摘要: 通过对调制比预报地震方法进行改进,并使用改进后的地震调制比Rm10对华北地区进行空间扫描。结果表明,中强地震前1~3年,未来震中周围通常出现Rm10中期异常区, 具有较好的中期预报效果。

Abstract: The prediction method of seismic modulating ratio is proved in this paper. The seismicity dataare used to space scanning in North China byuse of the proven method of seismic modula ting ratio Rm10. The result show sthat in mid-term about 1~3 years before most strong earthquakes there are obviously anomaly zones of Rm10 in the neighborhood of epicenter in general. This method has very good effectsin mid-term earthquake prediciton.

Key words: Seismic modulating ratio, Tidal generation force, Space scanning, Mid and short term earthquake prediction
