Oct 25, 2013 – Central Northern Utah, USA- DISCLAIMER
Felt as far away as Tokyo, a 6.8M, upgraded to a 7.3M quake, and later downgraded to a 7.1, just hit today off the Fukushima Coast. I just noticed it due to increased blog traffic to an old blogpost (this one from Dec 7, 2012, which includes some additional info links as well), when a 7.3 also unleashed a small 1 meter tsunami and had lots of people take a closer look at the extremely troubled Fukushima-Daiichi NPP (Nuclear Power Plant complex).
Today’s view of latest Earthquakes in the area (data: USGS):
For checking on radiation levels and getting clues on possible nuclear infrastructure damage, see further below. First, excuse me for parroting some basics as well.
- !–> For the latest News, see HERE.
The following ‘Tsunami Advisory’ (not even a warning) predicted a 1 meter tsunami wave, but it didn’t materialize beyond 30 centimeters and the advisory has been cancelled (at posting time). Check the latest at the source:
Ex-SKF News had the following [some emphasis and update order is mine]:
- […] See Full blogpost at Ex-SKF (Oct 25, 2013)
- (UPDATE 4) 30-centimeter high tsunami in Ayukawa, Miyagi Prefecture observed at 3:07AM.
- (UPDATE 5) Workers at the plant are safely inside the Anti-Seismic Building on site, says NHK. (It is NOT that they were evacuated from the plant.) The workers were working near the seawall at 2 in the morning injecting water glass into the soil to build the impermeable wall in the soil to prevent the groundwater from leaking into the plant harbor. Yes, that same operation which actually caused the groundwater to rise and go over the wall. Ugh.
- This, on top of heavy rain due to Typhoon No.27. It is raining in Fukushima and wide areas in Kanto and Tohoku. According to JMA, “Heavy rain and gale” advisories have been issued for Fukushima, and “heavy rain and flood” warnings have been issued in Kanto.
- (UPDATE 6) It seems the municipalities in Miyagi, Iwate (prefectures north of Fukushima) are playing it extremely safe, in light of the March 11, 2011 earthquake/tsunami. A number of municipalities that suffered grave damages in 2011 are issuing the evacuation recommendations to the residents in coastal areas. They include: Rikuzentakata (Iwate), Ofunato (Iwate), Ishinomaki (Miyagi), Higashimatsushima (Miyagi).
- (UPDATE 7) Japan’s Nuclear Regulation Authority says there is no damage/problem reported at nuclear power plants in Tohoku (Higashidori, Onagawa, Fukushima I and II) and Kanto (Tokai II). […]

And ENEnews (Energy News) had the following highlighted [excerpt]:
- USGS, Oct. 25, 2013: The October 25, 2013 M 7.3 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. […] 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. […]

–> A quick look at the TEPCO Fukushima Webcam (or, alternate, straight from TEPCO: http://www.tepco.co.jp/nu/f1-np/camera/index-j.html) showed that it was rainy and windy, and clearly shaking for about a minute.

Damage at plant? Radiation released??
That is always the hard question. I’m sure if anything is revealed, one of these dedicated news reporting sources will more than likely report on it as soon as they find out about it.
Before anything else, first thing I’d check is which way the wind is blowing.
!–> For checking on Weather data, I go to my own ‘METEO‘ page for that, where I added a whole section for info on Japan. Among the many options, I just checked these:
- JMA – Fukushima map (click on Namie for most similar weather as F1 NPP. The nuclear disaster site is just 6 miles to the south on the beach, See Google Maps)
- Intellicast Japan
- Japan Meteorological Service – Wind
- Surf Forecast Japan
It seems that since a couple hours ago (early morning in Japan on what is already Oct 26, 2013), the Wind has turned a bit from NW to NNW at the Fukushima-Daiichi NPP, and further south NNE, NE or even (local erratic patterns?) East at times. So, in this case, the wind is blowing mainly out to sea, as usual, with a possibility to make landfall as the storm moves and swirls the air around. (Could be interesting to monitor West Coast rainfal in coming weeks… Have a look at my compilation of significant evidence of continued fallout in rain in the USA).
-> So IF radiation leaking has suddenly increased into the air, it’s unlikely to get picked up by the monitoring network on land, except for perhaps by the beaches to the south of the Fukushima Coast.
As I see it, the only place worth checking in this particular case (right now) would be on the coast near the troubled site and a bit further to the south in the Ibaraki Prefecture, which may still be able to pick up something (as wind direction there also went NNE in parts of Ibaraki…). Let’s see…
!–> For checking on radiation levels, I go to my NUCLEAR page, which has a tab for various Online Radiation Monitoring options worldwide, where I pick the link to my JAPAN radiation monitoring page. There, I have again many options… To pick just a few…
If you speak Japanese, explore the radiation monitors at http://ma-04x.net/all.html. My own looking around there did not reveal anything unusual, beyond the obvious elevated and heavily fluctuating levels seen in that part of Japan nowadays.
I check at SPEEDI, which lists the following levels for the Fukushima Prefecture:
“Under Survey” is often nuclear industry code for “Censored”, so I’m curious where precisely these locations are… Of course, ‘very TEPCO’: no data from monitors surrounding the Fukushima-Daiichi Nuclear Disaster Site, on the coast line:
And the Following for the Ibaraki Prefecture just south of Fukushima:
The above readings may serve as a reference in the next day or so. I may not update this unless I discover something not yet reported elsewhere.
At the monitoring station in Hino, Tokyo, all looks within “new-normal” levels, at time of posting as well:
Oct 26, 2013 UPDATE:
– No apparent inland signs or reports of significant additional nuclear infrastructure damage. Water tanks on site are reportedly full, some contaminated water was released due to heavy rains from Typhoon.
– Some aftershocks, so far nothing unusual:
– One of the 6 “Under Survey” stations came back online. It’s the station most upwind from the plant (“C” in the annotated Fukushima map, above): 3.6 µSv/hr. At 2:43 pm Mountain Time (USA), it’s measurement was:
|Shinzan Futaba Town||3616|
Note: “Radiation Dose” (such as expressed in rem, Sievert or Curie) is a unit used to deceive, with its health danger scale “calibrated” to doses from external sources (cosmic rays, X-rays, CAT-scans, and such). Industry can be quick to point out that 3.6 µSv/h may seem like nothing when compared to natural background levels found at higher altitudes (or on airplane flights), but these are actually, when honesty matters, not comparable, as radiation dose is logarithmic and inverse with distance from the emitting source. While the dose in the air is overall low, the cells that would be in direct contact with the radioisotopes, if what’s in the air gets inhaled or ingested, would get a full-blast thousands of times higher. You can demonstrate this easily with a Geiger Counter and the 37 kBq of Am-241 in a standard smoke detector. Even right near it, you won’t measure much difference with background, until you put the Geiger Counter smack on it, then you could see measurements over 100 µSv/hr. The body can repair an amazing amount of radiation cell damage, but continued internal exposure from radioactive particles inside the body is known to cause numerous health problems to many people especially years later. See also info on my Health Exposure Effects page.
– Radiation in Tokyo saw an apparent “radioactive cloud whiff”, causing a brief spike to double normal radiation level:

I hope this is somehow helpful. Comments and Tips welcome. Peace.
