has a high seismic risk related to the earthquake events along active fault such as sianolk, ankgkola. and caused many fatalities
We examine several approaches to estimate the potential (that is, the probability per unit area, magnitude and time) for magnitude 5. 4 and larger earthquakes in China. We tested the Global Seismic Hazard Assessment Project (GSHAP) model, and constructed our own models based on past seismicity and fault activity, respectively. We constructed a special earthquake catalog that combines previous catalogs covering different times. We estimated moment magnitudes for some events using regression relationships that we derived. We used the special catalog for constructing our smoothed seismicity model and testing it retrospectively. We estimated the completeness threshold, the b-value, and the upper magnitude limit using maximum likelihood. The smoothed seismicity method assumes that the rate density is proportional to the magnitude of past earthquakes and approximately on
