Wow, that's a biggie!
It looks as though something is up.

SEA LEVEL READINGS CONFIRM THAT A TSUNAMI WAS GENERATED. THIS
TSUNAMI MAY HAVE BEEN DESTRUCTIVE ALONG COASTLINES OF THE REGION
NEAR THE EARTHQUAKE EPICENTER. AUTHORITIES IN THE REGION SHOULD
TAKE APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS

WARNING WILL NOT EXPAND TO OTHER AREAS OF THE PACIFIC UNLESS
ADDITIONAL DATA ARE RECEIVED TO WARRANT SUCH AN EXPANSION.

FOR AFFECTED AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO
HOURS AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE
NOT OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN
ASSUME THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL
STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS.
AS LOCAL CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE
ACTION THE ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL
AUTHORITIES.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN

#Tsunami warning Marine threat in place for Northland to East Cape

08:10, 7 July 2011

The Pacific Tsunami Warning Centre (PTWC) has issued a Tsunami Warning in response to a M7.8 earthquake near the Kermadec Islands, north of New Zealand.

A marine threat for Northland, Bay of Plenty, East Coast and Hawkes Bay has been identified.

Confirmation has been received that a tsunami was generated.

The first wave to arrive to New Zealand will be in the areas around East Cape at approximately 0852 7 July 2011. The first wave may arrive later and may not be the largest. Waves will continue for several hours.

Seems rather unfair that all the major activity seems to be anywhere BUT in the USA!

Are you guys sure that the Yanks aren't using HAARP on us???

Muzzy will ye STOP jumping off the roofs! People are going to think there are earthquakes.

Wait, there are! What are you folks doing in New Zealand? Did you upset someone - the God of the Underworld for example, or Neptune?

@westcoast: No not a precursor to a 9. I am sure of that. It would be the first time ever if it happened.

Didn't feel it this far down... and THAT fast asleep!!!

Good to see the tsunami warnings lifted.

Right.. it's about time the Alpine Fault didn't something now, don't ya think... she looks lovely this morning out the window...

With all that subduction activity on North Island it does makes you wonder whether, on a plate boundary level, it could affect the Alpine Fault - we've already seen some knock on quakes in the area between Hikurangi trench and Alpine in the Marlborough area.

edit on 6-7-2011 by MoorfNZ because: (no reason given)

Now that you mention the Alpine fault...

Should it release anytime soon, what could be the effect on the Canterbury/Christchurch region from an Alpine 8+ quake...wouldn't there be an almost guarantee of releasing further faults in the immediate region?

Considering that GeoNet predicts a 1 in 4 chance of a 6 to 7 in Canterbury, during the next 12 months, I would have thought it would be a BAD situation for us in Canterbury, if the Alpine fault releases in this time-frame.

Combined with 2-3 minutes of serious 'rolling', interspersed with other faults going off around Christchurch & Banks Penisula...GULP!

#Tsunami warning has been cancelled

0900, 7 July 2011
A tsunami was confirmed from the earthquake in the Kermadec Islands. Advice from GNS Science is that the tsunami does not represent a threat to New Zealand.

However, they expect that there will be unusually strong tidal surges and currents.

For the next 24 hours people should exercise caution and discretion before entering the water or going out in small boats in all parts of New Zealand.

Me.

Check our weather here in the U.S. we are just as bad if not worse then most of the world.

Yeah, and I'm 60km closer to Alpine than Chch .. was bad enough in 7.1 with 40/50 secs of shaking so it will be like hell on earth when Alpine goes off - I think I read up to 4 mins of shaking.

But can't live in fear - we just assume our house will be flat, or at the least VERY munted, when Alpine goes.. we've always known it was there, it's always had the potential, so nothing's changed except our appreciation (for want of a better word!) of what being in a large quake is like..

Should it release anytime soon, what could be the effect on the Canterbury/Christchurch region from an Alpine 8+ quake...wouldn't there be an almost guarantee of releasing further faults in the immediate region?

It will affect the 100's of faults all over the South Island - including the major ones and probably the ones we don't even know about yet... Canterbury/Chch will be but a small part of huge destruction up and down the south island in areas close to the fault - including transport routes - as well as potential damage to the north island depending on where, and how, the fault ruptures and the size of the quake.

Thanks for that MoorfNZ (I think)

Pretty much what's been going thru my mind, and seen's as you're CLOSER, I sure hope you and yours get thru it okay (if happens in our lifetime).

Australia's looking like a good destination, right now, but damn those pesky quakes are EVERYWHERE these days!

Thought you guys would find this interesting

LOL Yeah, crossed Melbourne off the "run to" list after I discovered it was one of the world's largest volcanic plains
