earth observation from space & crustal deformation laboratory

History and Mission

Earth observation from space & crustal deformation laboratory was established on the basis of former remote sensing laboratory of IGL, CEA, which founded in early 1980s. There are three study groups (INSAR, GPS, Crustal Deformation) in this laboratory, belonging to State Key Laboratory of Earthquake Dynamics. Earth observation technology(GPS, INSAR, satellite remote sensing, etc.) from space is the main direction of this laboratory.  

The mission of this laboratory focused on basic and applied studies of remote sensing technology in seismology and other relevant fields. It uses the multi-satellite sensor, the fusion technique of multi-source information, and GIS technique to perform research of continental dynamics, crustal deformation, seismic source characteristics, quick investigation assessment of disasters, etc,.

It uses InSAR, PS/CR-InSAR, Combination of active tectonic and other data, analysis of crustal movement and tectonic deformation of the temporal evolution of images of continental tectonic stress field, plate geometry and kinematics, activity block movement state. Inversion of the crust and upper mantle three-dimensional fine velocity structure, kinematics and dynamics to carry out research in China, environmental characteristics of the seismogenic fault activity and the strong relationship between earthquake preparation studies for earthquake prediction research mechanism and physical basis.

It uses GPS to obtain contemporary tectonic strain rates of Chinese continent from analyzing crustal motion inferred from GPS velocity field. It carry out the research of combination GPS with InSAR, taking advantage of their complementary strengths and of minimizing their respective weaknesses, exploiting the complementary aspects by overcoming the limitations inherent in the use of each technique alone, to obtain high-precision, large range, high spatial and temporal resolution observations of crustal deformation.  To carry out the integration research of  thermal infrared, optical image, radar, and other multi-source remote sensing, seismo-ionospheric disturbance characteristics based on GPS TEC and electromagnetic satellites, and its application in theoretical study of seismology, to provide the physical basis for the stereoscopic seismic monitoring.

Faculty, Staff

Research Center currently has 11 full-time staff, of which 3 researcher , associate researcher , 4. Doctoral and postgraduate 13, is a style of rigorous and energetic team.

Facilities and Research

The facilities of the laboratory include hardware and software for image processing and geospatial analysis, as well as a wide array of ancillary and supporting equipment.

A large suite of applications software provides state-of-the-art capabilities for image processing, mapping, modeling, statistical analysis, and visualization. Such as ENVI, GAMMA, Erdas, etc,.

 There are hundreds of sets of GPS receivers, InSAR Corner reflector, several sets of seismology, InSAR, GPS processing software, and three-dimensional laser scanner, spectrum analyzer and other auxiliary facilities. Since 2003, The polar-orbiting satellite station was set up on April 15, 2003 which receives real-time data from NOAA series and FENGYUN series satellites. The daily quantity of incoming data is beyond 4 Giga Bytes in 50 stripes from 7 satellites, each file may account for up to 80-150 Mega Bytes. INSAR research group has taken Haiyuan fault Qilian Mountains into regions, metropolitan area northwest of Beijing and the Changbai Mountain area Yanhuai Basin region of three volcanic Tianchi corner reflector array InSAR comprehensive observation area, laid the corner reflector 130 sets of GPS research group laid in the earthquake, a number of earthquake sets of GPS mobile observation station, the change of surface deformation for earthquake provided a first-hand information. Laboratory in recent years undertaken a number of 973 projects, major projects, the State Development and Reform Commission, the National Natural Science Foundation and the General Program, seismic industry specific items, technology platform, construction projects, scientific and technological support projects, the Ministry of Finance and the entry of international cooperation in specific projects. According to incomplete statistics, the national project funded by 2005-2007 more than 2000 million.
