Lateral spread
(a) Lateral movements in a fractured mass of rock or soil, which result from liquefaction or plastic flow of subjacent materials. (b) Lateral movement of intact blocks of soil or rock material which slide on a gently inclined planar surface, such as a bedding plane or a liquefied sand layer. (Neuendorf, K.K.E. and others, 2005)
