Taiwan to boost quake warning systemNovember 15, 2009 in Earth / Earth Sciences
Taiwan plans to build its first undersea seismic station, designed to improve the island's early warning system and save valuable seconds when earthquakes strike, officials said.
The station, which is due to come into service in 2011, would help reduce the margin of error when monitoring undersea quakes and improve on the island's existing system of land-based seismic stations.
The new facility would provide a roughly 10 second warning ahead of earthquakes and a 10 minute alert ahead of the impact of a tsunami, according to Kuo Kai-wen, the head of Taiwan's Seismology Centre.
"The few seconds extra will give people precious time to seek shelter and flee coastal areas in the case of killer quakes," he told AFP.
NEC of Japan won the 423 million Taiwan dollar (13 million US) contract to build the station, which will be situated some 45 kilometres off the northeastern coast, an area frequently hit by earthquakes, he said.
The island, which lies near the junction of two tectonic plates, is regularly shaken by earthquakes. A 7.6-magnitude quake killed about 2,400 people in September 1999.
