引言在过去的7年里,位于西雅图的IRIS数据管理中心的数据存档已成为地震学家为研究地球内部和震源情况而收集地震数据的数据源。在这些数据存档中,包含有执行IRIS PASSCAL项目期间部署的临时地震台站的数据,有IRIS全球地震台网的永久台站的数据,数字地震台网联盟的其他合作成员组织台网的数据以及来自美国地质调查局运行的早期数字台网的重要数据,由于中心还提供了获取这些波形数据有效方法,而成为世界上最大的地震波形数据的汇集中心。在大地震发生后的几小时内,地震学 Introduction The data archiving of the IRIS Data Management Center in Seattle for the past seven years has become a data source for seismologists gathering seismic data to study the earth’s interior and hypocenters. These data archives include data on temporary seismic stations deployed during the IRIS PASSCAL project, permanent stations on the IRIS Global Seismic Network, data on other cooperative member organizations’ networks of the Digital Seismic Network Consortium, and Important data from early Digitalis networks run by the US Geological Survey became the largest collection center for seismic data in the world as the center also provided an efficient way to access these waveform data.
