新版美国地震区划图源及其参数模型的分析与评述
Comments on the Models of Seismic Source and Parameters Used in the New Edition of United States National Seismic Hazard Maps
【摘要】 2008年版《美国地震危险性图》(本文称"美国地震区划图")采用5种类型震源区模型。本文全面分析了这些震源模型的划分目的、划分原则、基本特征、用途、各类型源间的相互关系,及其地震活动性参数确定的原则与基本方法。评述了美国地震区划图震源区模型及其地震活动性参数确定的特点和存在的问题。以期为我国新一代地震动参数区划图编制提供参考。
【Abstract】 In this paper, we introduce the goals and principles of the five different earthquake source models used in 2008 United States National Seismic Hazard Maps (USNSHM). The routine and the methodology of seismicity parameters obtaining for each source model are discussed in detail. Both significant characteristics and disadvantage of the source and seismicity rate models used in USNSHM are commented here. What we learned from USNSHM is helpful for us to compile the new generation map of seismic ground motion hazard of China in future.
