中文摘要 我們收集了台灣區域的1-Hz GNSS測站與寬頻地震測站在2011年Mw 9.0 Tohoku地震與2012年Mw 8.6 Sumatra地震的資料,進行遠震之表面波分析,在GNSS解算上使用GIPSY 6.3軟體進行每秒的精密單點定位(Precise Point Position),並使用帶通濾波(band-pass filter, 0.008-0.08Hz)後GNSS與寬頻地震站之波形相關係數在0.86到0.92之間,而我們使用台灣與琉球區域的GNSS測站在沖繩海槽區域進行表面波的速度構造反演,其結果中發現在沖繩海槽區域深度約30公里以上有明顯的低速帶(low-velocity zone),此區域可以指示在沖繩海槽為弧後的擴張區域與熱對流上升之主要位置。除此之外,在觀測2011 Mw 9.0 Tohoku地震的Love wave表現中,在台灣西半部前陸盆地發現有明顯的後達波(later phase),此在頻率域分析約為15-25秒周期之訊號,此訊號主要是受到淺部地殼(約20公里以上之深度)的影響,在單站頻散分析中,後達波之訊號主要在台灣逆衝前緣以西的區域產生,且後達波的振幅可以反映出台灣西部前陸盆地之沉積物厚度變化,而經由後達波在BBFK(broadband frequency-wavenumber)的波向來源方位分析,其波前之傳遞方向與後方位角之夾角,由台灣西北往西南部有變小的程現,其原因可能為表面波由東至西經過台灣逆衝前緣,表面波由低速區(中央山脈)至高速區(西部平原)折射而產生,而傳遞路徑也受到台灣西半部前陸盆地的地體構造影響而延著其構造變化。
英文摘要 Surface waves generated by the 2011 Mw 9.0 Tohoku, Japan earthquake and the 2012 Mw 8.6 Sumatra earthquake were recorded by broadband seismic stations and 1-Hz GNSS stations in the Taiwan and Ryukyu region. All GNSS stations were processed by GIPSY 6.3 with Precise Point Positioning (PPP) method to estimate the absolute epoch-by-epoch positions. Both time series of GNSS and broadband seismic stations are highly consistent with correlation coefficients between 0.86 and 0.92. We combined surface wave data recorded by GNSS and broadband seismic stations to measure Love wave dispersion curves by the two-station technique. The average two-dimensional shear wave velocity model in the Okinawa Trough region is estimated and the Okinawa Trough is indicated by a low-velocity zone at depths above 30 km, which can be related to the presence of back-arc extension and the region of melt generation. In addition, Love wave later phases with periods of 15-25 s are observed in the western part of Taiwan. Analyzing the depth of western foreland flexure with later phase amplitude and using broadband frequency-wavenumber (BBFK) method to detect the source of later phase, we found that the later phase amplitudes evidently reflect the depth of foreland flexure and the propagation path of later phase is controlled by the along-strike geometry of western foreland structure.
