摘要
对三峡地区数字地震台网中心记录的典型的天然地震、疑炮、一次爆破及一次滑坡等波形进行初步分析后认为 :①数字地震仪器与模拟地震仪器所记录的地震波形特征基本一致 ;②三峡地区数字地震台网中心 2 0 0 3年5月 19日至 2 0 0 4年 1月所记录的多数天然地震事件是非构造型 (由溶洞塌陷引起的陷落型 )
This paper preliminarily analyzes a part of typical waves from the records of Digital Earthquake Observation Station Network Center(DEOSNC) and some good results have been obtained. After compared with wove form of blowing up and a time landslide wave form etc,some conclusions are drawn.First the characteristics of seismic waves recorded by digital seismograph and analogical one are basically coincident with each other.Secondly most of earthquakes recorded by DEOSNC are not the tectonic (may be the collapse) earthquakes.
