The effects of major structural features in Western China on explosion seismograms

PDF Version Also Available for Download.

Description

Synthetic explosion seismograms have been calculated on paths from Lop Nor to the NIL station in northern Pakistan, from NIL to Lop Nor, and from Lop Nor to the TLY station in the Baikal Rift. Computational studies were done of the influence on the character of the seismograms of major structural features such as sedimentary basins, topography associated with the Himalayas and the Tibetan Plateau, roughness of the Moho, and the presence of a deep Moho depression under the Tibetan Plateau, roughness of the Moho, and the presence of a deep Moho done with a 1-Hz Kelly waves source and ... continued below

Description

Synthetic explosion seismograms have been calculated on paths from Lop Nor to the NIL station in northern Pakistan, from NIL to Lop Nor, and from Lop Nor to the TLY station in the Baikal Rift. Computational studies were done of the influence on the character of the seismograms of major structural features such as sedimentary basins, topography associated with the Himalayas and the Tibetan Plateau, roughness of the Moho, and the presence of a deep Moho depression under the Tibetan Plateau, roughness of the Moho, and the presence of a deep Moho done with a 1-Hz Kelly waves source and 500-m resolution. Uniform elastic constants and frequency-independent quality factors, Q{sub p} and Q{sub s}, were used in each of three materials: basin sediments, crust, and mantle. The deep basins which due to the generation of large-amplitude Rayleigh waves at source-ward basin edges. In simulations done with the effects of anelastic attenuation included, the amplitude of passage across the 800-km-wide Tarim Basin on the Lop Nor -> NIL path but not on the 200-km path across the basin that straddles the Lop Nor -> TLY path.
