Quake and Tsunami in New Zealand

I'm getting lots of info off the net but not specific to boats and boaters.
Any news? 7.8 is pretty significant.

Nothing boat related on the news.. just that clean up operations have begun.
Fingers crossed nothing drastic

Re: Quake and Tsunami in New Zealand

Has anyone else taken note that earthquake activity seems to increase around the time we have 'harvest' and 'supermoons,' etc. ? Possibly the same effect on earthquakes as the tides??
================================================== =
The full moon of November 14, 2016 is not only the biggest, closest and brightest supermoon of this year. It’s the closest supermoon since January 26, 1948. Should you watch for this full moon on the night of November 14? Sure, and, if you do, it’ll be beautiful. But, for us in the Americas the moon is closer to full on the night of November 13.


The moon turns precisely full on November 14, 2016 at 13:52 UTC. This full moon instant will happen in the morning hours before sunrise November 14 in western North America and on many Pacific islands, east of the International Date Line. (See worldwide map below.)


In Asia and Australia, the moon turns precisely full during the evening hours of November 14. In New Zealand, it actually happens after midnight November 15. Around the longitudes of Europe or Africa, look both nights.
Better yet … everyone, look both nights!


The moon will look plenty full and bright all night long on both nights – November 13 and 14 – as it rises in the east around sunset, climbs highest up around midnight, and then sets in the west at or near sunrise.


The moon won’t come this close to Earth again until November 25, 2034. (Doubt very seriously I'll be around for that event!)

Big sea level differentials following the moon around the globe is bound to add to the stresses in the earths crust so not strange that EQs often happen more often during full moon/high spring tide events.

Re: Quake and Tsunami in New Zealand

Lyttelton got a series of waves starting ½ hour after main event, each about 700mm(2ft4in) peak to trough. Marinas should have been fine but there would be very strong currents in some areas, particularly around estuary entrances. ( 6 or 7 waves roughly 1/2hour apart)

Re: Quake and Tsunami in New Zealand

No problems at all for boaties.
All marinas and anchorages are ok
Enjoy your time in NZ

Re: Quake and Tsunami in New Zealand

Did anyone see the helicopter footage of the 3 cows standing on a little hill with all the rest of the ground completely gone fromaround them? It looked like at least a 15 foot drop down to where the new "ground" level is. The three cows barely had enough room to stand. Amazing scene. Cows were looking like ...'what the hell'

I was impressed with the brightness on a clear night, not sure if it was the 14th or a day earlier. As soon as my wife mentioned the supermoon I thought of earthquakes. Surenuff...

It seems the tsunami caused little or no damage to person or property anywhere in New Zealand, however the stories take some time to filter in especially in remoter areas like the Kaikoura coast where the road and it seems communication has not been fully restored yet.

I was in the port of Opua in the Bay of Islands after the serious tsunamis of the last major Japanese earthquake and was impressed with the tidal surging caused by an event so many thousands of miles away but it was no danger to vessels really provided they were moored properly. Might have been a different story for anyone game enough to be swimming.

Re: Quake and Tsunami in New Zealand

No particulate problems for boaties due to the earthquake, other than a few towns, (including Wellington, the Capital) are closed for damage assessment and cleanup (again).

A GNS survey point has been recorded as moving north 2 meters in relation to others. Enough movement to generate a Tsumami, they say. We took advice to evacuate at 3.00 am due to Tsunami risk. Nothing happened, and the turn of low tide was due around 4.00am ... a point which Civil Defence seem to ignore.

The outgoing tidal stream flows north around here, at 2 to 6 knots ... which would have been the same flow direction as the potential Tsunami.

As an entirely new thought, I wouldn't mind betting the authorities don't consider the direction and timing of tidal streams when issuing Tsunami warnings? I wave going against a 6 knot tidal stream would be a hell of a different thing from when both are going in the same direction???

Ken Ring of "predictweather" (Ken Ring, the Moonman, and lunar science - Predict Weather - the home of long range weather) become known for publicising "moon earthquake effect" after the Christchurch earthquakes.

Not sure what he's saying about the current episode (but would be prepared to bet that he'd say its all related).

Sad thought mate, those cows would not have been in that paddock on their own. They'll also be wondering where all their cow friends went, and why they left in the middle of the night without even saying goodbye.

Yes and no, there are studies of the weak correlation between the timing of events,
but there is no 1:1 link between "supermoon" and earthquakes.
[disclaimer - Geophysics has been my career]

The guys who claim to predict such things never, ever show their math.
Credibility is not part of their vocabulary.

In the other corner:
The 'experts' who claim prediction is utter hogwash are oblivious to the reality
that geophysical forces correlate, eventually, but not immediately.
We have insane bar-room brawls over some of the most obvious correlations
between earthquake energy and vulcanism,
but what is obvious after such heated discussions is that
vested interest personalities -always-always-always believe religiously
that any event has no correlation with other events.
Which directly contradicts the simplest basis of classical Physics.
Their claim on credibility is just as tenuous as seismic prophets.

The truth is we have no models to precisely predict or even recognize yet
when a seismic event will occur - the very best we can do at this point is
best described as a silly guesstimate. Someday this will no longer be true.
The amount of research into the field continues to grow,
and the folks who claim that things occur in isolation are dying off (literally).

One thing is very certain - now that a substantial event has occurred
in one area, stresses are now (as you read this)
propagating to some new and exciting location somewhere else.
There is probably less reason to be concerned about the location of
the latest event, compared to be concerned about places long dormant.

NZ should now be safe for years to come,
as to where the next big one will be is anyone's guess,
but it will hopefully be the better part of a year before anything dramatic happens.

This will be studied more competently in the future,
but there is no reason to get too excited about a supermoon event,
aside from devoting a few minutes to observe it if you get the opportunity.
Worrying about it will just distract you from living well.

Cheers
