Continued Operation of the Guerrero Accelerograph Network

这一行动是为了继续支持格雷罗台网的运行，并对收集到的数据进行分析。格雷罗加速器台网是1985年安装的，当时是墨西哥沿海30个台站的强震仪器台网。该网络的目的是恢复格雷罗地震空区预期发生的8级地震的加速度图。虽然这场大地震还没有发生，但台网已经获得了许多中小地震的加速度图。在截至1998年底的15年里，该网络记录了738次3级至8.1级地震的1768个高质量数字加速度计。格雷罗网络是墨西哥城国家自治大学研究所和内华达大学雷诺分校的联合项目。主要支持由UNAM提供，它已将大多数设备从12位升级为19位数字记录器，并提供现场支持、数据回放和数据组织的主要部分。在美国，这些数据将提供对太平洋西北部因卡斯卡迪亚俯冲带预计将发生的类似地震而产生的地面运动的估计，也将提供受阿拉斯加俯冲带影响的地点的地面运动估计。

This action is to continue support for operation of the Guerrero network, together with analysis of the data collected.The Guerrero Accelerograph Network was installed in 1985 as a 30-station network of strong motion instruments along the coast of Mexico. The purpose of the network is to recover accelerograms from an expected magnitude 8 earthquake in the Guerrero seismic gap. While this major earthquake has not yet occurred, the network has obtained accelerograms from numerous small to moderate-sized earthquakes. In the 15 years through the end of 1998, the network recorded 1768 high-quality digital accelerograms from 738 earthquakes with magnitudes less than 3 to 8.1.The Guerrero network is operated as a joint project of the Instituto de Ingenieria at the Universidad Nacional Autonoma de Mexico (UNAM) in Mexico City, and the University of Nevada at Reno. Major support is provided by UNAM, which has upgraded most of the equipment from 12-bit to 19-bit digital recorders, as well as providing the major part of the field support, data playback, and data organization.Data from the expected break on the Guerrero gap will have international significance. In the United States, the data will provide estimates of ground motion in the Pacific Northwest due to a comparable earthquake expected on the Cascadia subduction zone; also for locations affected by the subduction zone in Alaska.
