摘要
本文针对我台微震仪记录到台湾澎湖岛西南海中的Lg波进行分析。笔者认为台湾海峡地壳有低速层的存在并影响S波的正常出现,这时利用Lg波震相,可以帮助我们定出比较可靠的震中距离。
The paper analyses the Lg wave recorded by microvibration detector of our station from the sea southwest of Taiwan Penghu Islands, The writer considers that there is Low - velosity layer in the crust of Taiwan of S Wave. Making use of Lg Wave vibration phase at this moment, it may help us decide relatively relible distance from earthquake center.
