Magnitude 6 earthquake strikes Sichuan, kills 13
As of 8 am Tuesday, a total of eight buried people were retrieved from the debris, and over 600 people were relocated by the armed police forces. They have also finished transporting 12 tonnes of supplies and put up over 120 tents.
The quake caused a major highway connecting Yibin and Xuyong county of Sichuan's Luzhou city to be closed. Some sections of other roads were also blocked or closed.
In the provincial capital Chengdu, an early warning system alarmed the public through multiple broadcasting systems about one minute before the earthquake struck. The same system alerted residents in Yibin 10 seconds before the quake hit.
The early warning system uses the theory that radio waves travel faster than seismic waves.
Earthquake research has found that being aware of an earthquake three seconds beforehand can save 14 percent of casualties, 10 seconds can save 39 percent of casualties and 20 seconds can save 63 percent of casualties.
