Morphotectonic Analysis along the Eastern Chiang Khong Basin, Chiang Rai, Northern Thailand

Chiang Khong Basin (CKB) is a northeast-southwest active basin in Rai province, northern Thailand. The bounded to the east by numerous fault segments of Mae Ing Fault Zone (MIFZ), where they have triggered several previous earthquakes and vicinities. Although slip MIFZ has some earthquakes, deformation landscape affected tectonic processes mainly unknown. According uniform lithologic climatic conditions across MIFZ, we rely on developing high-resolution digital elevation models satellite images identify lineaments lines evaluate activity along eastern CKB. We conducted morphotectonic analysis primary geomorphic indices channel-hillslope coupling (drainage patterns, mountain front sinuosity (Smf), stream-length gradient index (SL)) define zones tectonics. These values efficiently imply degree activity. Our reveals that most drainage patterns are dendritic, trellis, rectangular, which indicate joints minor faults. Smf vary between 1 2.4, SL reach peak near toe segment’s line. combination suggests CKB experiences high level tectonics impacted MIFZ. study highlights morphometric estimate region.
