@seyoumeye Well, to be truthful we didn't wipe them out.... they were better than Her Majesty's troops so we entered into a 'treaty' with them to purchase/steal the land (delete as applicable depending upon your point of view) . That's a whole other story which we are still arguing about :-)

No offenses, but have you heard of certain "Dragon Currents"?
Sadly cathedrals builders (highly addicted to gold) and their cities are built on a so called "sacred sites" by the local indigenous people. These are not meant to be places of dwelling but an ideal place to hold a "sacrifice ceremony".
Glad you are safe, but I assure more tremors will sunck many coastal cities.
Blimey...that was very interesting. It's great to understand how it works now, it was a mystery to us. Good job and all the best for you and your city. We're thinking of you all.
The two recent NZ earthquakes have certainly produced a lot of liquefaction.
Since many/most of the earthquake videos we see on YouTube have come from California and Mexico, where it's far more dry, liquefaction looks bizarre as we rarely see it. Actually, it looks bizarre regardless. The vehicles trapped in thick grey sludge, sometimes almost immersed, are a kooky and unsettling sight.
Firstly can I thank all of you who have viewed this video and offered messages of support to the people of Christchurch and Canterbury. Thanks must also go to several media outlets that picked up the video and gave it national and, hopefully soon, international coverage. It was designed to be just a little informative video for some friends but has gone much wider than that. Regards ArgentumNZ
This is thixotropic in action, exactly the same as you can do with cornflour or avalanches. The molecules are (roughly) rectangular but stacked up at all angles until vibration occurs then they all shake down the same way and slide off one another.
Thank you for showing this video, i'm in canterbury and it's great to see what happens, i was totally fascinated by it, even if saddeed at the same time
@abnunga That's very funny... but it does seem quite accurate too. The lot I was shifting was from down the back of the garden... I have a theory that revolves around getting the water into the ground sufficiently to saturate it. I think I'm going to suggest that it's run-off from the garages. Lets face it, they are down the back of the section by the lovely sunken garden/rose bed and the law of Murphy says if it can it will.... :-)
@alone4u2be Thanks, my 2 minutes of stardom. I thought they wanted just a quick recorded interview but we ended up doing a live section.... and it's all thanks to the 60,000 people that thought watching a wheelbarrow of sand behave differently was as interesting as I did.
For those who don't seem to understand the term "liquefaction"
liquefaction (lkw-fkshn)
The process by which sediment that is very wet starts to behave like a liquid. Liquefaction occurs because of the increased pore pressure and reduced effective stress between solid particles generated by the presence of liquid. It is often caused by severe shaking, especially that associated with earthquakes
It is not about the sediment becoming a liquid OK?
I think it's quite sad that a simple vid of a guy trying to bring a bit of education to the world out of his misfortune brings out the conspiracy theorists, the racists and skeptics ("it's photoshopped" ). I really think that Youtube should turn comments off full-time since the 10% of wackos spoil it for everyone else.
@ArgentumNZ thanks for an informative vid and hope you get over your disaster soon.
British people just want attention on the earthquake and their not even KIWIS,INFACT they ruin everything to do with new zealand with their annoying attitude and accents..they make nz look miserable,cold ,gloomy and depressing just like their own country Britian is
ignore jd55000 everyone, he ruins NZ with his annoying attitude and bigotry. he makes NZ look like a miserable, gloomy, depressing, and moronic country which I assure you it is - for the most part - not.
Thank you! I just showed this to my almost 7 yr old, and he now has a better understanding of what happens in a quake. Kind of hard to explain to kids without some sort of visual aspect.
Thank you. That's why I put it there (in educational) so people might get a grasp of the process. It's easy to understand when you see it happening but for people outside CHCH it's hard to describe or comprehend..
Has this hit the TV screens yet? Excellent depiction of liquefaction before your very eyes, albeit in wheelbarrow. Superb if just a little frightening
@wmsilvia That separation is exactly what Liquefaction is that I'm demonstrating. But when I stop did you notice it returns to the 'solid' state and I can empty the barrow in 1 piece - the water doesn't remain on top.. I'm not saying it's liquifying (the sand turning to liquid). Perhaps I'll change the title (if I can) to say Liquefaction since it's obviously causing confusion (3 similar comments out of 35,000 views). Thank you for your comment.
