摘要:	The source location of the 16 September 1994 Taiwan Strait earthquake was relocated based on the beam-forming method using joint seismic observations from regional seismic networks in Taiwan and Fujian and the International Seismological Center Bulletin. The revised epicenter is located at latitude 22.37 degrees N (+/-0.03 degrees) and longitude 118.63 degrees E (+/-0.03 degrees). Results of this study showed that the location uncertainty has been significantly reduced using this approach. Decomposition tests of this study showed that the epicenters of Taiwan Strait events can be determined by the beamforming method using data from densely distributed seismic stations in Taiwan. However, source depths of Taiwan Strait events can not be determined unambiguously using the first P-arrivals only. Seismic waveform data should be carefully re-examined using this method to investigate earthquake source properties and seismicity of the Taiwan Strait region.
