- This is my back yard after a 6.3 earthquake hit Christchurch on Monday 13 June 2011. The liquefaction started gushing up about 5 mins after the quake and was very noisy. The 6.3 quake that triggered this was just an aftershock following our deadly Feb 22 quake (6.3) and the biggie on Sept 4 2010 (7.1).
Our house had already sunk in a previous quake, so I was concerned when this started as it was downhill into the house from the geyser source.
Unfortunately I freaked out before it got really bad and stopped recording so I could close doors and dam them with towels. Some water did end up inside but actually seeped through the cracked foundation caused by the Sept 4th quake.
See my next video upload "Liquefaction sinkhole" to see what it looked like after it had finished.
Thanks for sharing. This is the BEST video I have seen to show how bad liquefaction can be around someone's house. My heart really goes out to those living in liquefaction areas. Its bad enough getting slammed around here in Lyttelton without having the added problems you guys are experiencing. Wishing you all the best.
This excellent video could be shown in a university geology course. Sand boils are one of the signature features of large earthquakes, but due to their ephemeral nature, and people having other things to do in the moments following a strong earthquake, they tend to be mistaken for a broken water pipes and get ignored. They are one of natures rarest displays.
yeah this is the only footage i could find of a boil being formed after the christchurch quake
That's the classic sand boil structure that ends up looking like a small volcano as the silt builds up around the spot where it's erupting out of the ground. Up till the 2011 earthquakes in NZ and Japan, there were almost no movies of this actually occurring, only photos of the result after the water had stopped flowing. Now there are multiple videos of the real thing as it's happening, like this one.
The more recent commentators on this need to know that the videos of liquefaction breaking out in Christchurch and Japan happened in the immediate aftermath of damaging earthquakes where quite simply there were bigger problems for the emergency services to deal with. Not only that, this was being repeated across thousands of properties in eastern Christchurch.
So, easy to be an arm chair commentator here. I am not. I was in Christchurch for all of the quakes and saw the damage and participated in the Student Volunteer Army relief work. There was probably not much she could have immediately done, and many houses were abandoned after this particular event because their owners had been brought to breaking point by this - the third major outbreak of liquefaction in under a year; by insurance hassles with houses that were slowly suffering ever more damage.
Until you experience this first hand and participate in the clean up, it is difficult to understand the nature of liquefaction, how it happens, and the consequences.
Please show the end result when the water stopped flowing. Show the "water volcanoes".
Did you put down a rolled-up towel to block water coming into the house?
You did better than I would have. I would have been out.
Hi, do you think it is possible to get the exact GPS coordinate of the sand boil location? You can access it from Google Earthh. I am working on the research on liquefaction of the sandboil. Getting the coordinate of this one will be useful.
same, no response?
@@l.jboylan6704 Did you try a private message? No one wants to geolocate their home online
Excellent recording, cool woman, and only one, "oh my god". If she'd been American, it would have been non-stop, "Oh my gawd! Oh my gawd! Oh my gawd!" hollered at the top of her lungs. Which is also what she'd say if she were happy.
Hi Minniecat, I'm working on a documentary and would love to include your video. Is there an email I can reach you at?
How did you clean up all the mass
Any video update in 2020?
@Timeup0823 It's definitely liquefaction - sand doesn't come out of the water pipes! A common site in Chch unfortunately... :(
aosangel water that goes through dirt will pick up water though, liquefaction stops after the earthquake stops, so still flowing liquefaction sand wouldn't exist after the tremors.
@@boxwithoutatop7243 "...so still flowing liquefaction sand wouldn't exist after the tremors."
And yet it did, Mister Beckwith.
Hey, I was wondering if I could use this footage for a presentation I am doing at university, it will not be published publically, I was just wondering you would like me to credit you for this video. My condolences about you backyard.
do you have any money?
Yes you may. Sorry for the late response.Backyard ok - house was a total write-off
I hope your sub pump is on…
Nvm! Just read your description. I would've connected pipes together and made it to where it leads to the gutter, or the neighbors yard.
i reconise your yard. i think i helped shovel it
Wow that is cool!!!
