Liquefaction

This video we made will help demonstrate the concept of liquefaction. Sand (loose sediment) was used and water added to create a saturated soil as in nature. During an Earthquake, seismic activity (shaking) causes sand to compact and water to rise up between the grains creating a liquefied state that cannot support structures.

What is the smallest earthquake you know about that has caused liquefaction?

@TomasYoda with this most recent earthquake in japan ive seen firehydrants that are only exposed at the tip, buildings that have turned to a massive and unsafe tilt (likely in need of rebuilding, or possible use as a memorial) so i suppose, if the magnitude is large enough, a house could be sunk down to its roof, in theory.

@qwerty812 yes but not very deep.

Empty swimming pools, underground pipes complete with their manhole covers and tanks at gas station float up out of the ground.

@theeianie Just use soil - sandy soil works best - and get it good and wet but not puddling wet, then shake.

There is a great demo in a wheelbarrow here on youtube - wheeling the barrow along makes very effective shaking.

i like the project u did.im making a project of the same thing

Have not seen entire houses sunken. Have seen a huge piece of road in Christchurch missing and cars crashed in the hole. Cars are not able to drive through the silt that has come up and covered roads.

in cases of liquefaction, would the entire house sink?

I wanna do thise with a gingerbread house and hot chocolate as the soil. Yum

[nenitosoyyo]

really good example of what liquefaction in earthquakes can do.

please tell me how this was made ..it's really important like as as possible please pretty please tell me id really appreciate it!
