  ABSTRACT: In order to find geomagnetic anomalies associated with Ms ≥ 6.0 strong earthquakes in Yunnan area, geomagnetic harmonic wave amplitude ratios with Z, H and D components in TCH, THJ, CHX and YOS stations were analyzed. It was found that geomagnetic amplitude ratio of Yzhx experienced a trend of decrease and increase before most of strong earthquakes. Moreover, these variations in different periods were inconsistent and no similar changes appeared for Yzhy, which may relate to fault-zone conductivity variation and seismogenic structure.
