- 摘要:
- 运用双差定位方法对2012年7月发生在江苏省宝应县的4.9级地震序列重新进行精定位处理。精确定位结果与原始定位结果比较发现，精定位后的震中位置更加集中，并呈条带状分布，与现场烈度保持一定的相似性，震源深度集中于10km与14km附近两个区间，相比原始定位结果更加收敛。
It is relocated the earthquake sequence of M4.9 which happened in Baoying County ,Jiangsu Province in July 2012 by using the double difference location method. Precise positioning results with the original mapping results, fine positioning of the location of the epicenter is more concentrated, and banded distribution. maintained a certain degree of similarity with the field intensity, focal depth focus on 10KM and 14KM near two intervals. Compared the original positioning results more convergence.
