JCZ-1甚宽频带数字地震仪地震记录特征
|
摘要
分析讨论了ＪＣＺ－１甚宽频带数字地震仪在武汉地震台观测记录的典型特性，并与该台短、中、长周期模拟地震仪的同步观测资料作了比较分析，结果表明，其地震震相记录清晰、丰富。应用ＪＣＺ－１甚宽频带数字地震仪能有效地提高地震台的地震监测能力和全球大震速报质量。
In this paper, the typical character of JCZ-1 ultra broadband digital seismometer shown in seismic record at Wuhan station is discussed and analyzed. After comparing with the simultaneous observation results obtained from the analogue record seismometer (short, middle and long period), it shows that the seismic phases of JCZ-1 are clear and rich even more. The application of the JCZ-1 to the seismic observation can obviously raise the monitoring ability of seismostation and the quality of quick report for large earthquakes.
