  • 图  1  Allen和Stogaitis(2022)总结的全球地震动和预警系统分布图. 圆圈代表6.5级及以上强震可能的震动区域. 粉色区域表示震动可以被感受到,红色区域表示震动可能造成破坏. 地震预警系统的地理分布用醒目的蓝色和绿色表示,绿色区域表示全部采用安卓地震警报系统. 日本、墨西哥、韩国和中国台湾使用永久地震站网. 美国西部的预警系统ShakeAlert,最初通过无线应急警报系统、MyShake和其他应用发布预警信息,现在也开始使用安卓地震警报系统

    Figure  1.  Allen and Stogaitis (2022) summarized the global distribution of earthquake shaking and early warning systems. Each circle shows the approximate shaking regions for magnitude 6.5 and larger earthquakes. The pink regions are where shaking is felt, and the red regions are where shaking causes damage. The current geographic distribution of EEW are highlighted in blue and green, with green areas entirely depending on Android Earthquake Alerts. Japan, Mexico, South Korea, and Taiwan, China have systems that use permanent seismic networks. The western US states have ShakeAlert, which initially sent alerts using wireless emergency alerts, MyShake, and other apps, but they now also have alerts delivered through Android Earthquake Alerts

    图  2  国家烈度速报与预警工程项目台站分布图. 蓝色三角形为基准站,站点配置了速度计和加速度计;红色三角形为基本站,站点配置加速度计;黄色圆点为一般站,站点配置简易烈度计
