由龙羊峡库区无线遥测地震台网资料初步探讨青海共和地震成因

DISUSSION ON THE CAUSE OF THE GONGHE Ms7.0 EARTHQUAKE, QINGHAI,BASED ON THE DQTA OF THE TELEMETRIC SEISMIC NETWORK IN THE LONGYANGXIA RESERVIOR REGION

摘要:

1990年青海共和7.0级地震是构造地震还是水库畜水诱发地震?黄河上游龙羊峡水库周围地区的无线遥测地震台网在8年运行中记录了丰富的地震资料,共和地震后就记录到余震8,145个,为上述问题的研究积累了丰富的资料和数据。近来,特别是1994年,5.0级以上地震在这一地区呈增多趋势。因此,龙羊峡水库周围是值得地震研究人员密切注视和研究的地区。

Abstract:

An earthquake(M_s 7.0)occurred in Gonghe county,Qinghai Province,on Apr.26,1990.Is it a tectonic earthquake or a reservior earthquake? The telemetric seismic network around the Longyangxia reservior has recorded a wealth of earthquake data for the past 8years,only after the Gonghe earthquake,the network recorded 8,145 aftershocks,thus provides rich data for solution of the above-mentioned problem,There have been more and moreMs ≥ 5.0 earthquakes in the region since 1994.Therefore,the Longyangxia reservior region merits seismologists attention and studies.
