Abstract:	摘要： A temporary seismic network consisting of 295 land stations was deployed in 2009 in Taiwan to monitor airgun sources during an onshore-offshore experiment in Taiwan. We exploit the continuously recorded dataset to detect and map seismicity in the seismically very active Taiwan. By combining recent automatic detection and phase picking techniques, we successfully generate an initial earthquake catalog of over 8400 events. The hypoDD algorithm is used to relocate and filter these events. This network recorded smaller events than the permanent regional network because of the many stations around the high mountain ranges and the generally high station density along 6 lines. The results based on the 2009 data generally reproduce the dominant seismicity features from many years of earthquake monitoring in Taiwan. In addition, we map hitherto unknown dipping zones under the Foothills and the Central Range that may correspond to seismogenic structures. •A temporary network of linear arrays was set up in Taiwan for 2 ½months to monitor offshore airgun shots.•The continuously recording stations acquired a large amount of earthquake data.•Using automatic detection and picking and hypoDD more than 4800 events are taken as well-located.•Main seismicity patterns under the island are identified in the results.•In addition, trends under the western Coastal Plain and the Central Range are recognized. 出版者： Amsterdam: Elsevier B.V 出版日期： 2016-12-05 出處： Tectonophysics, 2016-12, Vol.692, p.152-163 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2016 版權： Copyright Elsevier BV Dec 5, 2016 識別號： ISSN: 0040-1951 識別號： EISSN: 1879-3266 識別號： DOI: 10.1016/j.tecto.2016.04.025
