Strong 7.8 magnitude earthquake strikes off Japan’s coast – shakes buildings in Tokyo

Japan 7
May 2015JAPAN A powerful undersea earthquake south of Japan has shaken buildings in Tokyo. The US Geological Survey said the 7.8magnitude earthquake was centered 874km (543 miles) from the Japanese capital, at a depth of almost 700km. It struck at 18:30 local time (11:30 GMT). Buildings in the capital swayed for almost a minute as the quake built in intensity, AFP news agency says. There are no reports of serious damage or casualties. No tsunami warning has been issued. Tokyo Electric Power Co said there were no abnormalities at the crippled Fukushima nuclear power plant following the quake. The runways at Tokyo’s Narita airport were operating normally but the high-speed bullet train service between Tokyo and Osaka was halted due to a power outage, the broadcaster said.BBC
At a depth of 677 km, this is the deepest large magnitude earthquake ever recorded. It was originally measured as an 8.5 magnitude event – something that was previously thought impossible. The planet is beginning to see more of these deep quakes- We had one just 2 years ago on May 24, 2013 (almost exactly 2 years to the day) in the Sea of Okhotsk, a 8.3 magnitude quake at 609 km and it astounded scientists – as large magnitude earthquake don’t usually occur at such depths. Tremors from today’s earthquake were felt all the way to Nepal and India. Think about it – New Delhi is 5,834 km (3,625 miles) from Tokyo. –TEP

  1. Both the WCTWC and the PTWC have listed the quake as a 8.5 which is what I would go along with based on symptoms and previous observations. I had a timeline I posted to my group for the 24-31 of May for 7.0 or greater, then after the 7.8 in AK yesterday, I sent a message to the WCTWC and told them it was not over based on my observations and timelines another 7.0 or greater was possible… and then the 8.5 at 4:23 AM PDT this morning. I had Popcorn for dinner the last 2 nights and craving sweets/carbs and finally major ant invasion.

    This is extremely deep. Alvin, what indications does this particular deep thrust or was it a slip-strike earthquake have for that huge canyon rift running next to Japan? I guess we can watch and see, but does the depth mean that the actual plate moved? Thanks for all your news as always!

    • Hi Patty. It’s very worrisome. Not a megathrust – but definitely subduction, and geologists around the world will be studying this event for some time. It’s a complex plate movement that may involve something called a microplate under the sea-floor. At a depth of 677 km, this is the deepest large magnitude earthquake ever recorded. It was originally measured as an 8.5 magnitude event – something that was previously thought impossible. The planet is beginning to see more of these deep quakes- We had one just 2 years ago on May 24, 2013 in the Sea of Okhotsk, a 8.3 magnitude quake at 609 km and it astounded scientists – as large magnitude earthquake don’t usually occur at such depths.

      Change is intensifying. You’re welcome and take care.

        That’s insane.

      • Isn’t it? This is from the Live Science article on the Sea of Okhotsk 8.3 (609 km) quake on May 24, 2013

        “This setting makes for deep earthquakes in the subducted Pacific plate crust. The extraordinary depth of today’s earthquake also means the shaking traveled far across Russia, reaching Moscow and rattling the Kremlin 4,000 miles (6,400 km) away. The waves also crossed the United States, as seen in this video from the Incorporated Research Institutions for Seismology.”

        http://www.livescience.com/34671-russian-earthquake-deepest-ever.html

        So we can probably surmise – all these deep quakes are the beginning of changing processes within the planet and is building towards something great that is capable of shaking the entire planet.

        “No earthquake like it has ever occurred since mankind has been on earth, so … was not since men were upon the earth, so mighty an earthquake, and so great.” -Rev 16:18

        If I had to guess – I would say this could be from a deep earthquake.

    Depth of 700km??!! That is a statement more than the magnitude

    I agree with Whyte on this: 700 km IS a statement, a MOUTHFUL, in fact, considering that, whether its depth is approximated to be 40 km:

    . . . or 50 km:

    . . . or 70 km:

    http://thebritishgeographer.weebly.com/plate-tectonic-theory.html

    . . . 700 km is FAR below the actual crust of the earth, and, according to the British Geographer site (above, picture 2), into the lower mantle. So, assuming that my roodimentary understanding of the earth’s core is even remotely accurate, how is it physically possible for such tectonic activity to transmit through the “partially melted rocks” of the asthenosphere (enough to sway buildings in Tokyo)? Or does it mean that, at 700 km, the activity was more like, oh, 17.2, and what was observed a “mere” 7.8 in comparison?

    Are these being caused by CERN ?

    Perhaps, instead of looking inward, we should outward. Perhaps the cause or part of the cause is
    coming from an external source? For example, there has been a number of Geomagnetic events from the sun.

    I guess what I am attempting to say is that there could be external pressure? The earth seem to be according to Scientists, to be in an active seismic time/era?

    Rupture characteristics of the deep bolivian earthquake of 9 june 1994 and the mechanism of deep-focus earthquakes.
    Silver PG, Beck SL, Wallace TC, Meade C, Myers SC, James DE, Kuehnel R.
    Abstract
    The M(w) = 8.3 deep (636 kilometers) Bolivian earthquake of 9 June 1994 was the largest deep-focus earthquake ever recorded. Seismic data from permanent stations plus portable instruments in South America show that rupture occurred on a horizontal plane and extended at least 30 by 50 kilometers. Rupture proceeded at 1 to 3 kilometers per second along the down-dip azimuth of the slab and penetrated through more than a third of the slab thickness. This extent is more than three times that expected for a metastable wedge of olivine at the core of the slab, and thus appears to be incompatible with an origin by transformational faulting. These large events may instead represent slip on preserved zones of weakness established in oceanic lithosphere at the Earth’s surface.

    Magnitude 8.2

    Unconfirmed reports of five people killed in Peru; three in Arequipa Province by a landslide collapsing their house and two in Cuzco Province; one by falling debris and another by a heart attack. Numerous injuries and landslides occurred in southern Peru. Damage (VI) at La Paz. In Cochabamba, La Paz and Oruro, a large number of windows broke in tall buildings, and some structural damage occurred. Some minor structural damage also occurred at Brasilia, Campo Grande, Porto Velho and Manaus, Brazil; Arica, Chile and Tacna, Peru. Felt in many parts of South America, including most of Argentina, Bolivia and Brazil. Felt lightly in Uruguay. Felt (IV) at Arequipa, Moquegua, Puno and Tacna; (III) at Moyobamba, Rioja and Tarapoto, Peru. Felt (IV) at Arica, (III) at Iquique, (II) at Copiapo and (I) at Santiago, Chile. Felt (IV) at Guayaquil and (III) at Quito, Ecuador. Felt on Puerto Rico and in the Dominican Republic. Felt at many locations in North America, including Los Angeles, California; Renton, Washington; Omaha, Nebraska; Sioux City, Iowa; Minneapolis, Minnesota; La Crosse, Wisconsin; Chicago, Illinois; Parkersburg, West Virginia; Norwich, Connecticut; Boston, Massachusetts and Toronto, Canada. This is believed to be the first earthquake from this part of South America to be felt in North America and is also believed to be the largest ever recorded in this general area.

    I remember a Christian leader having a vision of a huge quake right before this happened in 1994. At the time I wondered if there was going to be a complete rupture of an entire plate.

    How does this compare Alvin to the current one as far as characteristics and significance?

    Thanks
