7.3 Earthquake in Miyagi Prefecture - Is this a Precursor for a larger quake ?

http://fukushima-diary.com/2012/12/column-5-lessons-learnt-from-m7-3-of-1272012/


[Column] 5 Lessons learnt from M7.3 of 12/7/2012


M7.3 and the series of aftershocks hit coastal area of North Japan. According to Japan meteorological agency, it was not the end, it hasn’t even begun yet. They expect M8.0 to come. [Link]
Major aftershock was promised to occur since the moment of 311. The question is not if it happens, it’s when it happens.
The M7.3 gave us some lessons. If we still have time before M8.0, there’s no way to miss the lessons learnt.
1. Phone line is down
From the very beginning of M7.3 (It was a long earthquake just like 311), the phone line went down. You can’t take a contact with your family, friend, or even police. The more severe it is, the more likely it goes dead. However, LINE was available this time.
2. Website is down
Just after the shake, I tried to check the English page of Japan Meteorological Agency but it retuned “503″ error, unavailable. Only the Japanese page could be loaded but it was still slow and I couldn’t load the image of map. The only available site was Yahoo (http://typhoon.yahoo.co.jp/weather/jp/earthquake/) but considering most of the domestic sites went down in 311, you can’t really count on it. It’s better to think you can’t get accurate information when it’s truly severe.
3. Transportation is down
About one hour after M7.3, heavy traffic jams were observed in Fukushima prefecture. Most of them queued for gas station, but in the potential aftershock hits Tokyo, it would be way worse than that. Streets are narrow, ways to go to western Japan are very limited, and the population is 7 times bigger than entire Fukushima population.
It wasn’t only the traffic. Sendai airport was shut down for 3 hours after M7.3 for the risk of Tsunami.
The main airport of Tokyo is Narita airport, but it takes 1.5 hours by car (without traffic jam) and it takes 1.5 ~ 2 hours by train (if train still works) from Shinjuku station of Tokyo.
The risk of SFP4 is warned, but if it falls down, there would be no way to get out of Tokyo area.
4. Monitoring post is down
Immediately after M7.3, the monitoring post of Tokai Daini nuclear plant located in Ibaraki went under maintenance. [Link] It hasn’t been updated since 16:10 of 12/7/2012. The website says it’s under maintenance from 12/7 to 12/10. Considering the fact that Japanese government concealed SPEEDI to avoid “panic” in 311, it is highly likely that they get monitoring posts under instant maintenance when it detects rapid increase of radiation level etc.. You can not count on public monitoring post.
5. The only source would be Tepco
After M7.3, everyone including Japanese government had to reply on Tepco for the information of Fukushima plant. Because the plant is isolated and the radiation level is extremely high, there are no media, journalists or governmental agencies to stay keep us informed. Tepco is the only one to know the actual state. M7.3 proved this situation has never been improved since 311. Tepco announced Fukushima plant stayed sound, but it was another lie of them, they actually discharged the air to decrease the air pressure of the reactor1 building in Fukushima Daini. [Link] They haven’t even explained the reason of the accident. No one can trust Tepco, but Tepco is the only source of all the information.
An anonymous source from the inside of the government tweeted like this below,

After all, the only thing MEXT or METI could do is just trying to be patient to wait for Tepco to update the information. They can take all the Tepco lies seriously and announce it to the people. The crippled system has never been changed.
<End>
What should we do ?
The ideal solution is to start moving to the west by taking advantage of this weekend. However, it might not be easy for most of the people.These are some tips about the “start up” from what I experienced and heard.
1. Soon as it stops shaking, charge your mobile phone and check Facebook or Twitter. They don’t have the servers in Japan. They don’t get down.
2. Get your wallet, IDs and coat close to you.
3. Use your intuition and image what is happening, and where.
4. Go to the west by using the fastest way. You’d probably have to walk on the way, but that’s still better.
I really hope nobody, none of the animals die from the potential crisis.

[Column] Significant similarity between M7.3 of 12/7/2012 and M7.3 of 3/9/2011

At 17:18 of 12/7/2012, M7.3 hit “Off the coast of Sanriku” and aftershock keeps occurring.
This seismic situation is significantly similar to 3/9/2011, 2 days before 311.
At 11:45:12 of 3/9/2011, M7.3 hit the same location with series of aftershock to follow.

