Ohau Point seals casualty of earthquake

A seal colony at Ohau Point, about 25 km north of Kaikoura, has been hit by a large landslide. It appears that this may have wiped out a creek walk and waterfall pond where many seal pups congregated and played. Fortunately due to the breeding season being not quite started there will have been few or no pups up the creek when the earthquake struck.

I went on the five minute walk up the creek in May. There were young seals dotted along the sides of the track.

At the end of the track is a waterfall fed pool. When I was there there were about fifty seal pups playing in the poll and lounging around on the rocks surrounding the pool and on the creek banks.

Stuff reported today: Famous seal breeding ground destroyed by quake

Ohau Point is a popular tourist spot due to its thriving seal colony on the jagged rocks by State Highway 1.

Visitors can walk along Ohau Stream Track to a waterfall, where seal pups are often spotted playing in the pool beneath.

Massive landslides caused by this week’s earthquakes appear to have wiped out the breeding ground along the coast, just weeks before the start of pupping season.

It is likely some seals were killed in the landslides.

It was fortunate timing, however, as many would have been out at sea feeding ahead of pupping season.

It was unlikely there were pups at the waterfall at the time of the earthquake, Morrissey said.

Someone posted on Trip Advisor saying they were at the waterfall on Sunday, the day before the earthquakes started.  Lovely waterfall but no seal pups on 13 November”:

The falls are located about 21kms north of Kaikoura on the scenic state highway 1 and, given we were passing, we stopped to check out the waterfall for seal pups. No pups, but the 10 minute walk to the waterfall was still worthwhile.

A photo from RNZ:

It’s unknown how the track, creek and waterfall are affected. It’s hard to tell from this photo, they could be underneath that rock fall, or they could be beyond it.

Unless the slip is hundreds of metres wide the creek may be on the far side of the rockfall.

Alternate route to Kaikoura coast?

Andrew Little has asked whether an alternate route should be considered after the Kaikoura cost road has been extensively damaged by landslides and slips after Monday’s earthquake.

1 News: ‘We need to think of an alternative route’ – Andrew Little questions whether repairing damaged road is worth it

Roading and rail along the coast is certainly a huge challenge, but I don’t know how much Little has thought about alternate routes.

That corner of the South Island is a mangled mess of mountains riddle with earthquake fault lines.

Mangled mess of mountains

That whole area has an estimated 80,000-100,000 landslips, and inland is more mountainous, especially north of Kaikoura.

Which of these fault lines would an alternative route be better? All valleys follow fault lines.

That is before this week’s earthquakes which are scattered across the region.

Warship protests

Auckland Peace Action has planned a protest against warships visiting Auckland.

website-header-new2

Flotilla time change

NOTE DATE CHANGE!
All Navy boats arriving Wednesday 16 November in groups of 4 from 5am – 2pm with a gun salute at 11am. Please feel free to go out on the water to protect the peace from these warships.

The planned peace flotilla has been postponed:
We will be meeting from 12.30pm in the harbour and surrounding the navy ships that will be lined up there, stationary, from 12.30pm-2.30pm. Navy event details here: http://nznavy75.co.nz/international-naval-review/

This flotilla is part of the ‘Week of Peace’ – a series of organised public demonstrations to challenge the business of war and send a message that peace is not just the absence of war, it’s something we must work actively towards. Please join us on the water – if you don’t have a boat, find someone who does to take you out, or borrow a kayak!

The Daily Blog has tried to make this an Anti-Donald Trump protest as well.

Do you hate Trump and want to show it? Then protest the American warship visiting Auckland this week

So are you shocked by the Trump result and the magnitude of political and social carnage he is about to wreck upon the planet?

Then protest the American warship that is visiting Auckland next week.

Rage against this ugly mutation of Western Democracy by protesting against the American Warship visiting Auckland next week.

Trump isn’t president yet so making it an anti-Trump protest seems a bit of a diversion, or opportunism to protest at anything on whim. That was posted before this week’s earthquakes.

