摘要
本文详细的介绍了常熟—太仓5.1级地震前,震中距100公里范围之内的太湖周围地区,以地下水动态为主的水位、水温、水化学组分等,在中、短期及临震阶段较丰富的异常资料。并从异常时间明显的阶段性与同步性;异常空间的展布地域较集中,并且异常的出现顺序由震中区附近向外逐步扩展,而结束的顺序则反之的规律性;异常形态的丰富及复杂性;异常的幅度和范围中期阶段大、短期阶段小等四个方面,对异常的特征及其意义进行了分析总结。
This paper introduced in detail a great number of the medium-, short-term and impending anomaly data of the underground water dynamics before Changshu-Taicang As=5.1 earthquake, including the water level, water temperature and hydrochemical composition of the underground water. Authors also analyzed and summarized the anomalous features and their singnificance according to the staged character and synchronism of abnormal times. The spatial distrubution of anomalies is relatively concentrative; the occurrence order of anomalies is outward extension from the epicentral region and the regularity of the ending order is contrary; the abnomal form is various and complicated; the anomalous amplitude and range are large in the middle stage and small in the short and impending stage.
