Hong Kong Short-period Seismograph Network

In recent years, there is considerable interest in local and regional seismicity.  The occurrences of disastrous earthquakes in China, such as Tangshan earthquake in 1976, heighten the awareness of the need to take seismic risk into account in engineering studies.

In order to monitor in greater details the location and magnitude of earthquakes near Hong Kong, a network of three short-period seismographs was installed in 1979.  It was upgraded to an advanced digital network with seven stations called the Hong Kong Short-period Seismograph Network in 1997.  These stations are located at Cape D'Aguilar, Cheung Chau, Keung Shan, Lead Mine Pass, Luk Keng, Tsim Bei Tsui and Yuen Ng Fan.  Data are transmitted round-the-clock to the Observatory headquarters where the locations and magnitudes of earthquake detected are computed.