Now the ugly mutation of Western Democracy and others are using their warships to help in Kaikoura.

Fleet of international warships to help out with earthquake response

A fleet of international warships are bypassing Auckland’s historic naval celebrations and heading for Kaikoura to assist with the earthquake response.

They include the first United States warship to visit New Zealand in 33 years.

The USS Sampson was due to enter Auckland Harbour tomorrow morning for the International Naval Review as part of celebrations for the 75th anniversary of the Royal New Zealand Navy.

The USS Sampson, an Arleigh Burke-class destroyer, has departed from the Hauraki Gulf and is now on its way to Kaikoura, where it will deploy two MH60 helicopters to help as required. The US has also offered a P-3 Orion for surveillance flights,” Brownlee said.

The Australian Defence Force had diverted the HMAS Darwin from her planned participation review.

“The Darwin is expected to arrive off the Kaikoura coast on Wednesday evening and will deploy its Seahawk helicopter from offshore. Canada is sending its frigate the HMCS Vancouver.”

Brownlee said the New Zealand Navy had already sent HMNZS Canterbury and HMNZS Wellington to Kaikoura and would also send HMNZS Te Kaha and tanker ship, HMNZS Endeavour.

The New Zealand Navy is something some activists and parties like the Greens want to do away with.

Ships of war are often used in peaceful emergency roles as well as trying to help prevent wars.

Being able to protest is an important part of a free democracy.

Perhaps activists doth protest too often, to be effective you need to choose your battles wisely. In this case a natural disaster has rendered their Auckland protests a bit pointless,  especially with the warships being used to do some good.

War and peace is complicated.

Earthquakes – Wednesday update

The earthquakes are continuing, now generally fewer and smaller, often seeming in pairs near Seddon and Kaikoura, and at times in triplets with Culverden/Cheviot/Hamner Springs in the mix.

Geonet had an update at 4 am:

  • 23 earthquakes located in the last hour (Wednesday morning)
  • 278 earthquakes since 6 pm (Tuesday)
  • 1,492 earthquakes  since the M7.5 Kaikoura Earthquake (just after midnight on Monday).

Alan was in Hamner Springs when the M7.5 struck:

I was in Hanmer in a wooden Fraemohs chalet trying to fix my phone while my wife watched a TV movie when the first big 7.5 hit. I have to say the chalet was great – strong as a boat in a storm as we rocked and rolled. It was built on a good thick concrete pad and the interlocking beam walls performed perfectly.

We had driven through the epicentre at Waiau that afternoon and stopped for a few minutes of course never guessing anything so drastic was about to happen there.

While it was happening I was standing back to a window which in retrospect although it had a heavy curtain was probably not a great idea but it was too far to get around the bed to the passageway while keeping my balance while it was like being on a yacht in a choppy sea with a howling wind.

The noise was like a train or a plane roaring past right outside.

I have heard people from Christchurch describe the bigger earthquakes as like a train roaring past right outside their house. I’ve never been close enough to a big one to hear one (I’m not complaining).

After that I could hear the aftershocks coming as a low frequency sound just before they started but my wife couldn’t. She hears higher frequencies better than me though.

Power went out in the middle of the quake and didn’t come back till midday the next day but the road out didn’t open till 4pm the next day.

Alan was lucky the road was openable. One of the remarkable things about these earthquakes, presumably mainly as a result of the huge M7.5, is the widespread destruction of roads – not just the huge slips on the Kaikoura coast but so many roads have been ripped apart, like this one in Waiau.

state-of-road-in-waiau-after-earthquake-supplied

There have been many movements of land, ripped apart, buckled and raised and lowered.

kaikouraseabedraised2

Aerial photographs show the seabed uplift north of Kaikoura – estimated to be between 2 – 2.5 metres – more at @TonkinTaylor – which also shows minor road slips.

Media seemed to obsess over the trapped cows yesterday morning – they were rescued – but now the poor paua are being pitied, raised out of the water and dying.

