备注

运用“形变速率累加”法对川滇地区选取的5个算例进行了解算。结果 表明:通过对较连续的异常“孤立点”进行积分后的形变速率累加图,在异常的识别与表达上更具有实用性和直观性,该方法适用于川滇地区跨断层水准资料,可作为地震的中期预报指标。

Using deformation rate accumulation method,we calculated the selected five examples in Sichuan-Yunnan region. The result showed that it is more practicality and intuitive on abnormal identification and expression on deformation rate accumulation chart after integrating for continuous abnormal outlier. This method applies to cross fault leveling data in Sichuan-Yunnan region,and can be as the medium-term indicator for the medium-term earthquake prediction.
