well actually, the last few days a lot of tension has been released.
129,162 TTNT (tonnes of TNT) in the Santa Cruz Islands
239,036 TTNT in Hokkaido
alone

Does anyone know how close to the Fukushima Daichi nuclear plant this quake is. A 6.9 is starting to get big enough to finish off one or more of the buildings there if it struck close and shallow enough. That would raise the level of that disaster by orders of magnitude if it happened.

approx.600km
I could have told you exactly if I had the co-ordinates of the Plant,
and EMSC are probably wrong with the quake epi-centre as well

as per the link on the previous page
www.jma.go.jp...
Fukushima-ken Nakadori - JMA Intensity 3
Felt by most to all people indoors. Some people are frightened.
Objects inside rattle noticeably and can fall off tables.
Electric wires swing slightly. People can feel it outdoors.

All these six pointers in the Solomons have me thinking 6 is the new 4 LoL they just keep coming has me sitting in Vancouver double checking my B.O.B and making sure lights and stuff are charged, the earth she's angry it seems

And that would be quite disturbing. However, I am almost totally convinced that this is a not so classic foreshock sequence.

I think there will be an 7.8-8.6, with big waves in the very near future

I will be overjoyed if I am mistaken!!

Nowhere near (615 km). Hokkaido is the island above the main one.

@Muzzy: Apologies did not see your post

Co-ordinates are: 37.421175 N, 141.020518 E

Like I said, the Pacific plate is turning. The bend around Santa Cruz is opening, Japan in compression. South America is joining in as the whole thing gets a shove including the Mid Pacific Ridge. Just look at recent locations including Alaska and it all fits.

Except they are not in the Solomans, they are Santa Cruz and the trench does a big turn right there.

Alaska started it all with the 7.5

ETA: The Solomans may come yet if that part is twisting down against the Australian plate as that tries to push it up and out of the way.

The Santa Cruz Feb 1 2013, 22:16 UTC event was not a 6.7 but a doublet, the 2nd at 22:18 UTC

6.3/6.3(GFZ) 6.3/6.4(USGS) or 6.4/6.4(GCMT) - all Mw

Would it be sensible to assume we should see an anti-clockwise pattern around the Pacific plate for any larger earthquake groupings over the course of the year?
I'm also wondering about the pressure on that little corner up by Kamchatka up there, that area's put out some high mag doozies in the past. Could the pressure and stresses from that rotation bottleneck up around there until the proverbial cork goes?

And another question would be "how close was this to Higashadori, Tomari, or the Rokkasho [mox] Reprocessing Plant ?"

I am confused, the Santa Cruz Islands are part of the Solomons... what do you mean by saying they are not in the solomons.... I don't get it. Even USGS has them always listed as Solomons.

Geographically/Politically or Geologically?

Santa Cruz Islands are geologically more a part of Vanuatu IMO. Bismark and Soloman are seismic region 15 and Vanuatu/SantaCruz are seismic region 14.

Even USGS has them always listed as Solomons.

Where?

Some data for Santa Cruz BTW. Equivalents of the output of the last 7 days.

reply to post by aLLeKs

The Santa Cruz islands are politically part of the Solomon Islands, but geographically and geologically they are an extention of Vanuatu (the New Hebrides Is)
Don't you read my posts?I mentioned all that last page.

@ Puterman, touche, you type faster I guess

He means the new layout, USGS scrapped the Flinn-Engdahl regions for the new layout.

Only the moment tensors still have the old F-E names.

Now it became XX km ZZZ of [city name here]

The 6.4 22:18 doublet as example earthquake.usgs.gov/earthquakes/eventpage/usc000ezw4

M6.4 - 67km SW of Lata, Solomon Islands 2013-02-01 22:18:35 UTC

so delete the 6.4 and replace with to 6.3's makes that 154,130 TTNT for Santa Cruz Is ,
still falls well short of Hokkaido's single 6.8 and minor aftershocks at 239,036 TTNT though.
BTW: All my Santa Cruz calc's are based on GFZ data.

reply to post by wujotvowujotvowujotvo

Ah ha.
Well there's another reason not to bother using USGS
It confuses people

reply to post by wujotvowujotvowujotvo


Oh, OK. I almost never look at that one.

The 7 day text file still comes through with the FE Regions.

Last report from Kyodo
------------------
00:52 3 February
Magnitude 6.4 quake hits Japan's Hokkaido, but no serious damage

SAPPORO, Feb. 3, Kyodo

english.kyodonews.jp/news/2013/02/207383.html

An earthquake with a preliminary magnitude of 6.4 struck Japan's northernmost prefecture of Hokkaido late Saturday, leading to highway closures and causing blackouts in some areas, but there were no reports of serious damage or nuclear power plant irregularities, the weather agency and local official said.

The epicenter of the 11:17 p.m. quake was the central part of the Tokachi region in Hokkaido, at a depth of about 120 kilometers, according to Japan Meteorological Agency.

The U.S. Geological Survey said the quake measured magnitude 6.9.

The quake registered upper 5 on the Japanese seismic intensity scale of 7 in Kushiro Akan Chuo, Nemuro Attoko and Urahoro in the eastern part of Hokkaido, and lower 5 in Obihiro and other parts of the prefecture, according to the agency.

Some injuries have been reported. A woman in Obihiro sustained a cut on her leg with glass believed to have been broken in the wake of the quake, according to local fire department officials.

Hokkaido Electric Power Co. said there have been no abnormalities at its nuclear power plant in the village of Tomari in southwestern Hokkaido.

Tohoku Electric Power Co. said no irregularities have been found at its nuclear power plant in the village of Higashidori, Aomori Prefecture.

Japan Nuclear Fuel Ltd. also said there have been no problems at its nuclear fuel reprocessing facility in the village of Rokkasho, Aomori Prefecture.

Thank you very much for clearifying this... now I understand.
