MARGINS: NARS-Baja: A Five-Year Deployment of Broadband Seismic Instruments around the Gulf of California

项目摘要：在加利福尼亚湾周围部署宽带地震仪器5年NARS-Baja是在墨西哥的下加利福尼亚半岛和索诺拉省沿着部署地震仪器5年。该台网填补了加州和南墨西哥现今台网之间地震仪器的空白。来自NARS-巴哈的地震数据是约束地壳和地幔结构以及研究正在发生活动裂谷的加州湾地区地震断层的关键。NARS-Baja项目涉及加州理工学院（美国帕萨迪纳）、CICESE（恩塞纳达）、墨西哥）和乌得勒支大学（乌得勒支，荷兰）。NARS-Baja的第一批地震仪器将于2001年10月安装。NARS-Baja网络与其他被动源部署有许多相似之处，这些被动源部署通常由美国国家科学基金会的PASSCAL计划资助。 然而，在某些方面，NARS-Baja脱颖而出。(1)NARS-Baja将运行至少5年，以确保建立一个大型地震数据库。(2)NARS-Baja弥补了加州现今宽带网络与墨西哥南部UNAM网络之间地震台站的差距。 与这些网络相结合，NARS巴哈产生了前所未有的3000公里长的阵列沿着构造活跃的太平洋边缘的墨西哥和加州。(3)一旦收到和核对国家遥感系统巴哈数据，将通过因特网从综合资源信息系统数据中心提供这些数据。这促进了整个研究界的参与。

Project AbstractNARS-Baja: A 5-year Deployment of Broadband Seismic Instruments Around the Gulf of CaliforniaNARS-Baja is a 5-year deployment of seismic instruments along the Baja-California peninsula and Sonora province in Mexico. This network fills a gap of seismic instrumentation between present-day networks in California and southern Mexico Seismic data from NARS-Baja is key to constrain the structure of the crust and mantle and to study earthquake faulting in the Gulf of California region, where active rifting is taking place. NARS-Baja involves collaboration between the California Institute of Technology (Pasadena, USA), CICESE (Ensenada. Mexico), and the University of Utrecht (Utrecht, The Netherlands). The first seismic instruments of NARS-Baja will be installed in October of 2001.The NARS-Baja network shares many similarities with other passive-source deployments, commonly funded by the PASSCAL program of the National Science Foundation. However, in some aspects NARS-Baja stands out.(1) NARS-Baja will be in operation for at least 5 years to ensure that a large seismic database is constructed.(2) NARS-Baja bridges the gap in seismic stations between present-day broadband networks in California and the UNAM network in southern Mexico. In combination with these networks, NARS-Baja yields an unprecedented 3000-km long array along the tectonically active Pacific margin of Mexico and California.(3) The NARS-Baja data will be made available via the Internet from the IRIS data center as soon as it is received and checked. This promotes involvement by the entire research community.
