記者18日從成都高新減災研究所獲悉，該所在中國科技部、中國地震局、四川省科技廳、四川省“百人計劃”等支持下，建設了覆蓋面積40萬平方公里的地震預警系統，超過日本地震預警系統所覆蓋的37.7萬平方公里，成為世界最大地震預警系統。

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.
