Why Do Buildings Seem to Sink in Japan?

Do you know how some buildings are demolished in Japan?

Instead of blowing them up, engineers sometimes use an “invisible demolition” method that produces far less dust and noise.

Because Japan has limited land and densely packed cities, traditional demolition isn’t always practical.

So they build a large soundproof enclosure around the upper floors of the building.

Inside that enclosure, workers dismantle the structure one floor at a time.

After each floor is removed, powerful hydraulic jacks slowly lower the entire enclosure to the next level.

From the outside, it looks as if the building is slowly sinking into the ground.

The process is quieter, helps contain dust, and allows demolition to continue with less disruption to the surrounding city.

What looks like a building disappearing into the earth… is actually one of the world’s smartest demolition techniques.

  1. They should have done that for the twin towers in New York instead of what they did… But nobody would have made any money from the insurance so…
