In this work, we quantify the effect of source uncertainties, other than earthquake magnitude and location, in rapid seismic intensity determinations in Taiwan using the strong-motion accelerograms recorded by stations of the Taiwan Strong-Motion Instrumentation Program (TSMIP) between 1991 and 2010. We find that rapid earthquake reporting assumes that a point source has an uncertainty of 0.5° in intensity and 7:2 cm/s 2 in peak ground acceleration (PGA). Therefore, these values can be regarded as the upper bound for precision in the Taiwan rapid reporting system (RRS).
