The Final Warning to Tokyo

Uh oh, quake hitting near Tokyo?...(Seeing it in GEE) Looks in the 6 range. Standby, update in a few when it posts to JMA and/or USGS.

6.8, and near Fukushima? Man! Not good!


USGS: 6.5, right near Fukushima

Chances of big quake below Tokyo rising

The possibility of a huge plate-boundary earthquake amplified by simultaneous moves in two or more focal areas beneath Tokyo has been increasing since the Great East Japan Earthquake, according to the University of Tokyo's Earthquake Research Institute. The institute said that since the March 11 disaster, pressure on the tectonic plates beneath the city has changed and two or more focal areas may move simultaneously, resulting in a massive quake. The institute intends to continue monitoring and assess the possibility of a huge earthquake. The tectonic makeup of Tokyo and surrounding areas is complicated, with two ocean plates subducting below a land plate on which the Japanese archipelago is located.

There have been many earthquakes in this area, as both plate-boundary quakes, which are caused by friction between the plates, and inland quakes, which are caused by faults in the plates, can occur. The average number of quakes measured at magnitude 3 or more in the five years preceding the March 11 disaster was about eight a month. The institute discovered that the number of small-scale plate-boundary quakes that are not felt by people has drastically increased following the March 11 earthquake.

Also, the preliminary observed number of magnitude-3 or larger plate-boundary quakes between March 11 and Aug. 20 rose about fourfold in an area 60 to 70 kilometers below northern Tokyo Bay. Similarly sized plate-boundary quakes occurring 40 to 55 kilometers below southern Ibaraki Prefecture have increased about 20-fold. The number of inland quakes has not drastically increased, but the institute said the types of the quakes have clearly changed. There have been huge quakes with shallow focal points below Tokyo and surrounding areas in the past. The 1923 magnitude-8 Great Kanto Earthquake occurred in southern Tokyo Bay.

It sounds terrifying!
Can't you leave?

with that 60 trillion yen.
they could have build small towns in other places.
that would not suffer as much from a quake.
it would take as long.

this earth quake site.
quakes.globalincidentmap.com...
is only showing some of the quacks?
but it shows Lots in us and alaska.
what other sites are good for quick maps?

Questions to True American and Zorgon:


Now, since the big one in March we`ve had constant tremors, mainly in Fukushima, and actually, a number in every region in Japan - even way up north, past Hokkaido, near Kunashir....sometimes we`d feel the stronger ones in Tokyo, sometimes not but the EQ alert on my phone was ringing almost constantly.

Human 0815 posted that article from Yomiuri, a nation wide `reliable` source which mentions a heightened probability of an EQ hitting the Tokai region. Some Japanese friends told me today that it was even on the news (no source, no proof - just what I`ve been told).


Now, lately, there have been fewer tremors than usual, my phone doesn`t ring as much....and actually on Sept 1, we`ve only had 1 nationwide - off the coast of Ibaraki (they are increasing in this area by the way)
One whole day with only 1 EQ....weird....

quake.twiple.jp...

Is something brewing?
Some people say that small and regular EQs are good actually, because they release energy.....

What are your opinions on this?

I`ve also heard a theory whereby buildings built on reclaimed land can sometimes be safer than those built on rock....??! Really??!

There is something brewing up but it seams like not directly in Tokyo/ Kanagawa!
Yesterday afair NHK and JNN reported about the Nankai Faultline and a Tsunami Hit
of Nagoya, Osaka and places in Shikoku!

They found a new way of calculation because of the Tohoku-Quake
and estimated that the Tsunami will be very high
and that the protective Measurements like Sea-Walls will sink down
because they build on Sand!

Nagoya is build in the Mouth of 3 big Rivers and the Town itself is on Sealevel.
Try to search it via the Tube or U-Stream!

PS: Our Earthquake Device is configured on Mag. 4 in a specific Place (our House)
otherwise you will be scared Non-Stop

Don't know if anyone has posted these, apologies if so, thought it might be interesting to see...

Interesting to see from the outside...
Not so much fun when you`re inside one of them!!!

I can only imagine, having worked on the 72nd floor of a large building in Toronto during a violent windstorm where the building was swaying 4 ft to either side, it is a sickening feeling. Architects build a flexible tolerance in skyscrapers, usually up to 6ft (sometimes more if earthquake designed), but the impact on occupants is very alarming -- especially when seeing things slide back and forth on your desk and trying to work while your chair is rolling around.

We probably were only meant to be above the ground as high as a tall tree....from an evolutionary perspective all of our 'flight' responses need to be suppressed.

The sale of Flats in High Rise Buildings has had nearly collapsed since 03/11

Some of the People had huge Problems because the Elevators stopped,
no way to go more than 20 Kai when you are old, no water and no food

Everybody had HUGE problems because ALL the elevators stopped. After a quake with the magnitude like we had in March...they all stopped.

Now, I think it`s just a matter of time...
Here, people will soon forget, trust the buildings and continue buying...

But it is a big difference when you live in the 20'th Floor or on the 40-60'th Floor.

The interesting Point is that Mr. Mori, who own all High Rise in Tokyo incl. Roppongi Hills,
Ark Hills and Midnight Town said that he will not build real High Rise anymore because of
the psychological Stress!

Lately i saw a Reportage from Odaiba and some other parts where they had the huge
Ground Movements, some Houses looked like they need to tear down (?) Tear apart (?)

