对1900~2002年全球记录到的震级M≥4.0地震震中,利用IGRF(国际地球参考场)国际参考模型确定地磁场的特征。研究了主要地震活动带的地理学和内源引发的基本地磁场几何学之间的关系,查明了不同构造类型的地震活动带全球分布与地磁偏角或地磁场东-西向分量分布之间的构造对应。
From 1900 to 2002, the global M≥4.0 earthquake epicenter was recorded, and the characteristics of geomagnetic field were determined by using the international reference model of IGRF (International Earth Reference Field). The relationship between the geology of major seismic belts and the intrinsic geomagnetic field geometry is studied. The distribution of earthquakes of different tectonic types and the declination of earth’s magnetic field or the distribution of east-west components of geomagnetic field Corresponding to the structure.
