100 new earthquake early warning stations to be built in East Guangdong, Earthquake information would be released within 10 seconds

Earthquake early warning refers to communicating the news of the earthquake with people in the relevant affected areas after the earthquake but provides an alarm a few seconds to tens of seconds in advance to the time when the region will be affected which enable the local businesses and the public to approach early emergency response and thus reduce casualties and losses caused by disasters.

Currently the seismic network in Guangdong Province consists of a provincial network center, 72 seismic stations, two seismic arrays, 115 strong-motion earthquake arrays, 14 GPS units and more than 40 precursors. At present, the province’s earthquake monitoring capacity covers any earthquakes reaching Ms 1.5, the first to achieve automatic quick report within 10 minutes.

In response to the recently Sichuan Lushan Earthquake, Guangdong is now implementing the Pearl River Delta Earthquake Early Warning Station Network project. According to the design of the plan, the project will involve the construction of approximately 100 new earthquake early warning stations (mainly underground stations) in the eastern region of the province, with an average station spacing of 15 km. These new stations located in the eastern Guangdong will be connected to the Pearl River Delta and Hong Kong and Macao seismic network in forming an early warning station network. The new system is expected to provide quick earthquake report within 10 seconds.

80% of the project is expected to be completed within 2013, the network connection and integration would be completed in the first half of 2014, which would produce early warning information in 2015.
