| 摘 要： | 以近年来广东省台站观测资料为基础,总结和探讨了地形变前兆异常指标的辨识方法。由震例总结得到的研究可信度与国内的大致相同。震前异常指标在时间上的协同性表明,不同方法观测到的地形变资料其内在的物理特性是统一的、相互关联的。

| Abstract: | In this paper, the crustal deformation data from observation stations in Guangdong Province are summarised and a method for recognition of the indicators of deformation precursor anomalies is discussed. The confidence level of deformation precursors studied for earthquake cases in Guangdong is roughly coinsident with that in the whole country. The concordance of anomaly indicators before earthquakes in time shows that the internal physical properties of the crustal deformation observed by different methods are uniform and interrelated. |
