摘要
对于2004年12月26日印度洋大地震,成都地震遥测台网有宽频带数字地震记录波形没有出格,测定的面波震级为9 0。这对于通常人们认为面波震级超过8 6可能出现饱和是一个值得注意和研究的现象。
The Sumatra earthquake with Ms8.7 occurred on 26 December 2004. The Digital Seismic Network of Chengdu with the wide frequency band determines this earthquake with the surface wave magnitude 9.0. It is a noticed problem that if the surface wave magnitude of an earthquake exceeds the M8.7 class, the figure of wave will be limited by the recording system and the problem of magnitude saturation appears.
