On 6 February 2016(UTC 19:57), the Meinong earthquake with Richter magnitude (ML) 6.6 struck southern Taiwan and caused hundreds of damaged buildings and resulted in 117 casualties. To realize which ground motion parameter is the most representative index corresponding to the disaster (building damage) of the Meinong earthquake, we investigated the relationship between the damaged buildings and the ground motion in the forms of peak ground acceleration (PGA), peak ground velocity (PGV), pseudo-spectral acceleration (SA) at 0.3 sec (SA0.3), 1.0 sec (SA1.0), and shaking duration. The PGV and the SA1.0 present better correlation with consequent damage. And, thus, the Intensity converted from PGV show better correlation to the damage than from PGA. To clarify the seismic source contributing to the hazard by the Meinong earthquake, we disaggregated the TEM PSHA2015 hazard contribution to the damage region of Meinong eartqhuake (Southern Taiwan) from different seismic source typologies. The hazard contributed by the Meinong earthquake are 16%, 26% and 23% for PGA, SA0.3 and SA1.0, respectively; to the predicted seismic hazard of area source are 38%, 61% and 75% for PGA, SA0.3 and SA1.0, respectively, for the PSHA with return period of 475 years. The result indicates that the 2016 Meinong earthquake did diminish partially the seismic hazard potential in southern Taiwan. However, more than about 80% of the seismic hazard potential, especially the fault sources, were not yet released. These values suggest that the seismic hazard potential in the southern Taiwan remains high regardless the occurrence of the 2016 Meinong earthquake.
