Active Tectonics Assessment Using Geomorphic and Drainage Indices in the Sertengshan, Hetao Basin, China

Geomorphic parameters, which reflect the migration of drainage divide responses, are widely used to assess tectonic activity. There have been several large earthquakes in history Hetao Basin, within Sertengshan Piedmont Fault is important. This study highlights certain references for regional seismic risk assessment. Few studies conducted on area from perspective geomorphic parameters. In this paper, ksn, HI, and Vf were obtained indicate activity area, Gilbert metrics extracted explore state basin. The results show that varies spatially strong western part southern region northern corresponding turning point fault. Most prime old stages geomorphological evolution, whereas some areas juvenile stage. stage was mainly concentrated region, younger than region. Overall, tectonically active affected by Fault. migrated northwest, while central eastern parts tended move southward. We suggest influenced tends towards direction lower
