    Abstract: 火山群可能在兩萬年內曾經活動過,但由於缺少近代歷史活動,因而大屯火山群被認為是死火山。本計畫中,我們將採用綜合性方法來研究大屯火山群,以瞭解其地震活動機制、變形與氣體釋放形式。本計畫將透過以下方法:(a)分析地震資料解析地震活動時域及空間域分佈的特性;(b)分析火山噴氣孔採得的氣體樣本,以觀察其是否存在異常成分及其週期性;(c)收集並分析大屯火山群GPS 資料,觀察其是否有前震變形;(d)收集並分析大屯火山群重力資料,以觀察其是否有因岩漿流動產生重力場變化的可能性。最後,將整合各組之觀測資料,評估其活動異常之週期,並用以建構未來大屯火山群之監測計畫。 ; The Tatun Volcano Group (TVG) is located at the northern tip of Taiwan, near the capital Taipei and close to important industrial/financial sites. Because of lack of any activity in historical times it has been classified as an extinct volcano, even though more recent studies suggest that TVG might have been active during the last 20 ka. In this proposal we aim at studying TVG in a multi-disciplinary manner in an effort to understand the mechanism of its seismicity, deformation and degassing patterns. We plan to achieve that by employing the following approaches: (a) analysis of seismological data in order to resolve time and space characteristics of seismicity; (b) geochemical analysis of gas samples from fumaroles in the TVG area, in order to find periods of possible anomalous gas compositions; (c) collection and analysis of GPS data in order to highlight any aseismic deformation taking place at TVG; and (d) collection and analysis of gravity measurements in order to infer possible changes in the gravity field around TVG due to the movement of magmatic fluids. Finally, all these datasets will be jointly evaluated for the purpose of assessing time periods of anomalous measurements and for establishing future volcano monitoring programs for TVG. 表 ; 研究期間 9808 ~ 9907
