CRAVITY VARIATION IN NORTHEAST AREA OF BEIJING AND DATONGYANGGAO EARTHQUAKE

    Graphical Abstract
    • Abstract
  • This paper, basing on the reliable reiteration and art ificial seismic sounding data, discusses the tendency anomalous variation in gravityin this area and the relation between the character istics of deep crustal structure and seismic activity.This area is a local crustal uplift area, low velocity interlayer exists both in upper oust and lower one.These tendency anomalous variations in gravity field are right the results of variations in crust stress field and deep crustal matter in this area.
