Liquefaction

We did some liquefaction experiments to show what happens to the water and the sand when there is an earthquake.  During a quake the squeezing done by sesmic waves happens very quickly and the water does not have time to flow out of the way of the sand particles.  As the particles try to move closer together they push on the water which pusches the sand up.



I think it was really good because it showed what some of the people had been getting around the town. by Keely.
