  "abstract": "地震预警与地震速报要求尽早获得震级和震中位置等参数。针对台网边缘、台站稀疏及网外地震在多台关联形成前信息不足的问题，本文基于谛听（DiTing）地震波大模型构建单台事件信息快速判定与远震预警原型，集成3P波震相识别、连续目录震级估计、震中距估计、质量受控的反方位角辅助判断、多台递进定位及MQTT信息发布。本文首先使用2 009条近场P波记录考察目录震级估计，再以3个M7以上事件的6条区域至远场记录观察震级随输入窗口的演化，并使用4个网外事件的15条记录进行案例测试。全部15条波形记录处理结果显示，单台目录震级估计的平均绝对误差为0.234 级，绝对误差中位数为0.233 级，震中距绝对误差中位数为8.86 km，反方位角绝对误差中位数为163.26°。原型在所测试的远距离单台记录上完成了P波识别和目录震级估计；单台阶段根据预测震中距和反方位角计算初始震中位置，并作为单台首报位置发布；随后随着更多台站的加入，利用多台震中距约束递进更新震中位置。单台首报位置仍受反方位角误差影响，其精度需结合后续多台结果检验。2026年4月20日日本东部海域M7.4地震的实时数据处理展示了原型从波形接收到消息发布的完整链路。结果验证了该原型处理链路在所测试事件上的可运行性，并显示了利用远距离单台P波进行大震快速信息判定的潜力。现有结果属于典型事件案例验证，尚不能外推为不同地区、震级、台站和连续实时环境下的普适性能。",
