For those who are wondering of the actual effects that this causes in a earthquake. Water and Sand get forced up. After the last big quake in christchurch the water was upto my knees in about 2minutes. Thick sand/water mix covered everything. Pipes below the ground were often forced up and out, and houses sunk into the ground. Sinkholes, uneven ground, damages roads and footpaths. Its a pretty nasty effect.... and thats without the quakes force alone.

I keep a creepy feeling from this guy, likes hes a mormon or something.
