空间观测技术在地震监测中的应用

Application of space survey techniques in earthquake monitoring

当前地面地震监测系统主要观测单点的相对变化,由于观测台站密度低,观测资料覆盖面小,不能满足地震预测所需的信息。空间观测技术的发展提供了新的地震监测技术和方法,卫星空间监测技术具有覆盖面广、信息量大、动态性好以及分辨率高等优势,因而可提供更为丰富的地震前兆信息。岩石实验的结果和一些应用研究的结果显示,空间观测技术在地震监测中具有优越的应用前景。

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.
