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

项目摘要NARS-BAJA：在加利福尼亚州海湾周围部署宽带地震仪器为期5年NARS-BAJA是沿着下加利福尼亚半岛和墨西哥索诺拉省部署地震仪器的5年。该网络填补了加利福尼亚州和墨西哥南部现有地震仪器网络之间的空白，来自NARS-Baja的地震数据是约束地壳和地幔结构和研究加利福尼亚州海湾地区地震断层的关键，那里正在发生活跃的裂谷作用。NARS-BAJA涉及加州理工学院(美国帕萨迪纳)、CICESE(Ensenada.墨西哥)和乌得勒支大学(荷兰乌得勒支)。NARS-BAJA的第一批地震仪器将于2001年10月安装。NARS-BAJA网络与通常由国家科学基金会PASSCAL计划资助的其他被动震源部署有许多相似之处。然而，NARS-BAJA在某些方面表现突出。(1)NARS-BAJA将至少运行5年，以确保建立一个大型地震数据库。(2)NARS-BAJA弥补了加利福尼亚州目前的宽带网络和墨西哥南部的UNAM网络之间的地震台之间的差距。与这些网络结合在一起，NARS-BAJA在墨西哥和加利福尼亚州的构造活跃的太平洋边缘产生了一个史无前例的3000公里长的阵列。(3)NARS-BAJA数据一旦收到和检查，就将通过互联网从IRIS数据中心获得。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.
