Pressure at given depth below ground

If one plans to build a survival structure below ground then certain pressure can be expected when
liquefaction takes place during the near continuous shaking at the time of a pole shift.

Different kinds of sand have different densities; however 2.3 g/ml is a typical value. Water has a
density of 1 g/ml. The following chart can be used to predict the amount of pressure on a container
or survival quarters at a given depth below the surface of the ground.
