Soil liquefaction due to earthquake. UTHM GEOFEST'14

- Liquefaction is a phenomenon where saturated sand and silt take on the characteristics of a liquid during the intense shaking of an earthquake. It take place when a quake has increased water pressure in saturated soil and made particles in the soil lose contact with each other, making the soil particularly sand soil - act like liquid. The effect has been likened to slapping a wet , hard beach and the sand beneath you palm becomes jelly.

Great sharing. This happened in Petobo village, Palu, Indonesia 4 days ago. Thousands people swallowed by the earth.
A whole village disappear
@dongjunior25 depends on where you live,..
Perhaps the media there doesn't see it news worthy..
@dongjunior25 i wasn't asking a question tho..
maybe build roads
@@CutieRingoJoy what a silly understanding you have.
What Did you use for your "soil" layers? I'd love to reproduce this demo in my classroom. (I tried it with sand and with store bought top soil but it didn't work so well).
cohesionless soil should be used.. like sand or sandy soil
Thanks
i want to know what is superstructure. does anyone know?
example: big building
Palu earthquake brought me here. Its scary.. So it is very important to do soil assesment before building something
So far, only tall building constructions that conduct further soil assessment, I don't know about housing projects, wether or not they conduct soil assessments
Donggala/Palu earthquake brought me here..
Yes me too
Sama eh
me too
Me tree
me four
Soil lequefaction happened on my graham cake after I put too much cream and milk at the bottom
Thanks for simple and understandable presentation. This is happening in Palu, Sulawesi, Indonesia right now!
I don't know man, your timing seems a bit off
@@fitrianhidayat sorry if i offended anyone. Just found out about this phenomenon and found it educational.
@@thomuso nah man, it's okay. I'm just a bit sensitive about that topic right now, not your fault.
@@fitrianhidayat Lots of people thinking about Indonesia and the people there. Many people praying and wishing all the best for you all
@@thomuso thanks man..
Gempa palu dan donggala membawa ku kesini.... #pray for palu n donggala
simple physics, yet its very dissastrous on island scale
dear sir, can I use the link of your video to demonstrate the Soil Liquefaction. I will acknowledge your name and video link in my personal training video. thanks.
yes my pleasure sir
@@theYenTaro Many thanks for kind gesture ....
cleared the concept the best way! thnx ;)
So damn amazing! Finally I understood how it works, thanks for making this video
So God shakes earth for an earthquake
Clearly explained! First time duh dengar psl liquefaction
Its happened in Palu earthquake 29 sept 2018..
This is the type of Cyclic Liquefaction, not Flow Liquefaction!
Right?
Hello from Detroit! Where did you obtain that container? I would like to get one for my lab... Thanks!
Hello Jesse.. Actually im using mini plastic aquarium in this video. so i guess you can find at any near pet shop..Thanks
I can supply for ur lab
this is the best clear for the concept
thank you 👌👍
I watched japan earthquake video and people there in comment section talking about liquefaction and I've no idea about it so I come here. Thanks for the video.
that is absolutely cool yet terrifying
my teacher reccomends this
liquefaction in palu
hello adib, iam also doin a project about soil liquefaction too, METHODOLOGY!!! and i was just hopin to know the size of the tank u got is by diameter.
+joseph the tank diameter is 30cm. Btw all the best for your project dude(y)
hnx bro
Sensei, I was there in 2001 in shinjuku, there was earthquake but the earth did not liquefied yet.
How come you couldn't just dump all the soil in the at once- why did you have to put in a little at a time?
Dear Adib Azahari, can we use your video (acknowledging your name and video link) in our interdisciplinary project exhibition which has earthquake and Risk Themes? It is a non-profit activity.
sure Emine Oner. our pleasure also to know if this can give small contribution in your project exhibition. good luck then
Anyone here from GRMS
thank, very clear explanation
Mungkin seperti ini yg terjadi di palu ya..
why is he doing that stupid gesture with his hand?
so bad yet so good
Y does this only happen in Japan? Y doesn't it occur in all areas with seismic activity? Or is it actually occurring in other areas with seismic activity?
This can happen to any primarily sandy soil that is below the water table under any seismic activity. It is not exclusive to Japan, though you may hear about it more happening in Japan due to Japan being very earthquake prone. This happens in New Zealand quite often as well.

Sulawesi earthquake 28 sept 2018
Why I won’t live in Big Sky MT
So its quicksand basically
very cool and simpe explanation
Nice video😙✌👍
Worst magic trick ever.
It was a paid actor I just know it
Cool video!!! Very comprehensive and easy to understand!
so cool
Nice
Looks like quicksand
Terbaik brader!
useful experiment for my students
Thankyou ❤
whos from school?
Pray for Palu Donggala and Sigi
Indian man on yt does it again folks. Played this vid in Earth Science, thanks!
Soil liquefaction is quicksand's older brother
grate
But what made the buildings move in palu?
Earthquake
Cool
Siapa yg dari indonesia
Saya dari Russia.
1000' th like
So the water table gets thrown up
Nyc
Oh begitu..
so meaning no super structure or well designed structure/building can escape from this kind of phenomenon sir?..
is there such study or whatsoever test to be able to know area or soil is liquefaction prone sir?.. Thanks a lot for your response!..
patty me there is a lot of info! I am from Los Angeles and we have this information for our city: geohub.lacity.org/datasets/8b5ae7c5bc794e1bb97fc213ab1c6268_5
I don’t get it
generally, is more like density concept.as we know, water is very light density then soil and superstructure/building as shown on this video. thus while liquefaction occur, which thing is very high density then water will deserved go downward.
Thanks for upload
Very good way of explaining...Ty so much
This is the best illustration i have ever seen. Thank you so so much. This is the best i repeat.
WOW :D
Simple experiment. Can be done in the classroom at school.
Appreciate for your video explanation.
Great video
legit question, how to encounter it?
Thank you many awesome :)

This is awesome. Had no idea it worked like that. Came here out of pure curiosity. Before it made no sense, but now it does! Bravo!
Thankyou
Perfect demo sir..Hats off
Amazing
Smart wat of demonstrating it
天啊，陷進去耶。
Sort of a misnomer. The soil does not liquefy but rather water simply moves. At least that is how I look at it. If no water below soil then no liquefaction could happen so rather water displaces into soil. Would be more accurate to say "Water solidification."