Newshub: Baby paua suffering terrible deaths in sun

It’s not just the thousands of exposed paua that are a high concern in Kaikoura – exposed baby paua are also dying by the hour.

The paua have now been exposed out of water for more than two days after the seabed was lifted nearly two metres out of the water by Monday’s 7.5 earthquake.

Paua Industry Council’s Storm Stanley says there’s a lot of worry for the tens of thousands of adult paua but people forget about the babies.

“What you won’t see are the smaller paua that live under rocks. They live under rocks until they’re about 16, 17 millimetres long before they come out again,” he says.

pauaraised

Nature can be brutal.  It’s tough on the paua and other exposed sea life on the fishing industry, but I suspect there are more pressing problems for most people to attend to.

RNZ have today’s key facts:

Rescue efforts in Kaikoura continue as helicopters and NZ and US defence force ships head to the quake-hit town with supplies.

Wellington is also dealing with the aftermath of Monday’s 7.5 magnitude quake, with a city centre building at risk of collapse.

As usual they are covering things extensively – see RNZ continues live online coverage here.

Damaged buildings in Wellington is becoming a big story of it’s own – that’s for another post.

Non partisan survey of earthquake areas

It was good to see Andrew Little accompanying John Key and Gerry Brownlee via air force helicopter to survey the earthquake damage in Marlborough and Kaikoura.

The repair work of infrastructure and especially roads and rail lines is going to be an expensive and long term project. Understanding the scale and cost of the problems by both major parties is important, and cooperation in planning the repairs, is going to be important.

Either Key or Little could be leading the Government this time next year and there will be a lot to do still then,

The cost of repairs, roughly estimated at several billion dollars, will impact on the New Zealand economy and Government budgets, and party policies heading into next year’s election will have to take in account the impact of earthquake repair costs.

From Stuff: Kaikoura earthquake: PM surveys the ‘devastation’ from the air

The Prime Minister says the damage to the Kaikoura region is worse than he thought.

Massive slips could be seen as he flew over in a Defence Force NH90.

“It’s just utter devastation, I just don’t know … that’s months of work,” John Key told Gerry Brownlee and pilots.

Dust billowed down the hillside as the chopper circulated. The pilot said he’d never been airborne when a quake had hit before.

Key asked how big the quake was but the pilot didn’t know.

As they flew over Key and Brownlee commented on the damage to rail lines and roads.

The doors were opened and the helicopter flew low as Key, Brownlee and Andrew Little surveyed the area.

As he viewed the damage, Little said the mudslides and rockfall were “stunning”.

“I can’t imagine what it will be like to clear it,” he said.

“Look at that road down there, it’s been hammered,” Key said.

A slumped hill could be seen and Brownlee commented “oh hell that’s amazing”.

A non-partisan appreciation of the scale of the problems is important, as will be the plans to fix the damage.

Just one of a number of major slips (there have been estimates of up to 100,000 slips throughout the area):

Massive problems – and both National and Labour along with the other parties in Parliament will need to work constructively together on funding and planning solutions.

Earthquake – update information

Key facts from RNZ:

  • A 7.5 magnitude earthquake struck near Hanmer Springs at 12.02am on Monday.
  • There have been two confirmed deaths. One person died in a house that collapsed in Kaikoura, and a second person died at a house in Mt Lyford, inland from Kaikoura.
  • Scores of severe aftershocks have hit.
  • Kaikoura is still cut off from the rest of the country, with major landslides blocking the roads in and out.
  • Six people suffered moderate to serious injuries in Kaikoura and were airlifted to hospital; another 18 were treated for minor injuries.
  • Most of Wellington’s CBD will open as normal on Tuesday morning, with parts of Featherston St cordoned off.
  • People living near the Clarence River were told to evacuate after a dam breach. A group of kayakers, and another group of 16 rafters, have been found safe.
  • Tsunami warnings have been cancelled, but people are advised to stay vigilant near coastal waters.

