Graham Furniss, who is one of our original members and the husband of Sally told me that they are ok. Since it was 1 am local time in Christchurch when I called, I simply conveyed our good wishes for them and got off the phone. The first call I made did not go through. I suspect some trouble on the lines.

Our best wishes to everyone affected by this set of earthquakes.

Having had nearly 14800 quakes since September 2010, it came as quite a terrible shock for most of us. We now tall over 15,027 quakes since Sept. 2010 and these are some of the worst as the damage is much more widespread. The North and East Coast of the South Island are shaking still and there are damages to roads around the capitol city Wellington and Marlborough Sounds have land slippage of 3 to 4 meters on the road from Kaikoura northwards.

Tsunami hits New Zealand after deadly 7.5 magnitude earthquake

A tsunami has hit New Zealand after a powerful earthquake struck the country's South Island, with the country's prime minister so far confirming two deaths.

Thousands on the country's east coast have fled after a warning to move to higher ground.

The Civil Defence Ministry said people close to the epicentre could see waves three to five metres high after the quake, measured at 7.5 in magnitude.

The ministry described the tsunami as "an event of life-threatening or national significance".

Waves of up to between 1.5 and two metres have already hit the Kaikoura area, according to New Zealand's Geonet group.


The Civil Defence Ministry tweeted: "A tsunami has been generated, the first wave has arrived in the North Eastern Coast of the South Island."

It added: "The first wave may not be the largest. Waves may continue for several hours...

[Sally Furniss]

it hit a few minutes after midnight, it was a very long long quake, long and rolling..... we felt many after shocks overnight.

[Gert van der Hoek]

Must be scary Sally, glad you and your family are OK.

[sharon sanders]

it hit a few minutes after midnight, it was a very long long quake, long and rolling..... we felt many after shocks overnight.

I had a conversation again later today with Sally and she gave me this link (with some videos) to look at:

Evidently the main road that connects Christchurch to the port at Picton (across the strait from Wellington) is broken in several places. At least one tunnel is collapsed. Picton is the main passenger and freight port for the Southern Island.

[Roehl_JC]

We have had about 200 quakes since midnight and much of New Brighton evacuated after tsunami sirens. Bless you Sally and Graham and Sharon and Shiloh.

NationalKaikoura earthquake

Tuesday 15 Nov - 12:32 am

The Ministry of Civil Defence and Emergency Management is reminding people affected by the Kaikoura earthquake to keep themselves up to date and stay prepared for further aftershocks. People are asked to follow the advice of local Civil Defence groups and stay informed through media and social media reports. The quakes triggered a tsunami warning which has now been cancelled. There is no longer any tsunami threat to any area of NZ. However coastal areas may have unusually strong coastal currents or sea level fluctuations for some time and we continue to advise people to take extra care around the water. Civil Defence Emergency Management Director, Sarah Stuart-Black said, ?If it?s safe for you to stay in your home or return home, then do so. Look after your neighbours and loved ones and remember to drop cover and hold during aftershocks.? Mrs Stuart-Black said, ?Civil Defence and Emergency Management groups across the country have spent today working with and checking on their communities. New Zealanders are shaken but are coming together and supporting each other. If people have tried all available contact methods to reach loved ones and been unable to do so they should contact their local Police station.? Expect aftershocks and remember to drop, cover and hold. Look after yourself and get first aid if necessary. Help others if you can. Building assessments should be done before buildings are opened for normal use, particularly in areas which experienced strong shaking such as the CBD areas of Wellington, Christchurch and Blenheim. Watch out for fallen power lines or broken gas lines. Stay out of damaged areas. Listen to the radio for updated emergency information and instructions. Do not overload phone lines with non-emergency calls. Text friends and family to see if they are OK.

M7.5 Kaikoura Earthquake: Latest updates

We are getting more information from our science reconnaissance teams and are sifting through the mountains of data to develop a better picture of this earthquake. We have new information about the fault ruptures, and have initial estimates on which faults were involved.


Multiple ruptures

Rapid field reconnaissance indicates that multiple faults have ruptured:

• Kekerengu Fault at the coast - appears to have had up to 10m of slip
• Newly identified fault at Waipapa Bay
• Hope Fault - seaward segment - minor movement
• Hundalee Fault

In the simplest case an earthquake is a rupture on a single fault plane.
What we are finding in New Zealand is that quite a few of our larger earthquakes involve jumping from rupture on one plane to another in a complex sequence. We first saw that with the Darfield Sept 2010 EQ where multiple segments ruptured together as a single earthquake. We appear to have seen this again overnight.

In terms of what might happen next: The scenarios provide an overview of how we see this earthquake sequence evolving over the next few days to one month. What is on the web page is our best information that we have to hand at the moment. As our science information flows in over the next few days we expect that information may evolve.

ShakeMap for the M7.5 Kaikoura Earthquake.

A word about the Moon

Some people have raised concerns about a link with the supermoon. In large groups earthquakes exhibit slight associations with lunar cycles, but this is not reliable for forecasting. We have two tides a day throughout New Zealand and at any one place there is no clear association in location. The occurrence of the full moon around the globe does not allow us to say how big, when and where any earthquake might be.

Long term earthquake rates

There were more large earthquakes in a period of several decades prior to about 1950, and it has been relatively quiet since then. Since the M7.8 in July 2009 in Fiordland, that quiet period appears to be over. The reason we had a tsunami generated by an earthquake with an epicentre onshore is that there was deformation further down the fault plane offshore.

Wellington area
Wellington area faults and the subduction interface beneath Wellington are captured in the probability table and the scenarios given there. We do not have any evidence of an impending large earthquake of a similar size in Wellington at this stage but we cannot rule this out. We cannot make a calculation to predict this, but the chance of a further shock in the Wellington area has increased somewhat since the Kaikoura earthquake.

Why were our magnitudes different from the USGS: About magnitude variability
We have currently established that the New Zealand local magnitude for this earthquake is 7.5, but this may be reviewed over time when more detailed research is undertaken. This may bring it closer to the internationally-derived value (e.g. Mw7.8 by the US Geological Survey).

Felt it? Tell us about it.
Our Felt Detailed report for this earthquake is now available. Please help us by filling out this report to help our long term research programme.

Looking forward

We will be continuing to gather information about this earthquake for some time. We will continue to keep updating information as we learn more about this earthquake.

Be prepared ? both physically and mentally

Beyond physical preparedness is the emotional and psychological support for these earthquakes. The All Right? Hotline (0800-777-846) is a great resource where you can talk about any anxieties or concerns that you have regarding the earthquakes.
Want to know more about you can get ready? Check out the Ministry of Civil Defence and Emergency Management's website for more information.
