Abstract:	摘要： The present study is proposed to investigate temporal variations of soil–gas composition in the vicinity of different fault zones in Taiwan. To carry out the investigations, variations of soil–gases compositions were measured at continuous earthquake monitoring stations along Hsincheng and Hsinhua faults in Hsinchu and Tainan areas, respectively. Before selecting a monitoring site, the occurrence of deeper gas emanation was investigated by the soil–gas surveys and followed by continuous monitoring of some selected sites with respect to tectonic activity to check the sensitivity of the sites. Based on the results of long term geochemical monitoring at the established monitoring stations we can divide the studied area in two different tectonic zones. We proposed tectonic based model for earthquake forecasting in Taiwan and tested it for some big earthquakes occurred during observation period i.e. 2009–2010. Based on the anomalous signatures from particular monitoring stations we are in a state to identify the area for impending earthquakes of magnitude ≥5 and we have tested it for some earthquakes which rocked the country during that period. It can be concluded from above results that the stress/strain transmission for a particular earthquake is hindered by different tectonic settings of the region under study. ► Variations of soil–gases composition is studied at two different faults of Taiwan. ► Tectonic based model for earthquake forecasting in Taiwan was proposed and tested. ► Selection criteria to identify threshold earthquakes have been defined. ► Stress/strain transmission for earthquake may be hindered by tectonic settings. 出版者： Kidlington: Elsevier Ltd 出版日期： 2013-03-01 出處： Radiation Measurements, 2013-03, Vol.50, p.154-159 版權： 2012 Elsevier Ltd 版權： 2014 INIST-CNRS 識別號： ISSN: 1350-4487 識別號： EISSN: 1879-0925 識別號： DOI: 10.1016/j.radmeas.2012.11.007