@wmsilvia Although it's called LIQUIfaction, you're right, it is not a liquid. But is does have FLUID properties. Gasses, liquids, and solids can all have fluid properties. For example flowing air in gas or a debris flow of solids. Water saturated sand that gets shaken will have fluid properties until the shaking stops as the video shows.
Great video. I'll be showing it in my class tomorrow.

@JD55000 you're outlandishness disgusts me! Thanks soo much for this video mate, for explaining what liquefaction is and what its like, LOVE FROM A FELLOW KIWI xx
Thanks for the vid mate, it's so hard to explain this effect to people who have never driven a wheelbarrow full of the stuff! Lets hope we all finish removing it soon. Make sure you get a breathing filter - St Johns have been handing them out, and I think they are supposed to be handing them out at the water collection points as well.
Very good demonstration. This is one of the main problems with the new madrid fault line as well. Arkansas has had over 800 earthquakes in the last six months. I send my prayers and well wishes out to New Zealand.
@hoosierhiver Yep, on average, the problem is that in the last two weeks they have had over 100. I print out the quakes from the USGS, when I go back later and print a current read out, some quakes have either been removed completely or the strength lowered. Something isn't right. Now FEMA is having a drill this May for the New Madrid threat.
@midsta Ahh I think that was the first point at which creative real estate marketing raised it's head. Imagine if you will a land of milk and honey only 12,000 miles away in the sunny south pacific. Only 6 months journey by boat (if you got there). The boats arrived in Lyttelton (a sunken volcanic crater no less) and the new residents had to walk up and over the rim of the Port Hills (where these current quakes are predominantly originating) and saw their land.......a swamp.
Wow, imagine that time 100... very sad watchingthe devastation for the last week, wish I could help. Have made a donation and keep hoping for the best, will be reflecting during 2 minute silence tomorrow. Love you Christchurch x
hahaha... I've been in NZ for something like 38 years now... but the voice sets once one gets past about 14 yrs of age. The accent is softer... believe me. Thanks for your comment though. it added some humour to the day.
@L33Tspartan No it hasn't been shopped. Pity you don't know what you are talking about - an armchair expert no doubt. Come over and grab a shovel and help out.
@ArgentumNZ haha i was just joking as were most everyone else that says its shopped sorry man. I will see i i can donate some money torward the relief effort
@L33Tspartan . Sorry also for my snapped response. I was tired and irritable and the blasted sand is so fine when it dries out it's like cement, or talc, and my eyes are itching.
I wish it were shopped.. in fact I wish it hadn't happened ... But it did and it's real. I kept the whole raw video to do it in one take rather than making a pretty version (if I had the tools).
It's not changing from a liquid to a solid or the other way around. The vibrations are pushing the water out of the sand. The water goes above the sand and the sand sinks down. They're just separating.
@HighwarlordJC, I guess you are technically correct in that the sand itself doesn't turn to liquid - but that is to liquify. *(that's Physics).
This process we call Liquefaction is a geological term which refers to the process by which saturated, unconsolidated sediments are transformed into a substance that acts like a liquid. *thanks Wikipedia*
@saintpine : Christchurch is basically built upon reclaimed/drained swampland. In areas where they know the soil is 'loose' or on top of peat we are sometimes made to put piles down and concrete them into the base foundation to provide stability. ... but this is a more modern technique.
Wet sand, gravity says heavy stuff falls. The sand falls to the bottom, and the liquid floats on top. Don't see any sand liquifying here, but it certainly is interesting; I'm not saying sand doesn't liquify just that this video doesn't show it.
You are right, it's just the popular term used for this phenomena of fine sand saturated with water, sand liquefies at very high temperatures and solidifies when cooled.
NZ was attacked by a silent Tesla weapon called "Scalar Weapons" and if you Google it and check it on Youtube you will see hundreds of informative links. This is related to all the whales beaching themselves 6 months ago in NZ.
