- Abstract:
- In order to assess the monitoring capacity of the Yunnan Seismic Network,and analyze the characteristics of the spatial and temporal distribution of the Network's monitoring capacity in Yunnan,we select the earthquake catalogs,seismic phases,and station information during the period of 2009-2023,and use the probability-based magnitude of completeness(PMC)method to compute the average monitoring capacity of the Network,and the capacity at different depths.We obtain that MP value in some parts of central and western Yunnan reaches 1.5,and throughout Yunnan,the Network is capable of monitoring 2.5-magnitude earthquakes.The evolution of the Network's monitoring capacity over the past 15 years is assessed,and some stations' monitoring capacity has been declining,and after 20 new stations having been built in 2018,the monitoring range of 2.0-magnitude and 2.5-magnitude earthquakes of the Network in Yunnan has been expanded,but the Network's capacity of monitoring micro-earthquakes is not improved significantly.Perhaps the reason is that small earthquakes in Yunnan is very inactive since 2018.Finally,an outlook for the application of the PMC method for improving the monitoring capacity of the seismic network is put forward.
