摘要:
利用NGDC-720模型计算云南地区岩石圈磁场X,Y,Z分量,分析岩石圈磁场分布特征,并从空间分布及强度统计两方面研究1970—2019年云南省内31次MS≥6.0地震与岩石圈磁场分布之间的关系。结果表明:云南地区主要断裂的展布与岩石圈磁场分布有着较好的对应关系,且研究区内MS≥6.0地震大多分布在负值异常区或正负异常区的分界处。
Abstract:
Firstly,using the NGDC-720 model,we calculated the X,Y,Z components of the lithospheric magnetic field in Yunnan area,and analyzed the distribution characteristics of the lithospheric magnetic field.Then,we studied the relationship between the epicentral location of the 31 MS≥6.0 earthquakes in Yunnan Province from 1970 to 2019 and the distribution of the lithospheric magnetic field from two aspects of spatial distribution and intensity statistics.The results show that the distribution of major faults in Yunnan area has a good correspondence with the distribution of the lithospheric magnetic field,and most MS≥6.0 earthquakes are distributed in the negative anomaly area or the boundary of the positive and negative abnormal areas in the study area.