Show us the after math. Don't leave us hangin mate?
The end is near
Six years later - hasn't happened yet.
You should've called the city or the fire department to help contain the water, otherwise it could get into your house and neighbour's houses... as I see from the description it already has. I would've called someone the second I noticed something like this.
Yoite You clearly are not aware that this event was not localised, but was occurring all over the city - there had been an earthquake, after all - and the First Responders were already up to their necks in call-outs.
Like MarsFKA mentioned this was the immediate aftermath of a major earthquake. There’s really nothing that emergency services could have done. Mother Nature is in charge and only stops when she’s ready.
Lives being saved far more important than “hey look my backyard is gushing” lol
Looks like a water pipe broke
ffffaaaaaaarrrrkkkkkkkk
Don't just stand there call 311

This is just sooo pathetic. Oo-ooh, shiit, my god ... GRAB SOME FUCKING TOOLS AND SAVE YOUR HOUSE.
This has absolutely nothing to do with liquefaction. Liquefaction occurs when partially saturated soil loses its stiffness and ability to weather shear stresses. I.e., the soil (which needs to be heavily saturated with water for this to occur), starts to behave like a thick jelly-like liquid. It's even in the word liquefaction: lique (pertaining to a liquid), faction (from old Latin "factio" or "facere", which means "to do/make"), in other words: "to make [something] liquid".
This is most likely just a broken pipe, or perhaps a natural well that was pressurized by the earthquake and found a way to the surface. Some people find this hard to believe because of all the sediment coming up with the water, but what do you expect? The water has to travel through God knows how many layers of soil. Of course its going to pick up silt on its way and spew it out once it reaches the surface.
If you had liquefaction in your backyard, your porch would have moved and swayed, you included.
No disrespect, but did you read my original description?
This is liquefaction, caused by the 6.3 magnitude earthquake some minutes beforehand. Liquefaction must necessarily involve sandy/silty soils, liquid (in this case water) and agitation (in this case the massive earthquake that had just hit).
Our backyard and entire suburb experienced liquefaction after three earthquake events in Christchurch, one of which also killed 183 people. Our house was a write-off. Its concrete slab was broken into at least 8 pieces, and some of this liquefaction entered the house via these cracks.
Google "liquefaction" if you don't believe me.
I am not sure where you are getting your information that this is not liquefaction and rather a "natural well" (not too sure what you mean by this), or "broken pipe" (the owner should know if this were a broken storm or sewer drain pipe). As a current researcher of liquefaction effects in Christchurch, I would agree with the video poster on this (thank you for posting this great example of liquefaction and sorry you had to experience this first hand). Something not mentioned in your description of liquefaction is that it requires a build-up of excess pore pressures to explain the loss of stiffness and strength. As these pressures build up and the soil liquefies, it will want to relieve the pressure. The sudden need for pore pressure relief may induce water flows that concentrate towards certain points on the ground surface due to the interlayered soil deposition prevalent in Christchurch. For example, there may be a less permeable soil layer nearer to the surface trapping the excess pressures that were created below. The water will then flow towards natural paths of lowest permeability (e.g. around or through some sort of opening in the less permeable layer). Hundreds of sand boil examples like this occurred all over Christchurch.
01:25 Well, she did say the name of Jesus, but it was in vain. Whosoever shall call on the name of the Lord shall be saved. But God wants us to pray in spirit and in truth. Using Jesus as a swear word will not get any help from God.
No because god doesn't exist
Do you exist? Every person has a spark from God's Spirit within their heart. So if you exist, then so does he. If I believed God didn't exist, then neither should I believe you exist, after all you are less believable than the one that people call on 2,000 years after he walked on earth as a man.
Regardless, we should not invoke the name of the Lord Jesus Christ in vain. If you don't really want Jesus to be your Saviour, then call on another name.
Wow, we've gone from irrational beliefs to outright paranoia. Congrats?
field16 I believe allah does exist but you don’t need to go commenting on the video about it. Let the person do their own thing.
@@minniecat600 clearly God exists and He is angry- look at the video.
