Abstract: When the tone or feature on the Landsat Imagery appears abnormally andextends along a straight line,it is called lineament.The lineament largely represents the traces of deformation of earth crust.Interpretation of the lineament on the Landsat Imagery shows the followingfeatures:1.We can understand more thoroughly about the known rifts;2.A lot of rifts that may be neglected as detected with common methodscan be replenished;3.In the area covered by quartermary sediments,we can discover thedeep-situated rifts by using the method of perspective message;4.We can find the rock undergoing plastic deformation stage or the stressconcentration belt in stress concentrating stage;5.The belt with-lineaments more concentrated or the interface betweendifferent geological bodies in large area indicates the existence of great rift beltswhich pass through the earth crust.The most of strong earthquakes often occur in the great rift belts.Theirconcrete locations are generally at the points where the active structure or thestress concentration belt intersects the old rifts.In regard to the occurence ofstrong earthquakes,the stress concentration belt with its stresses concentrating ismore dangerous than the active structure.
