摘要
通过对天水台 64地震仪记录的甘肃碌玛曲地区一系列小震群的震相分析 ,发现该区域地震记录波形特别 ,而导致错误分析。为说明该震区地震波的记录特点 ,我们对震中距基本相同的宁夏青铜峡 ,四川北川地震进行了对比分析。认为碌码曲震区地震波形独有特点 ,各震区地震有各自的记录特征。
Through analysing seismic phases of a series of the small earthquake clusters in Luqu Maqu area,Gansu province with the 64 type seismograph at Tianshui seismic station,We find the regional seismic recording waveform are so special that with general seismic analyse method it is always lead to mistake results.For explaining the seismic recording features in Luqu Maqu area,we analyse and compare these records with those of Qingtongxia earthquake in Ninxia province and Beichuan earthquake in the North Sichuan area,which have the same epicentral distance with Luqu Maqu earthquake to Tianshui seismic station.Through this comparative analyse,we consider the recording waves are special on Luqu Maqu seismic area and the recording features are different in different seismic areas.
