【摘要】 利用我国地磁台网每天的"子夜均值"资料,应用高性能计算技术,建立中国地磁场动态演化模式,研究汶川5.12地震前后中国地磁异常场逐日演化特征。结果表明:地震前后地磁异常场变化特性较明显,在时间上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。更多还原

【Abstract】 Based on parallel computing technology,firstly to establish a dynamic model of the variation of geomagnetic field in China,the characters of diurnal-variation anomalies of geomagnetic field before and after Wenchuan MS8.0 earthquake are studied.The results show abnormal changes in geomagnetic field are taken place obviously before and after Wenchuan earthquake.It may reflect the different stages of earthquake preparation process.更多还原
