Best example of earthquake-induced liquefaction. This video was "accidentally" taken during Niigata earthquake in 1964. The occurence of liquefaction clearly be seen from the video.

  • Oh lord here come the comments. Now everyone is an expert. On youtube. Typing messages on a video.

  • The person who posted the video is correct. When ground liquefaction occurs in wet sandy soils you will often get what are known as "sand gysers". These are really strange phenomena that look (as raff62 observed) like a broken water pipe at first, but when the earth quits shaking they solidify right up rather than running off or washing back into a hole. That's just what we see in the first 18 seconds. Then when the next shock comes along it really gets going. We just don't get to see the end.

  • Liquefaction has nothing to do with water...it can involve it but it doesn't require water. If you shake soil and sand violently it will flow like a liquid until the shaking stops.

  • @mschneider18xx lol your wrong.

  • @echoesroll

    sounds interesting. i will look into it. internet is great!

  • its a river of... dirt?

  • @mschneider18xx Um... Thats not exactly correct. After the 6.3 Christchurch earthquake in February of this year, We had four piles of liquefaction in our garden. They keep bubbling after the quake finished. Actually it took days for them to stop.

  • @mschneider18xx is this what's happening in japan now? there's some videos going around showing the ground as if it is floating - scary stuff

  • 90% of the so-called liquifaction videos on Youtube are mis-identified water-main breaks. This video is the real-deal: the liquifaction is violent, and proceeds in pulses as S-waves compress and uncompress the ground.

    Clue: if the "leak" continues after the quake is over, it's a broken water pipe.

  • Thsi video proves that we are little more than fleas on this earth. One day it'll shake us off without so much as a snort.

  • old world secrets the omega

  • @gramosjr I tinkle on your god.. what what?
