Unusual earthquake sequence analysis and its tectonic implications

This topic aims at investigating some out-of-the-ordinary earthquakes against the background tectonics. For example, in the case of a large inland earthquake, 4 March 2010 MW 6.3 Jiasian, Taiwan earthquake, occurring in a seismic gap, we integrated the strong motion data to better relocate the earthquake sequence, determined the focal mechanisms, and discussed their implications to tectonics and hazard mitigation for southern Taiwan (Huang et al., 2011). Two years later, the ML 6.4 Wutai, Taiwan earthquake occurred nearby and a bit deeper. Using a P-wave polarity fitting method, we also reexamined its source parameters for tectonic discussion (Chen et al., 2013).
