大连地震台面波震级偏差分析与校正

ANALYSIS AND CORRECTION ON SURFACE WAVE DISPERSION IN DALIAN SEISMIC STATION

中国地震台网中心提供了一个试算的大连地震台面波震级台基校正模型。基于该模型,我们对1985年至2003年大连地震台记录的共计1357次地震进行了面波震级台基校正试算,按照不同震中距、不同震级、不同方位角分别进行了讨论,得到大多数情况下大连地震台单台实测面波震级小于国家台网面波震级的结论。

The China Earthquake Networks Center provides a trial of Dalian surface wave magnitude platform calibration model, based on the model, the 1985 to 2003 in Dalian seismic station total 1357 earthquakes of surface wave magnitude platform trial and error correction. For platform in Dalian seismic surface wave magnitude correction, according to the epicentral distance, different earthquake magnitude, range angle are discussed respectively.
