EARTHQUAKE FAULT RUPTURE PROPAGATION THROUGH SOIL

WebThe earthquake shakes the ground which disturbs the compact soil structure. The sudden load application (or shaking) builds up the excessive pore-water pressure that detaches the soil particles from each other. The soil loses its strength at this instance, and the soil firmness reduces to zero. It behaves like a liquid. WebBuildings can even sink into the ground if soil liquefaction occurs. Liquefaction is the destabilization of sand or soil when groundwater (water underground) is forced out from between grains during the shaking of a moderate or strong earthquake. If liquefaction occurs under a building, it may start to lean, tip over, or sink several feet. churchwarden smooth fishtailWebLiquefaction susceptibility maps outline areas where water-saturated sandy soil loses strength during earthquake shaking.
