Christchurch earthquake: Watch how liquefaction occurs

[pyrofella]

Good example.....amazing...Thank You

[izaiah1234567]

but how does the word shake hu? hu?

[jshawnk78]

You know I don't think I've ever hear off that happening in California EQ's. Is there something I'm missing.

[maddersmudder]

@jshawnk78 It most definitely DOES happen in California Earthquakes. The damage to the Marina district in San Francisco during the Loma Prieta quake in '89 was due to liquefaction.

see how easy it is for God the father to clean up his earth? liquefaction would take care of all of the ceament man made and lava would take care of the rest.

[stormcats2]

i get it, thankyou for posting

[mohanferrer]

kinda like non newtonian fluid really aint it?

[projectcablex]

clever.

[callmeshane303]

Far out.

Demonstrates the principle quite well.... "and this is why the buildings are falling over".

[fjbutch]

Well, there it is right there,,,great demo...good clip..

[yloveyl]

the place which occur liquefaction will sink soon. very soon so prepare to move

[VolkgartenBySquirrel]

Bill Nye is back! Thanks for that very educational demo

[robloxcoconut219]

the dirt got carsick and melted.

[TheAngryarchangel]

so if you take dirt and water and you shake it up it makes mud? holy shit! genius. how about explaining how the earth in japan can sway as if it is floating on water. because its floating on water! what happens to soil that is fully saturated? IT SINKS!

[zoeyp]

am i high? i'm reading all the other comments and everyone's raving about this video, but i don't get it at all. whatever, dude.

[fionamarie2008]

This is fantastic!!! perfect demo for a science class thanks 

[anavywife28]

does it re-solidify? I hope it does because Japan is going through so much right now.  I am hoping it will solidify again, maybe they can sprinkle some cement in those cracks

[jenzmif]

Wow, that is a great demonstration, thanks!

[Cav3man93]

0:17 to 1:20

see the difference. wow.

[BuzzardlyThings]

Perhaps I'm glad I only have to worry about hurricanes.

[MegaNorthMemphis]

No words..just wow! 

[Nipplemuff]

Very nice demonstration

[nzecureuil2]

awesome demo!

[Onekatmandu]

Thank you! :)

[crazy948]

thanks for this demonstration. i live in a city said to be prone to liquefaction. now i know what to observe in case earthquake happens.

[KiteChaser]

wow, I used to do that in kindergarten in the sandbox!

[SepherStar]

Excellent example of liquefaction.

[posteador]

Brilliant demo, thanks!

[wiqi22]

Brilliant Brilliant Science demo vid..

[feedmepaper]

Excellent demonstration. Thanks so much for this. :)

[CapitanoGUC]

@feedmepaper did he die ???? :-O

[littlegreywitch]

I thought it was when the earth caused larger clods of dirt etc to crumble allowing trapped water to saturate it and rise to the surface as silt. (the stuff in the wheelbarrow). The clods normally act like drainage under the top soil however once they disintergrate they crumble into the water which mixes with it as it rises through the now exposed topsoil

[sallyt17]

I am very pleased to be the first to say thank you for a very practical and enlightening demonstration. The perfect science lesson.