The only difference is the fact that the earthquake on 3/9/2011 was reverse fault type, but the one on 12/7/2012 was normal fault type. [Link 1 2]

It might be presumed that the plate that ran aground on 3/11/2011 was stretched over again on 12/7/2012.
We need to be cautious for the following few days. If I were in Japan, I would move to somewhere west where you can easily access an international airport during this weekend.

(UPDATED) M.7.3 Earthquake in Tohoku, 1-Meter Tsunami Arrived in Miyagi Prefecture (Ishinomaki)


Just saw the headline at Jiji Tsushin.
7日午後5時18分ごろ、東北から関東にかけて強い地震があり、青森、岩手、宮城、茨城、栃木各県で震度5弱の揺れを観測した。気象庁は、宮城県に同5時40分に高さ約1メートルの津波が到達する恐れがあるとして津波警報を出した。

Strong earthquake at 5:18PM on December 7 in Tohoku and Kanto. Aomori, Iwate, Miyagi, Tochigi had the seismic intensity of "5 weak". Japan Meteorological Agency has issued a tsunami warning to Miyagi, as 1-meter high tsunami may arrive at 5:40PM.

Prime Minister Noda, who was campaigning, returned to the Official Residence on the news.

It was a Magnitude 7.3 earthquake.

Nuclear Regulatory Authority says there has been no report of problems at nuclear power plants.

TEPCO says there is no damage to Fukushima I Nuclear Power Plant. (As if the plant needs any more damage..) No one was hurt, no change in plant parameters. TEPCO says it was 4 in seismic intensity in Hamadori (ocean 1/3 of Fukushima Prefecture where the plant is located).

NHK apparently changed its way to report on the tsunami. The announcers are using strong words to appeal to people to take heed and take refuge. Asahi Shinbun quickly reports that a male NHK announcer is saying:
"Tsunami Warning for Miyagi Prefecture... In 10 more minutes... Please recall how it was in East Japan Great Earthquake [March 11, 2011 earthquake]... Escape to highest places as possible... To save lives, hurry and escape..."

NHK says the 1-meter tsunami did arrive at Ayukawa in Ishinomaki City in Miyagi at 6:02PM.USGS site shows a relatively strong aftershock (M.6.2) about 13 minutes after the M.7.3 quake, then a M.5.5 and M.4.7 (two).

Many Japanese on Twitter are recalling how it was in March last year. Not the March 11 one but the one that came before, a few days earlier, just about the same magnitude.

Tsunami hits Japan’s Miyagi prefecture after powerful 7.3 quake

Following a 7.3-magnitude quake, a meter-high tsunami struck Japan’s Miyagi prefecture, where the tsunami that triggered the Fukushima nuclear plant crisis hit last year. Authorities reported no damage, radiation levels at Fukushima remain stable.
The earthquake hit 245 kilometers off Japan’s eastern coast at a depth of around 35 kilometers. The tremor prompted a tsunami warning on the Miyagi prefecture, where last year’s devastating quake triggered a tsunami and multiple meltdowns at the Fukushima Daiichi nuclear plant.
The tsunami warning has now been lifted and five people have been taken to hospital in the Miyagi Prefecture with minor injuries.
The US Geological Survey initially put the quake’s strength at 7.4-magnitude, but later revised its estimation, lowering it to 7.3.
An aftershock of 6.2-magnitude struck the eastern coast just minutes after the initial quake.
Japanese media reported how buildings in Tokyo swayed in the ensuing tremors.
Following the tsunami warning, local authorities advised some residents of Miyagi prefecture to evacuate their homes.
A news presenter on Japanese state news channel NHK repeatedly told citizens to flee to safety during live broadcasts. 
"Remember last year's quake and tsunami, call on your neighbors and flee to higher ground now!" he said.
In the neighboring prefecture of Fukushima, officials were quick to report that the Daiichi nuclear plant remained stable following the earthquake. 
"All workers were ordered to take shelter inside buildings at the Fukushima plant. No abnormalities were confirmed with the radiation monitoring posts at the Fukushima plant. No abnormalities were seen with the water processing facilities,” Tokyo Electric Power Company said in a statement. 
In March of last year, the Daiichi plant at Fukushima was the scene of the worst nuclear disaster since the Chernobyl tragedy in 1986. A 9.0-magnitude quake triggered a massive tsunami, causing damage to the plant that led to multiple meltdowns. Over 15,000 people died and more than 3,200 people went missing. 
Radiation levels in Fukushima remain high, contaminating food and water in the area.
