This research uses the maximum likelihood method which is a statistical method as a mitigation effort in determining the value of earthquake parameter (ɑ-b value), destructive earthquake repetition, and potentially devastating earthquake area. Data obtained to analyze earthquake-earthquake index distribution for this region is from earthquake catalog, USGS data and BMKG Kendari City Geophysical Station period 2007 - 2017. The result of data processing of magnitude conversion from body magnitude (Mb) to surface magnitude (Ms) using the maximum likelihood method indicates that the highest A values are in region I which means that this region has high seismic activity whereas the lowest b value is in region I which means large magnitude earthquake is more likely than other region because b value decreases before earthquake with magnitude big. The highest seismicity index with magnitude (M> 4 is located in region II which means the average number of earthquake events occurring with magnitude (M> 4) within one year in this region is quite high while the longest quake repeated period that is there on region one.
