Abstract

 The slopes of the edges of the Rajdoon River in the north of Ganaveh have the high potential of SLIPping SLIPpage. The occurrence of strong EARTHquakes increases this potential of instability, severely. The depositions of downstream which were formed from siltstone, has have the ability to produce the circular SLIPs, but the depositions upstream which were formed from the mudstone has the ability to produce the are capable of producing columnar- plane SLIPs. In these cases, the occurrence of an EARTHquake with the horizontal speed (velocity) of more than 0.14 g (DBL) in the area of Rajdoon causes the instability of slopes with the gradient of more than 20 degrees. These SLIPs block the way of water flow and also would lead to the formation of natural dams in the way of stream stream bed. The result of This event and the breaking of dams would result to the in great flood waters and also the destruction of some parts of Ganaveh city.
