Raised beaches has raising gradually since 30-50 thousands years ago, and the amountof raising has estimated 1-3 milimeters per year. These matchless beaches are observablefrom port of Jask to Gwater bay, and continue to after port of Karachi, and therate of raising increase from west to east. So that their height is about 1 meter in Jaskport, more than 100 meters in Chahbahar and Tis, and about 500 meters in Karachi ofPakistan.The Cause of raising beaches is related subduction and tectonic forces in this part ofIran beaches, that the amount of subduction is 5 centimeters per year and intensity ofraising in beach is very more than plain and Makran mountains. Since the subductionis active, the raising of beach is continuing yet, and beaches are uplifting steply.There is very reasons of prove raising beaches that will be point in later discussions.
