摘要
对全国自动地震速报系统进行简要介绍。根据《自动地震速报技术管理规定》,全国自动地震速报系统由5个区域自动地震速报分中心(辽宁、河北、福建、陕西及云南)和国家地震速报备份中心(广东省地震局)组成。通过"十五"国家测震台网的建设,利用全国1 000多个地震台站和200多个境外地震台站,现阶段自动地震速报能力达到国内地区1 min左右、周边地区2 5 min、国外其他地区3—30 min的水平。
A brief introduction about China＇s auto earthquake information system is given in this article. According to the auto earthquake information technology management regulations, Chinats auto earthquake information system consists of five regional auto earthquake centers （Liaoning, Hebei, Fujian, Shaanxi and Yunnan） and the national earthquake backup center （Earthquake Administration of Guangdong Province）. By ＂the tenth five-year plan＂ construction of national network, with more than 1 000 countrywide stations and more than 200 foreign stations, the capability of auto earthquake information can reach level of 1 minute for the domestic area, 2--5 minutes for the surrounding area, and 3--30 minutes for other regions.
