摘要:
利用我国地磁观测台网每天的子夜均值资料,运用高性能计算技术,建立了中国大陆地磁场动态演化模型。利用该模型,研究了2008年5月12日汶川8.0级地震前后中国大陆地磁异常场动态演化。结果表明:地震前后地磁异常场变化特性较明显,具有显著的阶段性特征,这可能反映了地震不同孕育阶段的特征。
Abstract:
On the basis of the mid-night mean value from China Geomagnetic Observation Network,we establish the dynamic model of geomagnetic field variation by parallel computing technology.Then we study the characteristics of the dynamic geomagnetic variation of anomalous field before and after the Wenchuan MS8.0 earthquake on May 12,2008 in Chinese mainland.The result shows that the geomagnetic anomalous field changes significantly in different stages.This may reflect the earthquake-preparation characteristics in different stages.
