国际地震中心(ISC)是一个国际性的非政府机构,建立的目的是搜集世界范围的地震信息,包括仪器记录数据和宏观地震资料。通过对这些数据的分析,可得到全球尺度上的最精确和最完全的地震位置和震级。这些地震的震源位置、震相数据和宏观地震资料,均在地震发生后两年之内以月刊和半年一次目录的形式出版。这些数据也存储在计算机磁带上,其最后结果是一部详细的世界地震史。由于我们正在书写一部特殊的历史——地球的地震历史,所以有必要回顾一下 ISC 是怎样随时间发展的、它的功能是怎样不断改进的。我还要说明 The International Seismological Center (ISC) is an international non-governmental organization set up to collect worldwide seismic information, including instrumentation data and macro-seismic data. By analyzing these data, the most accurate and complete seismic position and magnitude at the global scale are available. The source location, seismic facies data and macro-seismic data of these earthquakes are published in monthly and semi-annual catalogs within two years after the earthquake. These data are also stored on computer tapes, and the end result is a detailed history of world earthquakes. Since we are writing a special history, Earth’s Earthquake History, it is necessary to review how the ISC developed over time and how its function is continually improved. I will explain
