Thank you to the 575,000+ people who have viewed this clip. It was only intended to show to a few friends what we were living upon and what came out of the ground in our recent series of earthquakes. Never in my life did I imagine it would go viral and get so much attention.. Thanks Again.

.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 saturated sand, under vibration, takes on the characteristics of a liquid ( it doesn't change to a liquid, but behaves like one) and then returns to a solid state once the movement ends. 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.
