Christchurch until September 2010 had no known faultline near the city. Apart from the major Alpine fault line the majority of people are of course well aware of

A good article -

and here -

Sometimes, the cracking can be a new fracture, a flat plane of splitting happening for the first time, but mostly, and always in large quakes, the ground gives along already existing fault lines. A split slides a bit further to release its energy

A fault line about 5km long can generate only a magnitude-6 disturbance, a half-kilometre crack can produce only a 5, and a fissure of a few hundred metres will only ever give a 4.

Berryman says, the Port Hills and Canterbury Plains will be riddled with fault lines like this

The landscape may be peppered with subterranean fault lines, but there is a limit to how many can be of any real size. And from studying the bigger ones, we can make predictions of some confidence about what a city like Christchurch needs to be prepared for

Because Canterbury is such a huge dumping ground for the Waimakariri Rivers Silt deposits, its entirely possible that there could be numerous faultlines still undiscovered near Christchurch.

Hundreds or thousands of years of silt deposits and no visible sign of a fault line, but who knows what lies beneath.

Again you are not reading the information in front of you..

Sure the Greendale Fault and the Lyttelton (or it may be called the Port Hills Fault yet) were not known before, but to say that the Alpine Fault was the only cause of quake damage to ChCh before, is incorrect.
Take a look on Google Maps at where Lake Ellesmere is, it is no where near the Alpine Fault, it is in fact south of Darfield and the Greendale Fault
I guess everyone just forgot about this one.
There is no Fault shown on the NZ Faults Database for Lake Ellesmere, yet they had a quake with intensity of MM6 in 1870

August 31 1870, "Lake Ellesmere" earthquake The 1870 earthquake, on August 31 at 6:53 pm (local time) was more widely felt than the 1869 earthquake, with the highest intensities around Christchurch, at locations on Banks Peninsula and South Canterbury, but felt at least as far south as Dunedin, on the West Coast and North Canterbury. In Christchurch city, there was damage to household and shop contents as well as isolated chimney damage, e.g. one or two chimneys fell in Avonside, one in Chester Street and another in Papanui Road. The upper parts of several chimneys were rotated near the railway station. There was also isolated minor structural damage. At St John’s church in Latimer Square the stone cross fell, causing damage to several roof slates, and some old cracks opened in the stonework. Old cracks in the Town Hall also moved. The damage is consistent with MM 6 at most. Several chimneys, as well as household goods, were damaged at Lyttelton, about Banks Peninsula and in South Canterbury as far south as Timaru, the intensity not exceeding MM 6, except possibly at Temuka, and the eastern side of Lyttelton Harbour. The spatial distribution of intensities indicates an earthquake at greater depth than the 1869 earthquake. This is consistent with the reported longer duration of strong shaking, the occurrence of only one or two slight aftershocks and observations of the two shocks separated by a short interval that are almost certainly P and S waves.

New Zealand has long been known as the "shaky isles".

I do not see anything sinister in two tectonic plates smashing against each other.

Geological forces at work and coincidences.

take care all

Good links!

Yes rash indeed of me to use the words "no known fault lines near the city". I mean near as in really close to the city. Darfield in 2010 amounted to a distance of 40 km from ChCh. The Feb 2011 quake was virtually smack under the city. A bullseye. Just saying.

I concur while not being a specialist in the area, I defer to you. There are in fact likely a myriad of fractures in the bedrock beneath the alluvial plains of Canterbury, as many a good geologist has pointed out particularly since September 2010. That much is historical record anyway.

Certainly though the largest known fault considered to be a major threat to Christchurch as it is to most of the country is the fault between the Indo-Australian and Pacific plates running as it does along the Alps at its closest distance to ChCh. These two earthquake events the Darfield and the latest epicentre Lyttleton area have produced the most severest quakes any European settlement in Christchurch has suffered following the Hope fault originating quake of 1888.

My point is really this. Christchurch has never been considered as a major earthquake zone. No one before realized a fault of this kind existed beneath the city. There is no argument from me the precursors were all in place long before 2011, or 2010 for that matter.

The argument for scientists as best as I can make out is why now and why that particular location. To the best of my knowledge these events require the precursors to be present and then for some cause to trigger an actual quake. These are the kinds of answers I am looking forward to learning.

Good to have your input.

"Again"?? Gee. You are on my case. No, I am not saying that here at all.

Read my reply to GrantBeed above. That is what I am saying, and all I am saying regards historical record of quakes in ChCh.

I would also put it to you its a bit rash for you to suggest as you imply in that quote above, that the Alpine fault movement has nothing to do with quakes in and around ChCh past and present. I am not saying that. I am pointing out though that these (the 2010 Darfield centred quake and the 2011 Lyttleton centred quake) are new faults, and they were not known before the events.

I am saying also regards ChCh and shaking ground;
"Christchurch was not regarded in the Southern hemisphere as an earthquakes prone locality before September 2010. That this new fault has appeared suddenly and dramatically is startling."
This remains true.

Since you bought up the 1870 quake I have had to revisit this I have above.
"Christchurch until September 2010 had no known faultline near the city."
Te Waihora is only eight km closer to ChCh than Darsfeild. I correct myself here.

The article highlights the shallow nature of the February 22 2011 ChCh quake, the close proximity of the epicentre, and the unusual acceleration of the shock waves. This was an unusual quake even by tolerant standard of earth science.

Y'all can take the thread according to your interest in the topic. But would like to remind you in any case what it was at the top.

The topic is

It is possible somewhere on the planet earthquake event prediction techniques are so precise some vested interests knew and prepared for both of the earthquakes to further their own agendas

I would like to refine that to focus precisely on the 2011 quake. Although I see both quakes as being related in many ways apart from the affected location.

Here again are the points of the argument.
1. These two earthquakes are unusual because of features not usual in a 'typical quake'. Therefore they were not expected by locals. But were both quakes actually prepared for? Because that is what the thesis above implies.

2. The perfect storm for Christchurch. For all the reasons above the 2011 quake in particular hit ChCh very hard. It also hit the NZ economy hard! Consider in light of the thesis.

3. Just the right audience in the front row, and in the box seats in town the day of the earthquake. The coincidence of the particular conferences, the particular individuals, and the particular backup forces in town at the time of the quake are altogether too many coincidences.

4. ChCh is the perfect test tube / petri dish for a social experiment of the most opportune sort. One that is simply outrageous. I would like you to consider that in terms of the thesis above.

Finally, with reference to just part of that audience.
Here’s what one of the Congressmen, a 16th District Republican from Egan, who escaped the ChCh earthquake via plane was reported by his spokesperson to have said from Wellington in the hours following the earthquake.
The underline is by me.

He said it is absolutely devastating what is happening there,” said Manzullo spokesman Rich Carter. “He said it is kind of like their 9/11, their tragedy."
US Rep. Don Manzullo and 8 other congressmen flew out of ChCh just two hours before the quake struck! Lucky guys.

Agreed, i get what youre saying.

It certainly has the attention of all these scientists now, thats for sure. The big question is, "where has the most recent big quake shifted the pressure to?"

Wherever that pressure is, is the most likely place for another quake.

It's quite ironic that they are busy doin huge drilling tests on the Alpine Fault, yet the activity is 1.5hrs away on the plains!

or maybe they know something we dont!
