Now stand still, wriggle your toes and feet. If conditions are right, you could sink a little as the sand around your feet becomes sloppy. This is similar to what happens during liquefaction. Over thousands of years, rivers deposit layers of silt and sand in many places, especially in low-lying ground and near the coast. The top layer of sediment can become flat, firm and dry — ideal for building on — but this often hides layers of waterlogged sediment beneath. Severe shaking in an earthquake puts pressure on the silt and water particles in these waterlogged layers, turning once firm sediment into a liquid.
Pressure on the liquefied layer is increased by the ground above it pushing down. Water fountains and sand boils can burst upwards through any cracks. If you push the plunger down too quickly, the water and coffee grounds are put under pressure.
Earthquake motion can turn loosely packed, water-saturated soil to liquid—"liquefaction. The magnitude 6. There, more than 30 buildings were damaged or destroyed, and gas lines were broken, igniting fires.
