| 摘 要： | 研究了1992年福建省南日岛5.2级地震序列特征,认为这是一次孤立型地震,震前存在多学科的前兆异常,异常群体特征具有长、中、短临阶段性及形态复杂性.地震学异常持续时间长,前兆学科短临异常突出,可能是少震区地震前兆的特点。

| Abstract: | Study on the characteristics of a M=5. 2 earthquake sequence at Nanri Island, Fujian Province, in 1992 suggests that it is an isolated earthquake. Before the earthquade, there were multidisciplinary precursory anomalies, which were of long-mid-short-and temporal range characters and were complex in shape. Moreover, the seismicity anomaly was lasted in a long time, and short-range precursory anomalies appeared stricking. They may be the characteristics precorsors of earthquake in the area with rare earthquakes. |
