Spatiotemporal seismicity pattern of the Taiwan orogen

Abstract

We investigate the temporal and spatial seismicity patterns prior to eight M>6 events nucleating in different regions of Taiwan through a region-time-length algorithm and an analysis of a self-organizing spinodal model. Our results show that the spatiotemporal seismicity variations during the preparation process of impending earthquakes display distinctive patterns corresponding to tectonic settings. Q-type events occur in southern Taiwan and experience a seismic quiescence stage prior to the mainshock. A seismicity decrease of 2.5
