中文摘要：

2011年3月10日中国云南盈江发生5.8级地震,3月11日日本本州岛东海岸附近海域发生9.0级地震。2011年3月7日、8日云南永胜地磁台站观测到了舒曼谐振前4阶振幅异常增大。本文建立了基于三维时域有限差分方法的舒曼谐振模型,利用该模型对盈江地震对永胜站观测到的舒曼谐振影响进行了数值分析。通过对实验和模拟结果进行分析,认为此次云南永胜观测到的舒曼谐振异常不仅与日本地震相关也可能与云南盈江地震相关。

英文摘要：

On March 10,2011,an M_s5.8 earthquake struck in Yingjiang,China.On March 11,2011 an M_w9.0 earthquake struck near the east coast of Japan.Yongsheng geomagnetic station in Yunnan observed that the amplitude of Schumann resonance increased exceedingly on March 7～8,2011.The Schumann resonance observations affected by Yingjiang earthquake in Yongsheng station were numerically simulated based on the mechanism of Schumann resonance anomalies and finite difference time domain method.The results show that the Schumann resonance anomaly is probably related to both the Yingjiang earthquake and Japan earthquake.
