Research Abstract |
Tectonic geomorphic features are carefully analyzed in some areas where long-wave and small-amplitude relieves apparently prove long-term continuous uplifting. However, I observed wide flexural scarps on marine terraces surfaces, height changes of the former shorelines indicating distinct tilting and emerged wave-cut benches indicative of abrupt relative sea-level changes. These tectonic features have been convincingly owing to the activity of marine active faults with episodic crustal uplifts. Active faults on seafloor along plate boundary are resultants of repeated large earthquakes as those on land. It is very important to depict distribution and geometry of active faults based on tectonic geomorphologic method.