Morning update (Tuesday 15 November).:

  • Mass evacuations are due to begin this morning from quake-hit Kaikoura, on the South Island’s east coast.
  • The town is cut off by road and rail, and the navy ship HMNZS Canterbury has been sent to help bring supplies and get people out.
  • 1200 tourists are believed to be stranded in Kaikoura, and RNZ News has been told as many as 50 helicopters will also help evacuate them.
  • Large aftershocks have continued to rattle buildings and nerves overnight in the town of about two-thousand people.
  • Civil Defence says only three days’ supply of fresh water remain.
  • The Takahanga Marae deputy chairperson, Major Timms, says the town’s concrete water tank has split in two. The marae yesterday fed about 700 people in the aftermath of the quake and is expecting large numbers again today.
  • A team of specialist engineers will begin inspecting earthquake-damaged buildings this morning.
  • The Civil Defence national controller David Coetzee (could-seer) says about 50 buildings in Wellington need further assessment. And the engineers will also carry out assessments of several buildings in Kaikoura. Mr Coetzee expects it will take a couple of days to get a complete picture of the extent of the damage.

Wellington:

  • You may be able to head back to work today, but you should check with your boss to make sure you can go back to your building – and use your commonsense.
  • Commuter rail services in Wellington are expected to return to normal schedules today after yesterday’s quake related suspensions operator Metlink says.
  • The capital’s bus services are running but are diversions are in place in the central business district  to allow inspection of buildings for quake and wind damage.
  • The Fire Service says there were no major callouts in the capital overnight although Civil Defence said there were some instances of broken glass being dislodged by last night’s winds.
  • Some areas of the CBD remain cordoned off due to the risk of further glass and debris being dislodged by strong wind.
  • Civil Defence says Central Wellington will be open for business today  but people will need to use their commonsense and check with their employers whether their building has been inspected and deemed safe to enter.
  • A KiwiRail spokeswoman said two freight only Interislander ferry crossings of Cook Strait were made last night but passenger services were yet to resume.

Earthquakes continued…

Quakes have continued to rumble through the night in the north east of the South Island, with 28 recorded at Geonet in the last hour (4:20 to 5:20 am). There have been about 800 aftershocks altogether.

There are reports that there could be up to 100,000 landslides/slips.

Geonet says that multiple faults have ruptured:

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 

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.

‘Strong’ or ‘severe’ quakes overnight (these seem to have slowed down):

  • 5.0 (severe) 10:49:56 pm 10 km east of Kaikoura
  • 5.1 (strong) 12:16:42 am 15 km east of Seddon
  • 4.8 (strong) 1:03:00 am 5 km west of Kaikoura
  • 4.6 (strong) 4:22:19 am 10 km east of Seddon

So both Kaikoura and Seddon continuing to bear the brunt of this. Those are moderate sized quakes on the scale but they are shallow (8-25 km) so more energy gets to the surface than deeper quakes.

This map shows the pattern of quakes since midnight yesterday. Most of them are shallow.

And this shows their strengths better:

M7.5 Kaikoura Quake: What we know so far

Updated at 23.52, 14/11/2016 This earthquake was the largest recorded in New Zealand since the M7.8 Dusky Sound earthquake in 2009. But, given its location, it was more widely felt and more damaging. This earthquake unsettled many people and that is perfectly normal; earthquakes can be upsetting events. The best advice we have is to be prepared for earthquakes.  We can say one thing with certainty: there will be more earthquakes to come in this area.…

M7.5 Kaikoura Earthquake: Latest updates

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.

We’ve developed three scenarios based on what we know so far but be aware that our understanding is evolving as we do more analysis and receive more data. 

Scenario One: Very likely (80% and greater)
A normal aftershock sequence that is spread over the next few months to years. Felt aftershocks (e.g. M>5) would occur from the M7.5 epicentre near Culverden, right up along the Kaikoura coastline to Cape Campbell over the next few months to years. This is the most likely scenario.

Scenario Two: Likely (60% and greater)
In the next month, it would be likely that rupture of earthquakes of about an M6 in the North Canterbury and Marlborough regions will occur, as well as potentially offshore in Southern Cook Strait and offshore Kaikoura.

