Figure 1 shows the location of the site within Kaohsiung City (the second most important city in Taiwan), together with the seismicity since 1900 (i.e., more than 55,000 events). It is worth noting that this earthquake catalog was used for the seismic hazard analyses, as it has been analyzed for quantifying earthquake potentials for Taiwan (Wang et al. 2011, 2012a, 2012b).
