【摘要】 选用三峡遥测地震台网和湖北省数字测震台网共同记录到的发生在三峡地区的231次地震事件(2007年6月—2009年12月,MSL≥2.0),对两个台网所确定的地震震级进行对比研究,结果表明用三峡遥测地震台网资料得到的地震震级偏大:2.0≤MSL<2.5的地震,MSL比MLH大0.16级;2.5≤MSL<3.2地震,MSL比MLH大0.11级;MSL≥3.2地震,MSL与MHL基本相等。更多还原

【Abstract】 A comparative analysis of the 231 earthquakes(MSL≥2.0)in the Three Gorges area recorded by both the telemetry seismic network in Three Gorges and the digital seismological network of Hubei province from June 2007 to December 2009 was carried out.The results show that the average magnitude from the telemetry seismic network in the Three Gorges is larger than that from the digital seismological network of Hubei province,as 2.0≤MSL<2.5,MSL is larger than MHL by 0.16 magnitude;as 2.5≤MSL<3.2,MSL is larger than MHL by 0.11 magnitude;as MSL≥3.2,MSL almost equals to MHL.更多还原
