia.
The location, depth, and focal mechanism of the October 25 2013 event are consistent with normal faulting rupture near the outer-arc high of the Japan Trench. In this region, normal faulting is encouraged by both the bending of the Pacific plate as it enters the subduction zone, and by stresses transferred from the locked subduction thrust interface to the west. Since the March 2011 Tohoku earthquake, two large events of M 7.7 and M 7.3 have occurred in the vicinity of the October 25, 2013 earthquake. The M 7.7 event, on March 11, 2011, was also a normal faulting event near the outer-arc high and occurred 95 km north of the October 25 event. The M 7.3 event, on December 7, 2012, was a more complex earthquake resulting from thrust motion near the trench 100 km to the northwest of the October 25 earthquake. Since March 2011, 10 additional events, ranging in magnitude from M 6.1-6.4, have occurred in this region east of the Japan Trench.

Only 10 km down, tsunami ???
There has been a 5.1 after shock

Thanks ...
Fwiw ... prior to my OP there where many from *another place* putting their powers to be to create a bubble to protect the reactor.
Always another layer to a story yes???

I expect old news by now ... but offering more data.

It seems not as bad as they try to portray it
Yet another large earthquake signaled the arrival of a geomagnetic storm, bringing more evidence that the two might be linked.
102513aThe magnitude 7.3 earthquake struck offshore Japan, east of the mainland at 10:00am Pacific and 1pm Easter Time. The quake was felt mildly across Japan. The distance from the epicenter was 325km (202mi) ESE of Ishinomaki, Japan and 475km (295mi) ENE of Tokyo, Japan. Generally this distance would be a gentle rocking. The quake struck nearly the same fault area as the quake that brought down the Fukushima Nuclear Power Plant.
TheWeatherSpace.com Senior Meteorologist Kevin Martin has been watching solar storm and quake influences since 1999, noting that increased geomagnetic storms bring increased quakes across the world.
“These quakes are not a coincidence,” said Martin. “These quakes … have triggers … and one such trigger for quakes seems to be strong solar storms, which bring geomagnetic storms to the planet.”
So where is this geomagnetic storm? Kp-Index was zero this morning and now it is a two. With M and X class flares from the Sun being detected, that means it is rising and it should arrive today. Forecasters expect a geomagnetic storm so skywatchers in the upper latitudes should be on the lookout for aurora.
The Tsunami Warning Center issued a statement saying that based on data, a destructive tsunami is not likely from this event. However, the Japan Meteorological Society issued a Tsunami Warning, countering NOAA’s decision.
