Our regular poster, Ian SC, is from that area I believe - hope all is well. Trust he will let us know in due course.

+1.

V8.

Its a lot bigger than the 2011 one, but it looks like its deeper and further away from big settlements. Hopefully that means casualties and damage will be a lot less.

Best wishes to everyone in the area.

What's the time difference between UK and NZ ? Ian SC was on at 08.32 forum time. Nathan

Wellington is +13 hours

I am sure he will be fine.

He's a Kiwi. ........... Those guy's chew rocks for breakfast and then still hungry again by 11am

But being serious. It was a big quake so I would imagine some infrastructure issues. One may be the internet connections of many folk.

Hi All, Ian is south of the most affected area...he is actually pretty close to the epicentre of the first Canterbury quake near Darfield...so hopefully things should be OK there. There has been loss of power in some areas.

There are two known fatalities so far. As Neil says, it is a reasonably sparsely inhabited area, although Wellington is close enough to have copped some damage. The area is quite mountainous so there are landslides and damage to roads and rail. Also there is some bad weather heading for that area, which is not really what you need at a time like this.

We felt it quite strongly here in Cambridge, which if you check your maps you will see is quite a way up the North Island. We heard something tapping the wall, a belt or a strap or something, then realised that the bed felt a bit like it was on a boat. We took shelter in a doorway, as the shaking went on for quite some time...I knew from that that it was a big one somewhere. It was felt pretty much the length of the country.

The boffins are saying that it was actually two quakes practically simultaneous, one near Kaikoura which was a thrust fault and one further north which was slip-strike. There are also aftershocks now, and those who have followed the Canterbury quakes will know that this can go on for a very long time. The quake that killed so many in Christchurch was actually an aftershock of the earlier Darfield quake. There is also a 20% or so chance that this is all a precursor to something bigger. This one was magnitude 7.5, the Darfield one was 7.1. That actually means that this was about 4 times the energy. But of course the damage is another thing, that depends on local conditions like soil properties and of course density of population.

I am in Hamilton and it was felt here. A friend lost about 1/2m of water out of his pool just filled in the weekend, about 18 inches in real measurements. The lights were swaying at work this afternoon from an after shock. On the news they just mentioned that the fault area is about 100 km long, so one of the biggest known for here in recent times.

Best Wishes to all

This would be one hell of a ditch to wake up to, hope and prayers for anyone involved...

My daughter lives just south of Dunedin and slept through it.She didn't know about it until her husband, a volunteer fireman was called in to duty.

I was sitting here at my computor when things started to move switched on the radio so I could hear what was going on, then I went to go to the GeoNet site to see where the earthquake was, and found I'd gone off line (dial up), got back on line. As I'm the street coordinator for the Neighbourhood Support Network (started after the quakes 6 years ago), I thought I should get out and about to see if anyone was having a problem.

Funny thing happened yesterday, a new family moved in across the street, so off I go to introduce myself , and the support network!

The quake here felt about the same as the big one in central Christchurch, not too bad. Darfield is situated out on a vast alluvial plain, and this dampens the earth movement (just having an after shock).

Glad you and Kiwi members are OK.

Now is probably not a good time to mention liquefaction then

Neil

Neil;

My year in Wellington, quite a while ago now, I learned quite a few new words - that Tsunami one - I asked what all the signs meant and was told (of course), and, over the hill from Lower Hutt there was a small town where it was all subject to liquefaction, so no new building was allowed there.

And, why Lambton Quay in Wellington was not on the water, and why the cricket pitch was called "the Basin" - one day a century or more ago the land rose something like 13 feet...

My first day of work, there was an earth quake as I was trying to decipher what train to take home that night; I did wonder why the stone building was shaking, and why everyone suddenly knew that they'd be delayed... (it was a mild quake)

Interesting place to live, and very interesting people. I, too, wish that all are safe.

John.

Here is some video footage of the railway line around Kaikoura there was only one train operating in the area, they stopped it and tied it down. http://www.newshub.co.nz/nznews/kaikoura-rail-line-decimated-2016111413

With that amount of earth movement, miraculous no greater loss of life.

(also seriously impressed with the apparent tensile strength of that continuously-welded rail!)

We didn't have liquifaction here in Darfield, and I didn't collect a sample from the city, it seems to make quite a good grinding paste.

Quite a lot of Wellington is built on reclaimed land, as are some other cities here, these areas tend to liquify in earthquake conditions. Christchurch is built on swamp, and sandy areas.

The poor people stranded in Kaikura are having to put up with eating Crayfish and salad.    Ian S C

Here is a photo from the previous quake showing what can happen to welded rails.

You just can't trust that flexi-track.
