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 M_S8.0 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.
