7.6 magnitude earthquake strikes tectonic plate boundary near Kermadec Islands

July 6, 2011KERMADEC — A powerful magnitude- 7.8 earthquake rattled New Zealand’s remote Kermadec Islands in the Pacific Ocean, the U.S. Geological Survey reported. The quake was later down-graded to a 7.6 by the USGS. The Kermadec Islands are a remote outpost that is generally uninhabited aside from a weather station and a hostel for visiting New Zealand scientists. The 7:03 a.m. Thursday (1903 GMT Wednesday) quake was 29.8 miles (48 kilometers) deep, the USGS said. No tsunami alert was issued. The Kermadecs are about 570 miles (920 kilometers) south of Tonga, the nearest major island. –The Houston Chronicle
Tsunami Warning WELLINGTON— New Zealand’s Ministry of Civil Defense and Emergency Management issued a marine threat for the country’s North Island after a magnitude 7.8 earthquake struck in the Kermadec Islands region in the southern Pacific Ocean early Thursday morning New Zealand time. “Confirmation been received that a tsunami was generated,” the Ministry of Civil Defense said. It said a marine threat for Northland, Bay of Plenty, East Coast and Hawkes Bay had been identified. All are located on New Zealand’s North Island. The ministry said the first wave would arrive in New Zealand round 8:52 a.m. local time. “The first wave may arrive later and may not be the largest. Waves will continue for several hours,” it added. It called on people to stay off beaches, stay out of the water and not go sightseeing. Meanwhile, the Pacific Tsunami Warning Center canceled a tsunami warning for the Kermadec Islands, Tonga and New Zealand. It said “sea-level readings indicate a tsunami was generated. It may have been destructive along coasts near the earthquake epicenter.” –Wall Street Journal


Update: Global seismograms go into the black. The aftershock pattern intensity for Kermadec is unusually strong. Please stay tuned to this region.

    There is one site on the internet that predicted this earthquake quite accurately. Not a prophetic site, but using the idea of gaps in the coronal hole and sun flares, as well as recent patterns etc. I haven’t read that part of your book yet but do you have any comments on the science behind that? I think it’s interesting – and not the first time he’s been right.


    • I don’t know of any science behind it but if he has found a way to make credible predictions based on solar data sets, I say maybe he has found a system of relevancy- not that it indicates it’s scientific. Earth is not the only planet believed to possess tectonic plates and it is not the only planet that has quakes- so, you would have to isolate one planet (Earth) in the experiment to prove any possible connection and that it’s the only planet being perturbed by solar phenomena.

    Supposedly a 20:52z NZ arrival, thats in a few mins, I am watching the ocean here: http://new.eol.co.nz/community_webcams mount wave cam

    As far as I understand a Warning has indeed been issued. Here is the link….


  4. AWatchman4Him says:

    Actually, there was a Tsunami warning issued, but they called it off.


  5. Greg says:

    Alvin – The Blase is reporting that a tsnuami warning was issued and, in fact, a tsnuami WAS generated. From The Blase: A 7.8 magnitude earthquake near the Kermadec Islands, roughly 500 miles north of New Zealand, occurred Wednesday (early Thursday morning New Zealand time). Tsunami warnings are in effect.

    UPDATE: Reuters reports that a tsunami was in fact generated. According to breaking news reports the tsunami could reach East Cape and Auckland New Zealand in a matter of hours.


  6. Daniel says:

    One thinks of Tanna and other islands in that patch of the ocean near Eastern Queensland, this is on a line with the New Hebrides now called Vanuatu. Magnitude 8 quakes are fairly common in that zone but when near Indonesia claim hundreds of lives in the tidal waves that sweep coastal villages away.


  7. Reece says:

    I fear this may only be a prelude to something of a far greater scale which could be yet to come. Earth changes are accelerating and it seems as if something vast is on the horizon.


    • PansPermia says:

      Reece there’s no doubt about that. One thing usually leads to another. Be ready/prepared for anything and I mean anything. Keep a supply of any and everything you might need in case of a disaster at the ready.

    Here’s what the Australian Herald Sun says:
    A TSUNAMI has begun travelling across the Pacific towards New Zealand and Tonga after a powerful 7.7-magnitude undersea earthquake, the Pacific Tsunami Warning Center says.

    Tsunami waves were measured off Raoul Island, one of New Zealand’s Kermadec Islands, up to a height of 84cm above normal sea level, the centre said.

    “Sea level readings confirm that a tsunami was generated,” the centre said.

    “This tsunami may have been destructive along coastlines of the region near the earthquake epicentre.”

    The tsunami could reach Tonga by 6.17am AEST and the eastern cape of New Zealand by 6.52am AEST, the centre added, advising that if there were no damaging waves for two hours after the initial warning, local authorities could assume the threat had passed.

    The quake struck at 05.03am AEST today at a depth of just 1km, the United States Geological Survey (USGS) said.

    Its epicentre was 160km east of Raoul Island and 914km from the Tongan capital, Nuku’alofa.

    USGS revised the quake’s magnitude slightly downward from an earlier reading of 7.8.

    Hi Alvin, hope all is well with you 🙂 i would be interested to hear your thoughts on this regions activity at present & also for the areas surrounding, such as nz, australias east coastline? kind regards, Nat.


  11. sophia carlson says:

    That aftershock pattern looks very scary!


  12. Gen says:

    Sophia, I agree about the pattern. I looked on USGS for a listing of quakes on 9, 10 and 11 March but cant find one. I printed out quakes pages to show my sister because her computer was out of action.

    So to give an indication of what might be coming, here is an overview of pre tsunami Japan.

    9 March “out of the blue”‘ a M7.2 off coast of Honshu Japan
    then 19 ‘aftershocks’ from 4.7 to 5.7 over a 15 hour period
    then a 6.1, 6.0, 6.1 over a 3 hour period
    then a 5.4 and 4.8

    10 March 10 ‘shocks’ from 4.6 to 5.7

    11 March swarm of 5 quakes in Hawaii region
    then the big one and tsunami the 9.0 off Honshu Japan

    For the next four hours there were endless ‘shocks’ off Japan but they were virtually “bouncing backwards and forwards” between Japan and Hawaii for the next four hours. Then quakes started showing up in Alaska.

    We will have to wait and see what happens in Kermadec Islands. Trouble is that is a monster of a place by the sounds of it, under the ocean I mean.


  13. Gen says:

    A strange thing happened about an hour before dark yesterday 6 July (here in Australia). We have been having high winds and I was sitting on the lounge looking out through the back window. Above the tree line the sky was grey and white and the clouds were moving quite fast from I guess SW to NE. I have never seen clouds look like it before. The more I looked, it was as though I was looking at the ocean with waves and foam rolling in. I thought about an article I read about tsunami clouds over Japan and wondered if that was what they meant.

    If only I had been able to get a photo.


  14. Gen says:

    7 July M2.7 Kalgoorlie Western Australia listed as signficant
    5 July Melbourne and M2.7 NW Gulgong NSW depth 0 (not known?)
    17 June M2.5 NE Mudgee NSW depth 10km listed as significant

    Mudgee is 30 kms from Gulgong

    This video explains what lies beneath the Kermadec Islands & includes deep sea footage & a first hand account of the earthquake:



  16. Gen says:

    Maiden PEI thank you for the video link. Now that is what I call responsible reporting by the media.

    Good to see it.
