Recently, the China Earthquake Administration announced the results of the 2017 Earthquake Prevention and Mitigation Science and Technology Achievement Awards. Professor Gan Weijun of the Institute of Geology won first prize for “Research on the Three-dimensional Crustal Deformation of the Tibetan Plateau and the Strong Ground Motion Research of the Wenchuan Earthquake Based on GPS Observations.” Third prizes were awarded to Professor Ren Zhikun for a study on “The Role of the Wenchuan Earthquake in the Evolution of the Geomorphology” and to Professor He Honglin for work on the "Technologies of Numerical Seismic Tectonics Research."

The team of Prof. Gan Weijun made full use of the “GPS Observations of the China National Crustal Movement Observation Network” (Phases I and II), performing many investigations of the crustal deformation and tectonic movement of the Qinghai–Tibetan Plateau based on strong ground motion data of the 2008 Wenchuan earthquake. The research results not only had important scientific significance for better understanding of the kinematic characteristics and the dynamic mechanism of the uplift and expansion of the Qinghai–Tibetan Plateau, but they also provided quantitative crustal deformation and tectonic movement parameters for the determination of regional mid- and long-term seismic hazards.

The team of Prof. Ren Zhikun combined the methods of seismic geology and tectonic geomorphology to quantify the effects of strong earthquakes on the uplift and erosion of geomorphology, establishing a quantitative model for the change of erosion rate under the influence of strong earthquakes. It is of great importance to understand the role of strong earthquakes in the uplift of the Qinghai–Tibetan Plateau, and such knowledge is beneficial in coupling seismic geology and tectonic geomorphology.

The team of Prof. He Honglin established a set of methods for extracting structural geomorphology and ancient earthquake identification based on high-precision, high-resolution terrain and geomorphological data, which is pioneering, innovative, and highly topical work. It is of fundamental importance to understand the characteristics of tectonic features, response laws of repeated strong earthquakes, and evolution of geomorphological patterns.

Congratulations!
