Christchurch quake; widespread luting

The poor woman's been reading too much Dan Brown, going on about the illuminati, I didn't realise the Queen was a member! I particularly love this passage
"I know the NASA is a quasi-paranormal, hyper-scientific research Illuminati U.S. org who have persistently involved themselves in occult SPACE RITUALS, to help bring in global Luciferianism.

So New Zealand must have been chosen to be shaken by a HAARP induced earthquake by the hyper occultic British Royal family based on it being a place of magical energies."

& here's me thinking it was something as mundane as a couple of tectonic plates rubbing each other up. Ohhh didn't realise I was part of a 'magical energy' either! Must be all them little Hobbitsis we have here Laughing

# Reference Number: 3372745
# NZST: Thu, Sep 16 2010 7:24 am
# Magnitude: 3.5
# Depth: 7 km
# Details: 10 km north of Christchurch

That's right under Kaiapoi....not good.

The aftershock pattern strongly suggests that there's a system of active faults running under the city out into Pegasus Bay.

It also appears that the foreshocks that happened immediately before the main quake actually happened on faults closer to the alps (Hororata)....these quakes may have had a triggering effect on the "new" system closer to the city.

The Art Centre looks like its copped alot of damage....theyve had to cut down a huge ginko tree in the quadrangle to get a crane in to work on the old chemistry building.

Martin, why does that sound like this is just the beginning of things?

[Dennis Leahy]

Hopefully, this means that a lot of pressure was released, and that it will lower the chance of another major quake in the next _______years (hope that number is high.)

Still the threat of a big one hanging over our heads Dennis, I think many breathed a sigh of relief thinking we'd made it through "the big one", Martin's lot have been telling/warning us about, only to have them turn round post quake and say "That wasn't it". These recent quakes have been occuring along smaller faults perpendicular to the main fault which runs slap bang through the middle of both islands, so we still could look forward to that one 'springing' even in my lifetime.

Had at least 4 aftershocks (still) in the 4 - 4.5 range overnight & all within a 20km radius & at a shallow depth (6-10km depth). Experts are saying that with the current pattern (typical of most quakes) that the chance of another big wobble (in the 7 - 8 range) in the near future is remote but not ruled out.

Nick,

Anyone who categorically states that another large aftershock is impossible is dreading on dangerous ground. It's all about probabilities......as time goes on probability of a large (>5) aftershock decreases.

What you're seeing is a stress regime that's being relieved along more than one fault system. This in itself can be regarded as a good thing....the stress being relaxed along several fault systems rather than along just one. If the foreshocks hadn't happened then its possible the main quake could have been bigger.

If you want to find out more about all this then read up some of Jarg Pettingas papers. Jarg I think is now either HOD or associate HOD in the Geology Dept at Canterbury. He did a paper in 1998 for the Canterbury Regional Council which covered the fault systems under the Canterbury Plains.

I know Jarg. He was acting pro-vice chancellor for the college of Science for a brief term last year (until a permanent was appointed) & during that term I was on a committee to select a new HOD for Chem with him, nice bloke & he is indeed the current HOD of Geology.
That sounds like a paper worth reading, since this wobble I've been interested in learning more about the ground I'm standing on! Up until now I've only been armed with a rudimentary knowledge of the make up of the plains from High School geography (Alluvial flats, Greywacke rock e.t.c). I've also dug up both volumes of "The geology of New Zealand" NZ geological survey, editor RP Suggate. They are old (but I suspect so is the geology of NZ so would still be relevant today! Wink), a mate was chucking them out years ago so I grabbed them then just out of interest but never got to turning a page in anger.Always had a fascination with this sort of stuff & weirdly, I've always enjoyed reading manuals, references & textbooks rather than fiction! Rolling Eyes Should I be wearing an Anorak & open toed sandals with walk socks?


Well here's an unusual side effect Shocked

Pat Suggate was at the NZ Geological Survey in Lower Hutt when I was working there. A gruff old character but he was the pioneer in coal classification and very much part of the pioneers of NZ Geology along with von Haast and others. I got to meet alot of these guys during my time at the survey and got to work with a few of them in the field. Malcolm Laird was great to work with.....I think hes still lurking around the Canterbury campus.

For a good introduction to NZ geology there are more modern books than Suggate. I saw a couple in the book shop at The Arts Centre and the Uni bookshop should have a few.

Don't think I can get near the Arts centre at the moment until the structural engineers give it a clean bill of health. Crying or Very sad

Here's an oddball story from Chch. An Engineer attacked with a digger.

Ahhh good to see the Christchurch temprement is returning to normal, so far we've had people getting their abandoned houses burgled, a guy shot in the face by a "yoooff" weilding a gas powered pistol & now this. Unfortunately as the city gets back into looking 'normal' people are forgetting the community spirit that pervaded during the first few days 'post quake' (& we were congratulated on by many around the globe) & are slipping back into their old impatient & selfish ways Crying or Very sad.

Three big aftershocks in quick succession tonight....all centred under the city. Nick you'd better go back to sleeping in your clothes mate.

Ummm already on it Martin Mad , damn things & they were all around the 4 mark. I'm getting a little blase about the night time ones now, if they wake me (they have to be in the 4 range before I stir!), I usually just open one eye to see what the time was & think "I'll look that up on Geonet later" then go back to sleep. Some of the guys at work are playing magnitude bingo too.
The Press reported yesterday that as of Friday we've had 1189 aftershocks, this fault better de-stress shortly, there are a number of people (One of my daughters among them, poor thing is waking even if a heavy truck goes past her flat now) that are suffering from sleep deprivation & are getting either a little 'testy' or freaked out.
Has your father settled into alternative accomodation OK ?

Nick,

The destressing isn't just happening along the Greendale fault .....its a regional thing where stress is beng relieved along quite a few fault systems.

I see Bexley residents are planning to sue the Council for letting developers go ahead with the housing development there against advice of engineers/geologists. Good to see the cozy deals between developers and councils about to get busted wide open.

It would be nice to get these 'deals' exposed but I somehow doubt if Joe Public will get to hear the full story. Although we have local body elections happening now so hopefully alot of the councillors that have done very nicely out of these deals will not get voted back in & they won't be in a position to hush things up. But unfortunately they are well know faces whilst the hopefuls aren't, so I suspect people will typically vote for the familiar, even if they are a thieving pack of selfserving @**#heads, even the too smooth Bob the knob.
