That's a bit scary Ian. Greetings Berend

Ian Stehbens on April 28, 2011

My heart leaps and my stomach tightens even as I look at it now, Berend and my main flashback is to a 5.2 aftershock that gave us all a fright.

When the land moves this much, tearing a whole country apart it is a serious quake. And before this no one knew of a fault line here, partly because of the great overlay of outwash material from past glaciation.

You may also note that the line of trees that includes the stumps of those that have had to be cut down, was formerly straight too.

Greetings from Brisbane,

Ian

I really admire the courage of the inhabitants Ian, I am sure I couldn't sleep a single night if I lived here....

Ian Stehbens on April 30, 2011

Many found sleep difficult for many nights, and any sound or shake would cause people to start. In the end exhaustion takes over.

Even for us who were only minimally affected by aftershocks (not being there for the main quakes) any vibration reveals how hyper-alert we are - "What was that?" And if it is a tremor, then the question "Is this a prelude to a bigger shock in a moment?" "Do we do the 'turtle' or get out?"

It really is special to be able to chat with you, Maja.

The three pictures scary me too.

Warm wishes from Greetje

Hi Ah-Pong,

The road has been repaired but after the quake the white centre line was lined up with the white side line on the road, here. The 4M displacement continues acorss the lamndscape for kilometres. Powerful indeed.

Regards,

Ian

Dear Greetje,

Earthquakes are scarey, especially when they continue with periodic large aftershocks.

Thanks for visiting and considering these images of Christchurch's disaster.

Yes, the shakes continue today.

Mind you, we have only had a few more than 5000 since 4 Sept 2010.

So if you tally them up at about 5000 by about 240 days that is only 20 per day...

When a aftershock occures 30km away from my place, I are unlilely to feel it, unless it is more than M4.0 and also is very shallow in depth.

So, I'd only know about them when I look at the http://www.geonet.org.nz/index.html web site, or hear about it on the radio or TV, or talk to somebody who lives near that location.

Now, in the past eight months I have not missed a single night sleep, even if I did have a few nights where I had only 4 or 5 hours sleep.

Sometimes we get woken up after midnight with a ground roar or rumble, followed by shaking of the bed and house etc... but that is something most of us are getting used to.

Unless it is a good shaking M3.5 we often do not notice it. Sleep peacefully, we do! most night

I have slept through a M4.5 at just before dawn a couple of times.

Only when I check on the internet, at web site above, then I see that I've _ missed! _a good one...

(Not really!!!)

When we had a cluster of shakes on 26 Dec 2010, it sure stopped the Boxing Day Sales - as the epicentres were all in the Central Business District.

Out at my place, the place shook, trees outside swayed more than a metre to each side at the top and we all thanked out lucky stars that we were not out shopping that day.

Really we should have seen it coming though - the M6.3 that did so much damage to the centre of the city and the outer eastern suburbs. But we did not. The warning was not that clear...

Nor did some 180 plus soles who paid for it with their lives, mostly inside the main part of the city.

Now that is still mostly closed - they have some of the tallest buildings to pull down, and expect to take as long as a year to tear the Grand Chancellor Hotel down. (amost like starting with an angle grinder at the top of the 26 story building...) And other buildings, too.

It is going to be a long year, I can tell you.

And one of the experts say we could get the aftershocks for another 5 years... Bloody Hell, to say the least.

PeTeR in EaRtHqAaKe CiTy, EaStErN sUbUrB resident...Sleep Tight!

was that another cement truck in the middle of the night...?

Ian Stehbens on May 30, 2011

It is getting late at your place, Peter - hope it is the coffee that is keeping you awake and not the quakes!!

Thanks for a great comment on it all from your first hand experience. And my heart goes out to you all in the eastern suburbs. It is all a bit overwhelming for the city as a whole, but for the CBD and the eastern suburbs it is very difficult.

Greetings from BNE to CHCH!

Peterbnz on May 31, 2011

No, Ian, only one real coffee, plus a decaf about afternoon tea time. I often work late at night, and then sleep quite well _[but shakes so wake me sometimes...]

Check out the press.co.nz, and read the Christchurch story, the Most popular and Your Christchurch sections. The is a lot worth checking out - most of it is found in the printed newspaper that I get most days.

But the Risk of big quake... has many razzeled. We have had some 6700 shakes of some size since Sept last year. While it may be driving some to the fags, I keep clear of stuff like that, Ian.

Have a good day, Mate!!

beegood on May 31, 2011

... one month later Ian: yes, it is special indeed ~~~~~

Peterbnz on December 18, 2011

Another late night for me Ian, but we are now up to 7695 shakes on the http://www.canterburyquakelive.co.nz/ counter!!

The last one was only 10 and a bit hours ago, only a 3.5 that may be noticed by a large number of people or only a few. Depends on the structure of the underlying ground, depth etc...

I did not notice that one, as I were traveling into the city at that time, and it was about 10km away from my place.

But I oftne hear noises in the nite - the ground 'burping' or a noise like a rollar door getting draged on its rollard etc. Usually shows up on the siesmograph at McQueens Valley.

Sometimes, I'm editing photographs on my computer until late at night, and then start looking at comments like those on this site, and the night gets later and later.... its now 1:57am... (almost time for sleep? you say) but I'm nearly finished.......:-)

Cheers, Peter

The world we live on is made of jelly, Peter. Here in Brisbane, after last year's floods and another wet summer coming, we wait to see what the weather will do next. If we are able to go to our daughter's home for Christmas, there is no guarantee that we will get back again when we plan.

The area in the inland SW is already experiencing significnat flooding. If it becomes more generalised as the summer develops there will be a lot of anxiety around.

Ian

beegood on December 19, 2011

But last year's floods were exceptional, weren't they???

Ian Stehbens on December 19, 2011

Dear Maja,

They were indeed, but there is no reason why they could not recur, especially as the weather systems are similar to last year's. The Maranoa and Balonne Rivers are in moderate flood again, right now... and that's where we are heading for Christmas ... to our daughter's home in St George.

Blessings,

Ian
