摘要
从嵊州、新昌地震 (1998 0 8 17T 1∶4 6ML4 5)的地震地质构造环境、卫星热红外异常与近地表大气增温异常等三个方面 ,进行了研究。认为地震前几日 ,震区及周围大面积的突发性低空大气增温异常与卫星红外异常是一种临震前兆 ,并总结了增温异常的时空演变规律与地震活动的关系。
Based on the informations of seismogeological structural environment, and satellite thermo infrared and lower atmosphere temperature increase anomalies of Chengzhou Xinchang earthquake of Aug. 17,1998, M L4.5, it is considered that this abrupt anomalies appeared in the epicentre and adjacent area prior to the earthquake is a imminent precursor. The relation between the time space evolution law of temperatural increase anomaly and seismicity is summarized.
