摘要
To determine the studying region of China Testing Center of Collaboratory for the Study of Earthquake Predictability (CSEP), the authors 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, the authors 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.
