| 摘 要： | 在不少震例中,临震前地壳出现气体异常,震前地下岩石受力产生裂隙,隐藏在地层中的CO2、CH4等温室气体逸出地表或水面。利用卫星光谱分析技术对断层逸出气体组分含量和总量进行监测,筛选出能够反应地震孕育过程中地下逸出气体异常演化特征的参数,建立地震短期预测的动态演化方法。对于认识震前地表气体异常机理,了解流体震兆的演变规律与这些气体异常的动态关系,改善卫星遥感地震预测,是很必要的。

| Abstract: | Before the occurrence of strong earthquake,there are abnormal gas effusions from lithosphere.It can be monitored and analyzed for earthquake prediction research.In this paper,the satellite remote sensing method,physical basis of satellite optical spectrum analysis,disturbance factors and how to improve the resolution of satellite data,as well as the mechanism of the application of the gas effusion from faults in earthquake prediction are introduced.Satellite remote sensing for gas effusion from faults may be a hopeful way to monitor earthquake precursors as well as an approach in short-term earthquake prediction. |
