【摘要】 2009年3月间,在中国境内共发生三次4级微地震,本文利用NCEP(www.ncep.noaa.gov)遥感数据依据天体引潮力变化周期提取异常增温信息对其进行分析。结果表明:依据天体引潮力变化周期获得的增温图像呈现出震前异常增温经历:起始→高峰→衰减→再升温→平静的演变过程,该过程反映地震构造由初始微动破裂→扩张破裂→结构调整→地震爆发→平静的一般过程。从引潮力的改变就是温度开始变化的起点,表明天体引潮力对地震构造活动具有一定的影响,但这种影响不是突然的而是连续的,当达到临界点(温度由最高-下降点)就可能诱发地震。更多还原

【Abstract】 The three micro-earthquakes(Ms<5) took place in China in March 2009 were studied with their NCEPs(www.ncep.noaa.gov) remote sensing temperature data and according to the cyclical changes in tidal force of celestial bodies to analyze their abnormal warming.The results indicate that the tidal force of celestial bodies has a triggering effect on the activity of tectonic.The temperature abnormal increase varied with the cycle calculated from changes in tidal force of celestial bodies:initial temperature rise→enhancement→reaching peak→attenuation→return to baseline.This evolution of changing indicated the fault activities under tectonics stress:tectonic movement extrusion→rock micro-breakage→rock breaking enhancement→energy accumulation→shaking→tranquil.Tidal force of celestial bodies has a certain influence on tectonic activity,the impact is not sudden but a continuous,when it reached a critical point(temperature from the highest to lowest point) it may induce an earthquake.更多还原
