台灣車籠埔深鑽(TCDP)在斷層帶上下設置7-level地震儀,深度為地下850~1300公尺。此井下地震儀紀錄可紀錄極微小地震,且低雜訊,將可有效的分析,小地震至大地震的地震波相特性。TCDP-A井中安裝三分量七層井下地震儀陣列(圖1.1),間距為50到60公尺,跨越車籠埔斷層主要破裂帶1111公尺,本計畫在計劃中,如計畫時程規劃,以下列方向進行,達到研究目的: 1.由井下地震儀分析淺層及斷層帶衰減特性。 2.蒐集井下地震儀地震資料分析地震尺度的震源參數關係。 3.持續分析小地震及大地震起始波形的特性。 在此三年期的計畫中將陸續由以上的計畫目標進行觀測及研究,以目前及未來持續紀錄的地震分析其特性以助於了解地震斷層的特性。Taiwan Chelungpu-fault Borehole Seimsomters (TCDPBHS) deployed at the depth spanned from 950m to 1300m, which crossing the fault at 1111m had recorded very nice waveform for micro-eartqhuakes and cluster events near and close to the Chelungpu fault. Our project will carry on for the following research targets, 1.Investigation of the attenuation structure of fault zoned 2.Earthquake scaling law for small to large earthquake 3.Investigation of the possible initial phases of small to large events The results from this study will understand the earthquake physics of small to large earthquake and the fault zone structure for further understand on prediction of the faulting behavior of large earthquake. 研究期間:9901 ~ 9912
