MikeB4:

I really hope we do not get any further significant after shocks. I think we will see a real mess in the capital if this continues.

The Wellington Quake Live site seems to be graphing quakes from the re-activated Seddon area where most of the aftershock activity affecting Wellington is coming from.

So - it's looking okay - it is dying down even if it doesn't feel like it.

More pronounced decay in the N Canty region covered by the Canterbury Quake Live site.

Usual disclaimer that it's very complex - Geonet has high probability (91%) of 0-6 M5 to M6 shakes, lower (22%) probability of 0-2 >M7 shakes over the next 30 days.

But that's over the larger region, which does include Wgtn itself, even if probably they'd be closer to existing activity.

Chch decay sequence showed us what can happen. Fewer quakes doesn't mean that there won't be some nasty ones.

I agree. It's not that they're a significant hazard if on single floored dwellings and well tied-back, and they're also about the cheapest cladding material and can be easily re-clad if they do fail in a quake. The problems IMO are that if you're in a city like Chch and your bricks get buggered by a quake, the same probably happened to tens of thousands of other houses, so you'll be waiting a long time (years) to get them fixed. The weight also means more interior plaster damage etc. Round about the level of shaking (0.25g pga) Wgtn had in the past couple of days is the point where some failure of mortar (minor cracking) could be happening on modern brick-veneer homes built to current code.

Vodafone update:

Worst-affected quake communities to benefit from Vodafone funding boost

Vodafone has today contributed a significant donation to the Red Cross November 2016 Earthquake Appeal to help communities in Kaikoura and Blenheim left struggling after Monday’s devastating 7.5 earthquake.

With network recovery well underway and mobile and broadband services almost fully restored to communities across the lower North Island and upper South Island, Vodafone has turned the spotlight on the relief effort for some of the worst affected communities.

As a demonstration of our support of the valuable work carried out by the Red Cross to support residents and visitors of the Marlborough and upper Canterbury region, Vodafone has donated $150,000 to the Red Cross November 2016 Earthquake Appeal, through its charitable trust, The Vodafone New Zealand Foundation.

Vodafone New Zealand Foundation Chair, Antony Welton said, “When Kiwis are affected by disaster we know how important it is to provide the right support.

“We wanted to make a difference with relief efforts right now, as well as contribute to both the long-term rebuild, and emotional well-being of residents and visitors who have been affected by the quakes and continued aftershocks,” Antony said.

Red Cross Secretary General Tony Paine said he was extremely thankful for the show of generosity.

“As we know from our Christchurch experience, there will be a lot of people who have lost a lot and facing very tough times, just to get their lives and houses back to normal” Tony said.

“We are just so thankful to organisations like Vodafone, and generous Kiwis who always seem to come to the fore when communities really need it” Tony added.

As well as a significant contribution to the November 2016 Earthquake Appeal, Vodafone will support the Red Cross fundraising campaign by making it easy for all Kiwis to donate.

Vodafone has committed to cover the costs associated with the Red Cross November 2016 Earthquake Appeal text fundraising campaign, so one hundred percent of all money donated will go directly to the emergency response.

Antony Welton said, “It’s becoming increasingly clear from the reports by the Red Cross team on the ground just how traumatised people are.

“There is a massive need for support of nearly every kind, and the best thing we can do is provide money to the Red Cross to make sure they can allocate the right sort of support where it is most needed,” Antony said.

Kiwis can make an instant $3 donation by simply texting RED CROSS to 3181. People can also visit www.redcross.org.nz/donate to give to the November 2016 Earthquake Appeal.

For more information on how to donate and updates on fundraising efforts, please visit: www.vodafone.co.nz/redalert

Vodafone is continuing to work closely with other telecommunications providers to ensure connectivity to support the community, and incoming emergency service workers.

Spark update:

Spark Update | Spark network

2.45pm

Spark restored mobile service to Kaikoura at 10am this morning. We’re working with Vodafone and Chorus to get broadband and landline back into town using Vodafone’s offshore Aqualink. If no problems are encountered, it is expected that landline and broadband may be restored later today or early tomorrow to Kaikoura. You can read more about progress in our joint release with Chorus and Vodafone below.

We’re still working on restoring mobile, broadband and landline coverage to people in Waiau. The fibre cable that allows all these services in Waiau has been buried under an 800m landslide, so we are working to get mobile signal into the town using a microwave link, that will connect the Waiau site to our network at the nearby cell site at Mouse Point.

Some people in the area around Clarence and south of Seddon won’t have mobile coverage, as two cell sites are down in the area. One of the cell sites, Weldcone, has been damaged; techs are currently working on diagnosing the work needed to get the site up and running. The other cell tower, Clarence, relies on a fibre connection running down the east coast that has been damaged and will take time to fix. Spark is looking at using a microwave link to a nearby cell site to bring mobile coverage to the Clarence cellsite.

Spark has teams of techs working all round the affected areas to get services up and running. Weather conditions (flooding, rain, fog and so on) make the work more challenging, particularly as many areas can only be accessed by helicopters, which require reasonable weather to fly.

Yeah brick repairs to mortar from these quakes is just a big cost which everyone will be paying for in future insurance costs. Also the mass they add to the house when he house has lateral movement, causes more force on a house eg Force = Mass x Acceleration.. IMO keep a house light weight to be safe with weatherboarding or other sheet materials. Bricks maybe a cheap cladding solution, but it could be false economy in earthquake areas. Either that, or just charge higher premiums to those with houses clad or built in brick.

That must be why there were never any earth quakes before humans arrived in NZ.

Well id hate to think what they did wrong in Napier in 1931..

I was looking further into it on wikipedia and noted this:

"The local landscape changed dramatically, with the coastal areas around Napier being lifted by around two metres.[5] The most noticeable land change was the uplifting of some 40 km² of sea-bed to become dry land. This included Ahuriri Lagoon, which was lifted more than 2.7 metres[5] and resulted in draining 2230 hectares of the lagoon. Today, this area is the location of Hawkes Bay Airport, housing and industrial developments and farmland."

Similar rise in sea bed levels.. Hmm the whole country is slowly raising itself :)

Wellington is another example. The Basin Reserve area was a port. Along Lambton Quay you can see the marks showing the previous sea level. All the terraces that you see on the hills around Wgtn are old sea levels which have subsequently been uplifted.

Can you show me an example of this terracing?

Have you noticed the high tide level isnt that of previous as well? By how much?

Our house is single skin concrete blocks, with concrete poured in the voids and rebar running through the filled voids from inside the solid concrete foundation slab up through the wall to roof parapet height.

Whilst no building is proof against being on top of a M10, I'd say ours is pretty resilient in terms of walls/blocks being able to unilaterally collapse. It is so tied together that it moves like a giant cube - I think you could pick it up whole and turn it upside down to be honest!
