NEC has delivered a submarine cable seismic and tsunami observation system to Taiwan's Central Weather Bureau (CWB) under the Ministry of Transportation and Communications. The new system is mainly intended for observation of earthquakes and tsunami in the area ranging from the offshore coast of Yilan in eastern Taiwan to Fangshan in Pingtung County. 

The submarine cable measures 620 kilometers and reaches a depth of 5,800 meters. All products, including optical submarine cables, submarine observation units, and optical submarine repeaters, which constitute the system, were manufactured and assembled at NEC factories in Japan.

According to the CWB, when an earthquake occurs in the eastern sea area of Taiwan this new system can provide an emergency warning more than 10 seconds before the actual tremor is felt on land. Moreover, a warning can be issued 20 to 30 minutes before a tsunami reaches the coastal area. As a result, this system will contribute to the enhancement of disaster prevention and mitigation capabilities. For example, public transportation systems, including MRTs (Mass Rapid Transit) and HSRs (High Speed Rail) can quickly decelerate in the event of an earthquake.

Atsushi Kuwahara, General Manager, Submarine Network Division, NEC Corporation, said, "It is a great honor that the NEC Group can use its many years of experience in optical submarine cable communication technology and submarine observation technology to help prevent disasters and ensure safety for the residents and government of Taiwan. Going forward, we will continue to provide technology and solutions that contribute to the well-being of our communities."
