摘　　要：近年来为提高防震减灾的智能化水平,日本气象厅不断完善地震观测系统的功能和海啸的智能化预测水平,并且努力提升地震和海啸预警服务能力。2022年12月开始发布北海道及三陆地区后续地震预警信息,2023年2月开始发布长周期地震动等级的地震预警信息。本文旨在为中国的地震预警系统的研究与建设提供参考和借鉴。In recent years,in order to improve the intelligent level of earthquake prevention and disaster reduction,the Japan Meteorological Agency has continuously improved the functions of the earthquake phenomena observation system(EPOS)and the intelligent prediction level of tsunami,and has made efforts to improve the earthquake and tsunami early warning service capabilities.In December 2022,it began to release follow-up earthquake early warning information in Hokkaido and Sanriku regions,and in February 2023,it began to release earthquake early warning information of long-term ground motion levels.This article aims to provide reference for the research and construction of earthquake early warning systems in China.
