Tectnonic geomorphology is an emerging and fast growing interdisciplinary field during the last couple of decades, focusing on the interplay of tectonics, erosion and climate change in orogenic belts. Tectonics is the major driving force, among three components, in shaping the landscape; accordingly neotectonics, the study of crustal deformation in the most recent geological time scale, holds the key to understanding the making of late Cenozoic topography and landform in tectonic active regions.

With the advance and fast development of new fine-scale remote sensing and precise dating techniques and their applications, tectonic geomorphology, including landscape change in consequence of large-magnitude earthquakes, has thus host remarkable discoveries, ensuing new and more exciting scientific questions, promising a major contribution in fields of disaster mitigation, environmental and climatic changes, and tectonic deformation.

In order to foster promising new research directions of the State Key Laboratory of Earthquake Dynamics,the division of Neotectonics and Geomorphology was established in December 2012 to expand research focus on tectonics and geomorphology.

The main research focus of our faculty members includes strong earthquake and active deformation, and related landform evolution in three spatial and temporal scales: 1) quantitative study of small-scale landforms related to strong earthquake activities at 10,000-year time scale; 2) research of the mechanism and process of landforms related to Quaternary active tectonics at 104-106-year time scale ; 3) research on the formation and evolution of macro-tectonic landforms relevant to neotectonics at 106-107-year scale.

Subdivision research groups:

Research group on strong earthquakes and microtopography. Quantifying the characteristics, processes and evolution of topography, geomorphology and sedimentation relevant with current and prehistoric strong earthquake activities. Integrating research techniques in quantitative geomorphology, structural geology and sedimentology, revealing paleo-earthquake sequence, carrying out basic research on landform shaping process and mechanism of strong earthquake and guiding earthquake prevention and disaster mitigation efforts.

Research group on active faulting and geomorphology. Studying the characteristics, process, and evolution of mesoscale tectonic landforms and the interaction between tectonics and climate, focusing ontectonic landform relevant with active faulting, active folds at 104-106-year time scale, with the aid of terrestrial and airborne light detection and ranging (LiDAR), GPS, InSAR and other earth observation technologies.

Research group on Neotectonics and landforms. Quantifying tectonic deformation, basin evolution and macroscale landform evolution process at 106-107-year scale. Pay attention to the time, extent and rate of surface uplift, erosion and sedimentation and other issues of structural geomorphology on a long time scale, particularly, mountain uplift, basin disappearance and regional landform remolding relevant with the growth and evolution of Tibetan Plateau.

Research group on geomorphic modeling and 3D visualization. Quantifying topographic characteristics of tectonic landforms, building analog and numerical models of landform evolution, elucidating processes of tectonic deformation at orogenic scale, fluvial geomorphology, and seismo-morpholgy, using digital elevation model (DEM) and by means of GIS and numericaltools.
