Several concerns of national importance have surfaced in recent seismic code decisions in the Wasatch Front. This study will use seismic risk analysis to elaborate relevant features of these decisions. Particular attention will be paid to: (1) systematic differences of opinions on geoscience and structural engineering issues; (2) differences among different types of buildings in cost upgrades for designing to higher seismic code levels; (3) potential implications of high soft surfacial soil site dynamic amplification factors; and of (4) strengths and weaknesses of diverse ways of structuring seismic risk statistics in order to yield a decision. A model application to the Wasatch fault will assist in developing these seismic risk methods. Risk statistics will also be produced for the Los Angeles region to put Wasatch Front statistics into perspective.

几个具有国家重要性的问题已经浮出水面 最近瓦萨奇前线的地震法规 本研究将以地震危险性分析来阐述 这些决定的相关内容。 特别 注意：（1）系统性差异 对地球科学和结构工程的意见 （2）不同类型的差异 建筑物的成本升级，以设计更高 抗震规范等级; (3)高软表土层的潜在影响 站点动态放大因子;以及（4） 不同结构化方式的优缺点 地震风险统计数据，以便做出决策。 对瓦萨奇断层的模型应用将有助于 开发这些地震风险评估方法。 风险统计 还将为洛杉矶地区制作 Wasatch Front的统计数据。
