Geology Reason for the Earthquake Deformation in Tibet as a result of the convergence between the Indian and the Eurasian Plates. The earthquake ruptured a reverse fault along the Longmen Shan Fold and Thrust Belt (LST).
Definition Liquefaction is a phenomenon wherein a mass of soil loses a large percentage of its shear resistance, where subjected to monotonic, cyclic, or shock loading, and flows in a manner resembling a liquid until the shear stresses acting on the mass are as low as the reduced shear resistance. Soil Liquefaction
Causes Flow liquefaction the undrained flow of a saturated, contractive soil when the static shear stress exceeds the residual strength of the soil. Cyclic softening cyclic shear due to pore pressure build-up in soils that would tend to dilate in undrained, monotonic shear. Soil Liquefaction
Common place Shallow, loose, saturated deposits of cohesionless soils Low-lying areas near bodies of water such as rivers, lakes, bays, and oceans. Soil Liquefaction