Scenario Three: Unlikely (less than 40%)
The least likely scenario is that in the next month, (it is unlikely but still possible) there would be rupture of longer known faults (with earthquakes of about M7), in the Marlborough and Cook Strait regions.

So there is at least likely to be a continuation of the many aftershocks, with the lower possibility of some quite large ones still to come.

South Island highways update

It’s fairly obvious that State Highway 1 along the Kaikoura Coast is severely munted and will be closed for some time – this is just one of a number of slips…

1479092228151665

…and there are many fault line cracks and breaks breaks as well like this…

earthquakehighway

…and worse.

A detour is now open between Picton and Christchurch (with some restrictions) via Murchison and Lewis Pass. Here is an update on highways from Land Transport.


South Island highways update – 8:15pm Monday 14 November

NZ Transport Agency contractors will resume work at first light tomorrow to assess the safety of key South Island state highway routes and continue clearing slips to safely re-open roads as conditions allow.

An alternative inland state highway route was re-established earlier today between Picton and Christchurch, via Murchison and the Lewis Pass.

NZTA contractors worked urgently throughout the day to assess the safety of bridges and clear slips to safely open the route, re-establishing access for communities and allowing large trucks through to Christchurch.

While the route is open, the NZTA is advising that some sections will only be open to a single lane, with active traffic management in place. Motorists are urged to use caution and take extra care as conditions are still changing.

Transport Agency Highway Manager Neil Walker says a top priority for the Agency will be undertaking a detailed assessment of the scale and complexity of the large slips which are blocking SH1 on either side of Kaikoura.

The Transport Agency is working urgently with Kaikoura District Council to open the inland road (old State Highway 70) between Culverden and Kaikoura. Work crews have been assessing the road and structures for damage today, and crews will do everything possible to have this route safely open within days.

State Highway 1, Picton to Blenheim/Seddon is now open but Seddon to Cheviot remains closed. Cheviot to Christchurch is open.

In assessing sites blocked by large slips, the safety of the public, as well as Transport Agency staff and contractors is paramount, particularly with the possibility of continuing strong aftershocks, along with forecast high winds and heavy rains.

The priority is to re-connect communities which have been cut off by slips and the Transport Agency is working urgently with other agencies such as Police, KiwiRail and local authorities to coordinate efforts ensuring that people are transported out of closed areas safely, and roads or alternative routes are open and safe to use as soon as possible.

Transport Agency Highway Manager Neil Walker says it is too soon to tell how long it will take to assess the damage on all the upper South Island highways in order to open routes, or open up safe detour routes.

“Some have already been assessed and work has been planned for some sections of the highway with less severe damage. Other sites are currently inaccessible by road and/or 4WD and the safety risk needs to be carefully managed both in assessment and in the emergency repair work itself. Transport Agency and council teams are working as fast as we can to reopen highways or find alternative routes to places like Kaikoura.”

“Our priority is gaining access to communities which have been cut off, and also establishing an alternative route north from Christchurch to Blenheim. State Highway 7 is open, providing an alternative route for traffic to travel north to Blenheim. Drivers need to be cautious as the route will be down to a single lane in places. This alternative route will take approximately three extra hours, so people need factor in a longer journey time into their travel plans and ensure that they have plenty of fuel, warm clothes, food and water.

State Highway 7A, giving access to Hanmer Springs from State Highway 7, is closed overnight due to the risk of further rockfalls, and will re-open at 7am tomorrow for light vehicles only, and under escort by contractors. We will reassess this route during the day on Tuesday.

The Transport Agency thanks all road users for being patient as many people’s travel plans are disrupted and many people are again managing their homes, work and lives amidst the aftershocks.

People can call 0800 44 44 49 for updates and the Transport Agency’s website and social media accounts will be also updated as more information is available.

