M5 class of earthquake hit Japan 4 times in 2 hours

The first 3 happened in Yamanashi ken around Mt.Fuji. People are tweeting about the unusual earthquake sound.


揺れ方が違ってた。地鳴りが強くなったような揺れ。ずっと微妙に地鳴りがしてる気がする。いつまた来てもおかしくないような。震源地が近いから?山だから? 富士山大丈夫か?Source


The way of shaking was different from usual. It felt like a strong brontide caused the earthquake. A slight earthquake sound can be still heard. It is not unusual even if another one comes anytime again. Is it because I’m near the epicenter ? is it because mountain ? Is Mt.Fuji ok ?





The announcer who did the live report near Mt.Fuji on “Tele Asa” was saying, it felt like a brontide went under my feet.



Another person posted the picture of Mt. Fuji.

It looks like steam is splashing from 2 locations.

Meteorological bureau held an emergency press conference to deny the connection between the series of earthquake to eruption of Mt.Fuji. This statement is making people more anxious because Japanese government has been deceiving its own people about Fukushima accident.




Meteorological bureau held a press conference at 9:40 AM to tell the earthquake to have the epicenter in Yamanashi ken has nothing to do with volcanic action of Mt.Fuji or potential Tokai earthquake. It’s based on the data about crustal change.


  1. Please keep it up Mochizuki-san! The international media’s being really, frightningly quiet about what’s happening in Japan. I wouldn’t be surprised if you and SPKF were the only real news coming out of the country.

  2. Just saw this:

    But Navrotsky and others have since discovered a new way in which seawater can corrode nuclear fuel, forming uranium compounds that could potentially travel long distances, either in solution or as very small particles. The research team published its work Jan. 23 in the journal Proceedings of the National Academy of Sciences.

    “This is a phenomenon that has not been considered before,” said Alexandra Navrotsky, distinguished professor of ceramic, earth and environmental materials chemistry. “We don’t know how much this will increase the rate of corrosion, but it is something that will have to be considered in future.”

  3. I sincerely hope this does not result in an eruption at Mount Fuji. This would be far too much for Japan.

    A notice to Mochizuku-san. If I may offer one bit of advice, please edit your front page so that the posts show the comment link. You updated your site design before and this comment link has disappeared so now there are few comments for your posts.

    It should be easy to add this by simply copying that php code from the single post page source and including it in the front page. Please consider it as it will increase the number of comments again.
    Enjoy the weekend. お疲れ様です。

  4. More quakes = More radiation released…

    Hopefully the IAEA will be there to measure it!

    Has anyone seen the radiation charts for the last week; they should be showing massive additional radiation since there have been many quakes!

    The missing corium(s) are being shaken as they are drawn downward by gravity!

  5. Heavy rains and or snow pack all increase the upward pressure of the ground water “table”. Since the corium(s) are being drawn ever downward by gravity and often by the forces of large additional Earth Quakes (EQ’s), IMO we are seeing the interaction between the Corium(s) and the water below the Fukushima Complex!

    The EQ’s also provide what I call a nuclear “kick start” to the fissioning that is responsible for the increased radioactivity that has been detected soon after these EQ’s.

    Another consideration is the Temperature and MASS of these Corium(s) which are huge as compared to the subsurface materials and temperatures below the Complex… Think H☢T nuclear knife cutting into soil butter!


    My money is on “The Fuky Effect”, causing much if not all of the periodic radiation releases and it is doing it all by itself (ie. not in a controlled manner)!
    Here is my thinking:
    1. I believe that the Corium is now completely below the RPV and so any reading taken above it, are going to be MUCH lower than expected (which matches the data observatio­ns above).

    2. The Corium molten mass is probably now below the “base mat” or floor of the containmen­t structure and is working its way into the landfill below, which would allow most if not all radioactiv­e gases to disperse to the atmosphere­, instead of being contained in the holed RPV…

    3. The Ocean water will show increase RAD readings due to the leakage being washout out from around and below the reactor due to the HUGE rains…

    4. A Corium/Wat­er steam event is still very much a possibilit­y + if it is happening very slowly then that would explain all the fluctuatin­g increases in RAD reading north of Tokyo!

    Good Luck Japan!

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
