Abstract: At present, the earthquake monitoring system on Earth′s surface mainly observes relative change of single point. Owing to lower density of the observational stations, the coverage of data cannot meet the needs of information serving the earthquake prediction. The development of space survey technique, which has advantages of vast coverage, huge information, well dynamics and high distinctiveness delivers a new way for earthquake monitoring. GPS data and INSAR data play an important role in the field of geo-research and earthquake monitoring. The application of these space techniques will make success in the field of earthquake monitoring and geo-researches further more.

Key words: Space survey techniques, Earthquake monitoring, Crust deformation
