全球地震台网记录苏门答腊-安达曼地震的地幔波
Mantle surface wave of the great Sumatra-Andaman earthquake recorded by the Global Seismograph Network
【摘要】 介绍印度尼西亚苏门答腊-安达曼MS8.7地震在全球地震台网(GSN)及所含“新一代中国数字地震台网”(NCDSN)记录的地幔面波。主要讨论本次大地震地幔瑞利波Ri,j(环球瑞利面波)无频散的3种可能原因,同时提出地幔妹泽波Mi,j的问题。
【Abstract】 The mantle surface wave of the Great Sumatra-Andaman M_S 8.7 earthquake recorded by GSN and NCDSN had been introduced. We have discussed 3 possible reasons why the mantle Rayleigh wave R_ i,j of the earthquake has no dispersion and put forward the question about the mantle Seazawa wave M_ i,j.
