记者18日从成都高新减灾研究所获悉，该所在中国科技部、中国地震局、四川省科技厅、四川省“百人计划”等支持下，建设了覆盖面积40万平方公里的地震预警系统，超过日本地震预警系统所覆盖的37.7万平方公里，成为世界最大地震预警系统。

Chengdu (CNS) -- The Chengdu Hi-Tech Disaster Mitigation Institute has built the world's largest earthquake warning system in west China, according to the director of the institute on Monday.

The system covers an area of 400,000 square kilometers, bigger than the 377,000 square kilometer warning system in Japan.

The network is made up of 1,213 monitoring instruments and warning centers in eight provinces including Gansu, Shaanxi, Sichuan and Yunnan.

The system was developed with both domestic and foreign technology, said Wang Tun, director of the institute.

Its reaction time once a quake occurs is an average of 7.0 seconds, while Japan's is an average of 9.0 seconds, he said.

The system integrates television, computers, mobile phones and microblogs for alerts, he added.
