We have developed a simple method of array analysis, enabling to find out apparent radiation centers of teleseismic waves. Applying this method to short‐period P waveforms from the 1989 Macquarie Ridge earthquake recorded at 7 stations of the Pre‐POSEIDON network in Japan, we obtained a pattern of apparent radiation center migration that is more compatible with a bilaterally propagating source model than with a unilateral one.
