| contents | Reservoir induced seismic hazard using principal component analysis H. N. Srivastava R. K. Dube Ciencias de la Tierra Induced seismicity dams and earthquakes Empirical orthogonal functions (EOF) associated with the parameters conducive to reservoir inducedseismicity have been computed based on 37 cases throughout the world. It was found that the firstEOF explained 54% variance. It showed a correlation of 0.38 with the maximum magnitude ofearthquakes and had large loadings for reservoir volume and the time lag of the occurrence of thelarges earthquake since the filling of the reservoir. The second EOF which explained about 33%variance however, showe d largest loading for the height of the reservoir but had a correlation ofonly 0.10 with these parameters. By including the maximum magnitude of the earthquake as thefourth parameter, the first two EOF´s explained only about 73% variance as compared to 87% withthe three parameters. The combined influence of the reservoir volume and the time lag appears to bemore important than the height of the reservoir from the view of hazard assessment. 1997 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56836101 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.36 |
