The earthquake distribution and the resistivity structure in the Chinese mainland (I)

  • Chang-Fang Xu


This paper is the first one of a series of three papers on the fluid evolution of the crust-upper mantle and the causes of earthquakes. Their relationship between the deep-seated fluids and the seismic activities are discussed from aspects of their macoscopic scale, microscopic mechanism and dynamic behaviors in the three papers respectively.

Based on magnetotelluric sounding (MT) measurements conducted by Chinese geophysicists in more than 20 years, the maps of the upper mantle conductive layer (MCL) with a buried depth of >50 km and the crustal conductive layer (CCL) with a buried depth of >15 km in the Chinese mainland are presented in this paper. The resistivity structure, the causes of conductive layers in crust-mantle and the relationships between earthquake distribution and conductive layers are discussed.
