This is a great video describing the impacts of liquefaction on buildings, parks, sewer lines, etc. Getting videos like this, where experts can describe the damage and WHY it happened is so important in getting the public to understand how earthquakes can affect where we live. Great job, keep up the good work GEER.
@choppyusmc This can happen anywhere you find loose saturated sandy soils, like article fills and natural river deposits. We generally think of sands when we think of liquefaction, but gravels and silts can liquefy as well.
Good video. Have you tried searching for videos on UA-cam of the liquefaction in Christchurch, New Zealand? Christchurch is New Zealand's second city, and between September 2010 to the present, a series of earthquakes have induced liquefaction on four different occasions - 04 September 2010, 22 February 2011, 13 June 2011 and 23 December 2011. Around 9000 homes have been abandoned because of earthquake damage, and most of this is because of severe liquefaction damaging sewerage, power, water.
Great video - thanks for sharing. There are literally dozens of Liquefaction videos being shared from Japan at the moment... Together with the continual earthquakes and the seabed/shelf off Japans coast it makes me wonder what is yet to come...
@TheNephewHelix Liquefaction is not limited to coastal areas, but you often find loose saturated soils in coastal areas. Inland river valleys and deltas are also susceptible, as is anywhere you find loose saturated sandy soil.
There are also many liquefaction amateur videos from the Christchurch, New Zealand earthquakes of 2010 and 2011. There, liquefaction occurred in suburban neighborhoods, where people shot videos of this grey sandy muck bubbling up through their lawns and driveways.
Do you have anyinformation on what happens to gas station fuel tanks? I am in the process in intervening in the design stage of a gas station which is located 31m from an estuary with proposed tanks which would be located below or at sea level depending on the height of the tides. I want the tanks on the surface. If anyone has information on damaged fuel tanks intalled in estuarine environs damaged by earthquakes could you please contact me?
Get some cornflour & add water. Shake it & poke it - it's the same as liquefaction. The water pulls on minute grains causing an adhesion bond. Water spiders sit on the water surface using surface tension.
@@sixthsenseamelia4695 i googled cornstarch & water and the term that came up was "dilatant" or "shear-thickening" (reading about it was great btw so thanks for bringing it to my attention). But dilatant materials lose viscosity when the shearing force is removed, whereas in the video there are footprints on the mud that remain intact with no foot on them.
There is a term in ceramics for this movement in sand, when you stand still with your feet in the sand next to the ocean. With each wave your feet sink a little.
@@kevinmathewson4272 sure. It’s thicsitrophic. That is phonetic, I’m not sure of the exact spelling. I was throwing some bowls and had to put some on top of an old frig. The vibration of the motor caused the bowls to collapse.
@@gingercox6468 damn, that's fascinating. also i managed to find the word from your phonetic spelling, and it's thixotropic. there's a bunch of cool stuff to read about it, thanks for pointing me in this direction!
@workingclasssociety You really can't fathom why people who live next to a major subduction zone would go to a place that has just been rocked by a major subduction zone earthquake? Well in that case. 'Here's your sign"
@CapeKell It was a 9.1. And If the buildings are made to withstand actual eartquakes, like in Japan, the damages can be small. Infact, the most part of the destruction was brought by the tsunami. Sure as hell that a 9.1 Richter in the US, where no one wants to spend a cent in safety, would have erased to the ground every single building. San Francisco, ring a bell?
the sheered pipes at the water treatment plant are also what happened under the reactor facilities at Fukushima

Facts. I’ve learned SOOO MUCH about how our earth works by watching videos such as these.

how is this sand from liquefaction different from the sand around the sand blows?
@turbotrana It was mostly reclaimed land near Tokyo Bay, then more natural deposits as we moved north.
was this reclaimed land made from fill, or original ground?
Was this mostly natural ground or reclaimed ground. Is it just certain areas that get subject to liquifaction or is it widespead.

Where to start?I live 25 miles as the crow flies from MT st Helen and I thought I seen destruction at its worst but Japan got it way worse!

2:25 what a tragedy
Liquefaction can be found on any sandy beach after or before the tides turn.
Yap, something like that. ..but this wave wos mutch biger !
Or after a wave recedes.
Nope. Not the same.
I wonder how much human history is lost getting sucked into the Earth.
Mud flood

2:59 the mud almost seems membranous. How is it able to ripple like that without this person's feet sinking in?

Great vidoe. Thanks for sharing!!
Realy crazy .good video !

do you know what that term is? I'd love to read up about it.

Sounds like Scott Disick. It’s just uncanny
thanks
muy triste.
Billions in damage
4:50 "containerized...uh, cargo containers..."
Huh?

Does everyone from Oregon state sound like Mike Parker, or is it just me???!?!??? 🤣😂
As an OSU person myself, you're absolutely right 😂 we have that passionate nerd dialect.

WHERE IS THE 9.0 EARTH QUAKE DAMAGE? LOT OS LIQUEFACTION BUT NO 9.0 DAMAGE!
Why is the Oregon tax payer footing the bill for your research in Japan?
true 9.0 damage would have NO structures standing. 6.0 maaayyybbeee
This video is from an area more then 100 miles or 160 kms from the earthquake epicenter.
