Sand liquefaction

Hopefully this will help explain what Liquefaction is, and how it occurred during the earthquakes in Christchurch , New Zealand. Digging out the sand that was brought to the surface and deposited via Liquefaction and wheel-barrowing it out to the roadside. Watch how the sand, under vibration, turns into a liquid state. This is what happened in the earthquakes of Sept 4th and Feb 22nd in Christchurch New Zealand and results in instability under buildings and causes them to move or, ultimately, collapse.
