| Abstract: | To determine the studying region of China Testing Center of Collaboratory for the Study of Earthquake Predictability(CSEP),we used the entire-magnitude-range(EMR) method to study the spatial distribution of minimum magnitude of completeness(Mc) in the North-South Seismic Belt from Oct.1,2008 to May 31,2011.Also bootstrap testing are performed to estimate the uncertainty of Mc,i.e.δMc.The results show that Mc(EMR)=1.6±0.03 for the whole region.From the spatial distributions of Mc,we find that Mc is in the range of ML1.3~2.0 for most regions.Specifically,the spatial distributions of Mc are consistent with the distributions of stations with high monitor level in the south segment and low monitor level in the north segment.Location with less than three stations has a great influence on Mc.Moreover,the uncertainties of minimum magnitude of completeness(δMc) range from 0.07 to 0.22.The spatial distribution of δMc is consistent with the seismic rate.Shorter time interval may cause larger δMc. |
