Chances of a large earthquake in Japan increasing warns Tokyo Earthquake Institute

September 1, 2011TOKYO – 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. The government’s Central Disaster Management Council has maintained that magnitude-8 quakes will not occur in the near future. But the Great East Japan Earthquake has largely changed conventional thinking about the region’s seismology. Naoshi Hirata, a researcher at the institute and a member of the government’s Earthquake Research Committee, said, “If there is drastic plate movement, there is no guarantee that the scale of the quake will be in line with the government’s prediction of up to magnitude 7.3. “In addition to looking at the intervals of recurrence of Great Kanto Earthquake level quakes, it’s necessary to review the predictions,” he said. –Yomiuri

  1. I pray for the people of Japan, but sometimes I’m surprised that island is still standing. I believe someday soon, Japan will cease to exist. Yes, it is sad, but it is something we need to be prepared for.

    Be blessed and Maranatha

      Edgar Cayce

      Still dragging up this old platitude?
      The world has changed since Cayce was alive.


      • Pagan says:

        It most certainly has changed & continues to do so, & in many ways just as he predicted.

        to NoSlide:

        Why do you refer to Cayce’s reading as a platitude?

        plat·i·tude   [plat-i-tood, -tyood] Show IPA
        1.a flat, dull, or trite remark, especially one uttered as if it were fresh or profound.
        2.the quality or state of being flat, dull, or trite: the platitude of most political oratory.

        Edgar Cayce accessed the Akashic Records when in a trance state and none of his verbal communications when in this condition can remotely be considered “platitudes”. Since he did not give any timeline with this comment, it may well hold up someday.

        Did you know that Cayce was over 90% accurate with regard to his remedies for health problems? Why then would his predictions not be equally accurate? He did stress the point, however, that mankind can change outcomes of any of his visions.

        With the current nuclear disaster in Japan, “going under the sea” may be a likely karmic outcome, if you believe in such things.

    An earlier posting reported that the goverment was considering relocating the capital.

    Speaking about EQ’s, the washington post is reporting that there has been 19 aftershocks from the august EQ in Virginia and in one county of 35,000 there was 17 million dollars in damage.

    Goodbye Japan. 😦


  6. Isn’t it just possible that considering that these poor guys are just “covering their hind-ends” considering the raking-over that they received after failing to predict the big one? I would.

      Hi Alvin we have just had a 4.9 in Christchurch NZ another shallow one this follows on a 4.0 and 4.7 we had on Wednesday with the continuous little ones in between. They keep telling us its quitening down but when we got the Wednesday quakes the scientists were “suprised” Do you think these could have anything to do with what is happening in Japan? Getting fed up with being woken in the early hours.


      • I think the whole Ring of Fire is becoming more volatile Sophia and the South Pacific, in particular, is a region that is being hammered right now by an inordinate amount of seismic activity and is one we should be very gravely concerned about. I hate to say this but it appears the tension is not dissipating…it looks to be rising.

    Shinmoedake Kirishima, according to the Meteorological Observatory Fukuoka District, a small eruption occurred at 2:00 43 minutes. The plume rising to a height of 500 meters

    I am deeply saddened by what has affected Japan and the Japanese people. I have a deep love for Japan and have always been drawn to it. I will pray for them but it is hard to see people saying it will disappear into the sea. I was beyond devastated to witness the tsunami live and still am shaken by everything that is happening in our world. My faith is strong but my heart is heavy.
