過去幾年在明多洛哥島西北五個寬頻測站的設置與資料蒐集對區域地體構造的了解有所貢獻。由地震分布所決定的隱沒板塊的傾角往東南方向增加，從碰撞起始到碰撞結束的區域方向，主要以張力軸平行傾角的應力作用。我們以簡化的明多洛島與馬尼拉海溝南段的地體構造模擬弧陸碰撞隨著時間的演化。我們加上明多洛島測站的資料重新定位2017規模5.9菲律賓八打雁(Bantangas)地震的結果得到八打雁灣內密集分布的地震序列，顯示巴拉揚灣無法累積地震應力的特徵是受到Macalod火山走廊的地熱影響。本計畫中，我們應用一個新穎的方法，叫做指紋相似性門檻法(FAST)來偵測明多洛島測站連續資料的地震事件。藉由把波形建立成可分辨特徵的指紋符號，以搜尋相似性，此方法是一自動搜尋的方法，無須模板地震的波形特徵，具有震測敏感度、廣泛應用性、計算效率高的優點。我們預期應用FAST方法在明多洛島的測站資料可以得到更全面地震活動的監測。 ;Deployments and data collections of the five broadband stations in NW Mindoro over the past few years have contributed to the understanding of regional tectonics. Dip angles of subducting slabs determined by hypocentral distributions increase southeasterly from regions of ongoing to cessation of convergence with down-dip extension dominant stress patterns. The temporal development of arc-continent collision was dynamically modelled based on a simplified representation of Mindoro Island and the southern Manila Trench. Relocations of the 2017 Mw5.9 Batangas, Philippines earthquake using additional Mindoro stations result a compact series within the Batangas Bay, suggesting aseismic nature of the Balayan Bay subjecting to the geothermal impact of the Macolod Corridor. In this proposal, we employ a novel method – Fingerprints And Similarity Thresholding (FAST) - to identify seismic events in continuous data of Mindoro stations. By creating “fingerprints” of waveforms with discriminative features for search of similarity, FAST is a blind detection method without prior knowledge of waveform signatures that scores high on detection sensitivity, general applicability, and computational efficiency. We expect the resulting applications of FAST on Mindoro stations will help on a comprehensive monitoring of regional seismic activity.
