National Information Service for Earthquake Engineering -- Caltech Branch

国家地震工程信息服务（NISEE）的建立是为了方便收集、组织和传播与地震工程相关的信息给不同的用户群体，包括研究人员、执业工程师、教育工作者、政府官员和公众。NISEE目前有两个分支机构；一个在加州理工学院，一个在加州大学伯克利分校。除了在全国范围内发挥作用外，加州理工学院分部还是南加州地区地震工程和地震安全相关专家的大型活跃社区的资源。该处在强震研究领域采取了一项主动行动。一个特殊的强震中心已经建立，以满足参与强震数据采集和分析以及风险评估、地震危害确定、结构性能分析和规范开发等领域的个人日益增长的需求。加州理工学院分院也有一个图书馆收藏和资源，对公共政策和地震准备领域的人很有用。

The National Information Service for Earthquake Engineering (NISEE) was established to facilitate the collection, organization, and dissemination of information related to earthquake engineering to various user groups including researchers, practicing engineers, educators, public officials, and the general public. There are presently two branches of NISEE; one located at Caltech and one located at U.C. Berkeley. In addition to its national role, the Caltech Branch is a resource for the large and active community of earthquake engineering and seismic safety related specialists in the Southern California region. The Branch has undertaken an initiative in the area of strong-motion studies. A special Strong-Motion Center has been established to meet the growing needs of individuals involved in strong-motion data acquisition and analysis and those in such fields as risk assessment, seismic hazard determination, structural performance analysis, and code development. The Caltech Branch also has a library collection and resources that are useful to those in the areas of public policy and earthquake preparedness.
