| Abstract | The Mae Ping fault zone trends NW-SE across northwestern Thailand into Myanmar has sinistral strike-slip movement where estimated 500 km long. This fault zone first occurred in late Cretaceous and has been developed until now. Digital Elevation Data and satellite images were used to identify lineaments and fault. Morphotectonic analysis was used in order to better understand uplift, exhumation and erosion of the Mae Ping fault zone. Geomorphic indices were generally used to define tectonic active zone. Mountain front sinuosity index and Valley floor width to height ratio were selected. Most evidences show that the Mae Ping fault zone high tectonic activities until present. The active regions are identify by low values of mountain front sinuosity and valley floor width to height ratio are supported the concept that mountain topography is extremely impacted by active tectonics along the fault zone. This study result indicated that southern part of the Mae Ping fault zone is high tectonic activities. |
