what is likely to happen to unconsolidated, wet sediments during an earthquake?
Liquefaction-Liquefaction is a processes that occurs in water-saturated unconsolidated sediment due to shaking. In areas underlain by such material, the ground shaking causes the grains to loose grain to grain contact, and thus the material tends to flow.
Ground Shaking-Shaking of the ground caused by the passage of seismic waves near the epicenter of the earthquake is responsible for the collapse of most structures. The intensity of ground shaking depends on distance from the epicenter and on the type of bedrock underlying the area.
