A tsunami early warning center built by China and covering nine countries went into full operation on Tuesday to mark the fourth World Tsunami Awareness Day.
The South China Sea Tsunami Advisory Center is hosted by China's National Marine Environmental Forecasting Center and was authorized by UNESCO's Intergovernmental Oceanographic Commission. It began trial operations in January last year.
With access to real-time data from over 600 earthquake monitoring stations, including 530 in foreign countries, the tsunami advisory center is able to figure out the basic parameters of an earthquake within three to five minutes no matter where it occurs.
In addition to 106 domestic stations for water level monitoring, the tsunami advisory center receives data from over 800 such stations across the world.
