| 摘 要： | 通过对大气总温度资料的分析，认为１９９８年１月１０日张北地震前几天，震区及其周围的增温异常是一种临震前兆。异常的空间由显示，震中区及其附近为强异常区，并且被弱异常区所包围；该次地震可能是ＮＷ向的张家口－北京－蓬莱断裂带向西扩展活动所致，同时也与尚义－多伦等ＮＥ向断裂的活动有关。总温度等值线的系列演变图概略的反映出了应变能的积聚－扩展－释放的全过程。

| Abstract: | Analysing the data of the total atmosphere temperature,it is discovered that anomalous increase of atmosphere temperature a few days before the Zhangbei MS6.2 earthquake on Jan.10,1998 in epicentral region and its surrounding areas is a kind of impending earthquake precursor.Space distribution of anomalies shows that epicentre of the earthquake is in strong anomaly area which is surrounded by weak anomaly area;the earthquake may be caused by extension of Zhangjiakou -Beijing -Penglai fault of NW towards the west and related to activity of Shangyi -Duolun NE fault etc.at the same time.Development of the total temperature isopleths reflects summarily the process of the accumulation,the expansion and the release of strain. |