South Island updates

Wellington updates

Mass of quakes continue

When I headlined Earthquake onslaught  that was based on what had happened in the few hours since the 7.5 quake just after midnight, but things haven’t let up all day with hundreds of quakes around the top half of the South Island.

The quakes have often been in clusters alternating between Kaikoura, Seddon and North Canterbury, with a few outliers.

There have just been two more ‘severe’ shakes amongst a cluster:

  • 3.6 (light) 7:37:16 pm 25 km north-west of Cheviot
  • 3.6 (light) 7:38:13 pm 10 km east of Kaikoura
  • 3.4 (light) 7:40:54 pm 35 km south of Seddon
  • 5.6 (severe) 7:43:01 pm 25 km east of Seddon
  • 4.4 (moderate) 7:43:34 pm 15 km north-east of Methven
  • 5.7 (strong) 7:47:51 pm 25 km east of Kaikoura
  • 4.3 (strong) 7:51:58 pm 15 km east of Seddon
  • 4.5 (strong) 7:52:53 pm 20 km east of Seddon
  • 4.4 (light) 7:55:44 pm 35 km east of Kaikoura
  • 3.6 (light) 7:56:19 pm 15 km east of Levin

That’s 10 in 20 minutes. The whole area seems to have become unstable.

And the pictures being published of the roads, railway line and hills shows how unstable the area is on the surface. Huge and smaller slips have blocked roads and lines in many places. It could take weeks if not months to open state highway 1 between Picton and Christchurch reopened.

1479102755741649

Kaikoura is cut off due to major slips both to the north and to the south.

1479092228151665

There was a road and a railway line round here yesterday. And paddocks and stock have also been affected.

cxmab-uusaeqekx

There have been two deaths reported. Given the size of the quakes this is relatively low, fortunately being in the middle of the night in mostly sparsely populated areas helped minimise casualty rates.

But there are many ongoing aftershocks, quite a few fairly strong, and Geonet says there’s a 32% chance of another 7+ in the next month or two.

There have already been six quakes rated as ‘severe’ today, near Culverden, Kaikoura (3), Seddon and Cheviot. There was widespread minor-ish damage in Wellington and they ‘only’ had a 5.3.

What has happened already will have a major impact on Marlborough and North Canterbury and also further down the highway. The alternative routes by land are lengthy, via the West Coast.

And there will understandably be many worried people.

There’s enough cause for concern down here in Dunedin (where some people were woken by the big midnight shake but I haven’t felt a thing) having seem the enormous effects on Christchurch.

There will be many frazzled nerves after a day of sustained shaking in the top half of the South island and the lower North island.

UPDATE: since typing the above list and the rest of the post there has been another  ‘severe’ (5.9) and another ‘strong (5.8) quake near Seddon – they are 30 seconds apart so must just about be the same quake.

Earthquake onslaught

There has been a mass of earthquakes ranging from North Canterbury to the Wellington region, with the biggest ones near Culverden (7.5), Kaikoura (two at 6.2), Seddon (5.3), Wellington (5.3)  and Paraparaumu (4.9).

So far there have been 27 quakes rated severe or strong since midnight.

earthquakes2016-11-14

‘Casualties’ have started to be reported:

Police say one casualty has been reported at a collapsed property in Kaikoura.

Updated – two confirmed fatalities so far.

There was a tsunami warning and 2.5 metre waves were recorded at Kaikoura but that has now been downgraded.

Aftershocks are continuing, and damage is just being assessed in many areas as daylight breaks.

Many roads are closed. Photos are emerging of widespread road damage. A slip has blocked a rail tunnel and the twin road tunnels on the Kaikoura coast road. And the Waiau River bridge may be damaged – this is the main access to Hamner Springs.

The Cook Strait ferries have been stopped and crossings have been cancelled. The passenger bridge in Wellington has been damaged.

Wellingtonians have been advised not to come to work today. Damage in city extensive

People are being advise to stay out of the Wellington CBD until damage has been assessed.

And gale force winds are forecast for central New Zealand today.

The per-year movements are averages, the actual movements tend to be far less frequent and larger.
