Solifluction in Urban Japan after the 2011 Earthquake  

A plaza built on reclaimed sea sediments settles after the earthquake.

Here's an amateur video of the results of settling sediments beneath a plaza in Japan. The earthquake jarred the saturated soil beneath the plaza, which led to the cracks and water and mud rising to the surface. Two things strike me:

  1. The rapidity with which the water seeps above the pavement.
  2. The absolute calm of the people in the area. If the earth opened up and urped muck in NYC, nothing less than pandemonium would ensue.

It amazes me how cultural differences can affect not only the behavior of the individual, but also crowd rection in sudden and potential dangerous circumstances.
