This is a video of soil liquefaction during the earthquake on March 11, 2011. I live in Koriyama, which is a little over 100 miles from the epicenter of the earthquake. Chiba is about twice the distance, or further than Koriyama.

You can hear her whispering “Yabai” which is basically the equivalent to “OMG!!!” In short, what’s happening is that the soil under the ground has been turned to quicksand. The pressure from the earthquake is forcing the water into the streets. There are some other videos if you search that show some of the other things that happened in Chiba.

Despite this being a very old video, this is the first time I’ve seen it.

Just thought this is interesting.