I am in one of the typical Houses from the '80,
Basement and one Floor with a Garden in front.

But our House is build on Swamp,
i saw this in a Government File where they collect all the geological readings!

Floodgates in Tokyo fail tsunami's test

A tsunami warning was issued at 3:30 p.m. on March 11, as the Meteorological Agency forecast that tsunami measuring a maximum of two meters in height could strike the Tokyo Bay coast.

The ministry and Tokyo government subsequently decided to close 39 floodgates on the Arakawa, Tamagawa and other rivers and six seawall gates on the Tokyo Bay coast. Immediately after the decision, 33 floodgates were closed by remote control, the officials said. Facilities that have to be operated manually, however, have been entrusted to private-sector companies, and officials were unable to contact them by telephone after the massive earthquake.

Government officials tried to rush by motor vehicle to those floodgates and seawall gates but could not get there due to traffic jams, they said. The first tsunami wave arrived on the Tokyo Bay coast at 4:40 p.m., but two floodgates at Haneda and Minami-Rokugo along the Tamagawa river in Ota Ward were left open until 25 minutes later, according to the officials. Both these gates are under the central government's jurisdiction. Four seawall gates handled by the Tokyo metropolitan government in Koto Ward and Minato Ward were closed by Tokyo government officials about 30 minutes after the first tsunami wave. The officials managed to do the job of companies that were commissioned to handle the facilities but did not due to lack of telephone communication, the officials said.

The first wave to reach Tokyo Bay was about 80 centimeters high. The highest was 1.5 meters and came at 7:16 p.m.

Thanks for this info...I hadn`t heard about it.
I hope the government has fired those `companies`/those subcontractors and is doing something to prepare efficiently in view of a major EQ in the Tokai area.

Liquefaction damage in Kawasaki / Local governments slow to inspect damage to privately owned land

Nine companies in a waterfront area of Kawasaki have suffered damage by liquefaction caused by the Great East Japan Earthquake, according to a Yomiuri Shimbun survey. The finding came after local governments in the Keihin industrial zone in Kanagawa Prefecture remained reluctant to conduct such a survey, citing their lack of authority to inspect land owned by private corporations.

Due to the municipal governments' passive stance, little was known about the extent to which corporations in the industrial zone were damaged by the March 11 earthquake. Many locations along Tokyo Bay are believed to have been affected by the earthquake-triggered liquefaction. Experts have called for a quick, full-scale investigation into the issue for future disaster management.

The Yomiuri Shimbun asked 81 companies located in Higashi-Ogijima and Ogijima districts in Kawasaki Ward, Kawasaki, about liquefaction damage following the March 11 earthquake and tsunami. Among 74 companies that responded, nine companies admitted liquefaction had been observed on their land. Of those, Tokyo Electric Power Co.'s Higashi-Ogijima thermal power plant said bumps had appeared on three roads on their premises and sand gushed out onto them.

A member of TEPCO's public relation department said: "Only the outskirts of the thermal power plant were liquefied. There was no impact on the plant itself." Fifteen to 20 ground cracks appeared on the premises of a company dealing in used car exports, as well as a bump measuring 30 to 40 centimeters. The total amount of soil and sand that gushed out from beneath the ground came to about 200 tons.

I think we can say that all of the Harbor as well as the Haneda Airport
is in a way doomed Land in the case of the next big EQ.!

In this Industrial Areas we have all types of Refineries and Chemical Engineering Facilities,
the Damage will be so catastrophically high it will make F'Shima looks good
(can i say it in this way?)

But we can say this for a big Part of the Kanto-Plain,
it is made of Gravel, Sand and a little bigger Stones
from the Mountains!

Well I know Tokyo had to feel this 5.1, although the 70 km depth will help:

That is the closest and biggest yet to strike Tokyo itself since the 9.1 hit. And that's pretty darn close. JMA has it as a 4.9, but with a high intensity level.

Ever since this started, I have just been amazed at how Tokyo has been spared from big aftershocks. Almost like it's magic. So I wonder how the JMA is going to soothe fears on this one. They don't usually get quakes that big right under the city itself, but clearly the faulting mechanism for one exists there. The earth takes its sweet time, but eventually the faults under the city are going to adjust to the earth displacement of the big one and its aftershocks.

Yes, True American. The epicenter was in Southern Ibaraki and it was felt clearly in Tokyo. The shaking went on for a bit too.

From the site I always look at it was a 5.3 quake.twiple.jp...

Had another one off the coast of Ibaraki this morning. 4.9.

You guys see where that 5.3 in Japan just happened? Damn close to the triple junction, but on the south side of the zone line:



earthquake.usgs.gov...

And I have been waiting on a JMA report on that quake, but so far nothing. Occasionally there have been times when the JMA slows down on their reporting speed, and the USGS may get out the news quicker. But usually by now the JMA would be on it. Don't know what's going on with that.



With the other smaller quake, again on that southern zone, but worse, on the other side of the line, I don't like the looks of this folks. AT ALL. Hope there is not a major rupture of that boundary, or worse a multiple failure (and multiple quakes) at the triple junction. But then again, been saying that since April. Just keeping an eye on things. Perhaps the inevitable adjustments on the southern boundaries are just now starting to manifest. Hopefully they will be smaller, gradual adjustments, instead of a second massive quake. But we could be looking at the foreshock right there.
