Christchurch Earthquake Showing the sand liquefaction process with vibration

Thank you to the 575,000+ people who have viewed this clip. It was only intended to show to a few friends what we were living upon and what came out of the ground in our recent series of earthquakes. Never in my life did I imagine it would go viral and get so much attention.. Thanks Again.

.Hopefully this will help explain what Liquefaction is, and how it occurred during the earthquakes in Christchurch , New Zealand. Digging out the sand that was brought to the surface and deposited via Liquefaction and wheel-barrowing it out to the roadside. Watch how the saturated sand, under vibration, takes on the characteristics of a liquid ( it doesn't change to a liquid, but behaves like one) and then returns to a solid state once the movement ends. This is what happened in the earthquakes of Sept 4th and Feb 22nd in Christchurch New Zealand and results in instability under buildings and causes them to move or, ultimately, collapse.

Good explanation though not only your ancestors wiped out the local indigenous from this lands but they also build your cities on quick sand...ayaha!

[ArgentumNZ]

@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 :-)

We are contemplating asking for our money back as the land is 'faulty'. *drum and cymbals*

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

we saw you on the news. nice work!!!

[ArgentumNZ]

@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.

Thanks to ALL of you.

Thanks for this video, very educational. My best wishes go to those in NZ who have been affected by the recent big earthquake.

[ArgentumNZ]

@peshwengi Thank you for watching and your wishes to us all here. It's going to be a long recovery.

Excellent science demo!

[bebu2222]

Thanks for giving such a clear demonstration. I'd never heard of this before. I'm really sorry that you must deal with this... and again possibly, after today's quake.

[Banez1991]

That's incredible.

[NewGenesisband]

WOW!!
