7.0 earthquake hits Christchurch, New Zealand

reply to post by aorAki


I just prefer the answers from our own guys, who are on the case all the time, rather than some USGS "experts" who just happened to be here on holiday.
I'm sure Furlong means well, but on the Sainsbury TV1 show after the News the other night, on the fault site visit I got the impresson from the body language of the two other geologists that they wished he'd just bugger off and let them get on with their measurements

Absolutely ! By a foot or so

Before the Plains were there Banks would have been an island . Even Captain Cook thought it was an island back in 1700 odd.

You know that Dunedin harbour is a caldera also?

I haven't been saving them. Perhaps our friend Puterman can lift some of RPZ or MQZ if they are part of the SNZO network. I'm pretty sure RPZ (Rata Peaks ) is part of it, they show on the Phase data for most pacific quakes.

Yep, I've been watching Rata Peaks and McQueen's. In fact, if you overlay Rata on McQueens it's almost like Rata is showing trigger event and almost instantaneously McQueen's answers.

Yes, knew about Dunedin - volcanoes are also on my list of passions/watches LOL along with storms!

Yep, as I said in post above - the gap between Banks "Island" and S.Island covered over by sands and alluvial deposits...

Must be a connection there with these faults, but you'd think they would have factored in this sort of geological stress/action if they know Banks and S.Island moving apart?

Canterbury has received 270 aftershocks of magnitude 3 or above so far since Saturday's destructive 7.1 earthquake, according to GNS Science.

This mornings aftershock was devastating emotionally. The emergency centre had to evacuated as power went out, sent many crews back onto the streets. It made so many workers break down. I can tell you all around the world, we are on our last limbs. We're gonna keep fighting but for how long we do not know. The aftershocks seem to be getting rather shallow, it would really damage us if the 6.1 we're waiting for occurs now and at such a low depth.

Yesterday on the news, they reported that it would be one earthquake of about magnitude four a day by next month. Its a miracle nobody died but that may change with the coming days. I hate to sound negative but its the bitter truth.

Keep us in your thoughts

You hit the nail on the head there re each time another big (5+) hits it is emotionally devastating. Both times I decided to brave going to bed last night another 4+ hit and nerves jangled again...

Trouble is, we're still only a few days out from the big one and I'm sure those that know little about aftershocks/quakes still believe they should just be stopping and don't realise how long we may have to go through them.

My fear has begun to turn to defiance - I now wait when the house shakes and count to 5 if it's still going I get down in my prepared void space and wait..

One huge downer here is that they have started running the coal train again from Greymouth - here in Waddington it goes near our house and it sounds JUST like the noise at the start of the first big aftershock.. sets my tears off on occasion and even my brave hubby (who has been my rock through this) gets teary.

You and I will have to disagree on why TVNZ picked a visiting academic over a local one. When I say local I mean WORKS locally. I've seen the same shenanigans over Chemistry and Biochem (I hold a PhD in the formed, and a Masters in the latter) when they need an "expert".

I understand you are on edge, but I can be subjective down here thanks. There was no reason that the media could not have gone with someone local. Beyond this guy was at the epicenter, on the day, looking interested. At least they had Civil Defense locally, rather than asking someone say in CA.

...but he is an expert in his field (I assume you mean Kevin Furlong?) I would rather have an expert's opinion even if he wasn't from around here. He knows as much about this earthquake as anyone and is no one trick pony. Mark Quigley works at Canterbury University and is the local authority even though he's Canadian so he's 'kosher' aye.

There is a big difference between asking Civil Defence here and in Ca because the responses are different. Regarding the geological interpretation, Kevin has been here for 6 months and has engaged in prior research around these parts. We are lucky to have some of his standing able to comment so knowledgably.

geodynamics research

Yeah, I'm really annoyed that he took all the limelight from a local. He's so petty like that.

Yes, I am on edge, but it doesn't mean I'm not subjective. I'm not hung up on the 'local' factor and appreciate that the media had someone so well-versed to turn to.

Geology is a field where much collaborative research is undertaken and people go all over the globe following their research interests.
"Our own guys" aren't on the case all the time. They have research interests elsewhere as well....and, don't forget professional rivalry, and certainly the IGNS scientists, while excellent at their work can and do suffer from this as well.


In short, who bloody cares as long as the correct and vital information is gained?

Truely i hope you both stay safe. I have friends who think the worst is over. I sincerly doubt the worst is over. I have a horrible feeling that their will still be a considerably larger quake than a 6. But thats just me. If you need help or anything please send me a message and i'll see if i can help.

I hear you. We have a similar effect with cars/trucks at times. It's damn unnerving because the noise is so similar.

Semoro, you might find this useful

...and likewise for help, message me and if I'm of use and available...

I agree. I didn't want to say that before, because I know many think it's scaremongering, but I have the same feeling. This fault/quake is so unknown I don't think anyone can make a call, but my gut is saying this is the start of something bigger. Perhaps that's my way of coping.. I don't know... all I know is that I am not resting on my laurels or pretending this is going away. I've been told to "get over it" and to "stop monitoring them it'll make you feel worse". Well, we all cope in different ways and my way has always been to keep informed and stay alert and expect the worst.

Many thanks for your kind offer and, of course, the same goes for you and Aoraki and anyone else out there on ATS in Canterbury who needs help or even just an online chin wag..

Stay safe all x

Aoraki - that fault you were surveying through Waddington / Sheffield - does that come into play in this? I ask because it runs 100m from where I sit now, parallel to my fence line!! Hence why your depth chargers set my dogs off!

I know what you are saying. We are not that far from the Airport and every time a 747 fires up it sounds like another quake coming.

Bloody terrifying!

...Yeah, apologies for annoying the dogs.

um, the short answer is I don't know. I suppose there is the possibility but try not to entertain that until we can get an official response.

All we can do is be and stay prepared.

Not sureif anyone picked up on this from TVNZ News -

2:20pm: There have been reports of sulphur smells in parts of Christchurch. Firefighters and Environment Canterbury's Hazardous Substance team have been investigating the smell.

They say at this point there's no indication it should be of concern to residents.

It does not appear to be a gas leak

tvnz.co.nz...

Many accounts of Sulphur smells before major quakes thrughout history. Lets hope it's an "after quake" smell and not a "before quake" smell.

I'll be fine. If you live close to the airport, you must live close to me, Bishopdale? I do hope that the big ones will occur before school begins. The stress isnt why, its just my family and neighbours and lets face it, lack of sleep

Do you think the mainstream media is trying to avoid bringing up the possibility of a bigger quake? I just think that its kind of odd that they have not. Its relevant to our survival. Has anyone else heard the rumours of QE2 being condemmed? Apparently they lost 80,000 litres of water and a large crack in one of the pools. Could be wifes talk, so just asking.

Stay safe all. And yeah i would love a chinwag if its all good (: Message me the details. Same goes to any resident of Christchurch or abroad.

Sulphur smell' reported in Christchurch

www.sbs.com.au...

My guess is that as a result of liquifaction lots of anoxic sediment has come to the surface.
Same smell as when we did a sand profile of the estuary last year.

Its Good to see people offering help to each other,onya mates,good to see the human spirit come alive when times are tough,God bless

Thank you for posting that Christchurch quake map I have never seem one like that before, it is very handy.

I am noticing that in the last past hours the quakes are getting smaller in the 2 range instead of the 3 and 4-5 range.

I hope things are starting to settle down and stay settled down for all of you.

I can't even imagine how you are all handling this it has to be very frightening.

My thoughts, heart and soul are with you all.
