摘　　要：ShakeMap可称为地震动制图系统,是一套近乎实时计算地震动并作出地震动图的程序。它是一些子程序和模块的集合,主要程序用Perl语言编写,用MySQL管理文件,最终用GMT作图。最初由加州地震台网构思并完成系统构建,用于地震震情的快速反映,随着中国大陆强震台网的建立和越来越密集台阵的布设,ShakeMap的应用也更受关注。本文深入讲解ShakeMap的工作原理,尝试在国内架构中应用该系统,以便能快速的得到地震震后的地震动和烈度图,供地震工程学家及震灾抢险工作者使用,文中以2003年MS5.9的赤峰地震为例来探讨ShakeMap在国内应用的可能性及应用局限性。ShakeMap is a collection of programs,largely written in PERL programming language.These programs are run sequentially to produce-ground motion maps as well as Web pages and pager/email notifications.In addition to PERL,maps are made using the GMT,and parametric and earthquake-specific data and mapping parameters are stored and queried via MySQL database.ShakeMap is designed to rapidly produce shaking and intensity maps for use by emergency response organizations,local,county,State and Government agencies,public and private companies and organizations,the media,and the general public.We will discuss how ShakeMap works and its possible potential applications by giving an example of Chifeng earthquake with MS5.9.Its limitation is also discussed.
