　　After experiencing heavy casualties(伤亡)and damage in powerful earthquakes since 2008, China is developing a way to give at least a few extra seconds' warning for those near quake epicenters(震中)．

　　The system, called the National Earthquake Early Warning System, which will cost about 2 billion yuan, is expected to be built before 2017. The system mainly includes the construction of more than 5,000 quake­monitoring stations across the country.

　　The system works by detecting earthquake­related shakings in the form of P­waves. P­waves move rapidly but are harmless, and they arrive before the more powerful and destructive S­waves. S­waves travel more slowly. So detecting P­waves with the system can provide a few precious seconds for people to escape before the more powerful S­waves arrive.
