In
this video you'll witness the ground opening and
closing during the magnitude 9.0 earthquake
that struck Northeastern Japan on March 11,
2011, with some areas squirting water to the surface.
This is known as liquefaction. When saturated soil
experiences tremendous stress, the water
pressure increases dramatically. This causes the soil to move more freely, behaving more like a liquid than a solid.
