国际地震学及地球内部物理学协会(IASPEI)在1977年8月大会上通过决议:“鉴于全球台站记录到的地震图是研究地震和地球构造的基础,而早期的地震图由于战争,灾害及变质多有损失;因此,有必要在各台系统地搜集并照像复制重要地震的地震图,以保存并可通过世界资料中心(WDC)取得。IASPEI 强烈要求全球地震台站与复制计划合作,在台站现场提供历史地震图及有关资料,以便照像复制。”随后,IASPEI 所属资料交换委员会建立了复制地震图工作组。
The International Seismological and Geophysical Society (IASPEI) passed a resolution at the General Assembly in August 1977: “Since the seismograms recorded by the global stations are the basis for the study of earthquakes and the earth’s structure, the early seismograms were destroyed by war, disasters And the metamorphism is more and more lossy; therefore, it is necessary to systematically collect and photograph the seismograms of important earthquakes in each system for preservation and retrieval through the World Data Center (WDC) .IASPEI strongly urges the global seismic stations to cooperate with the replication plan , To provide historical seismograms and related information at the station site for photographic reproduction. ”Subsequently, the IASPEI-affiliated clearing house established the Working Group on the Duplication of Seismograms.
