| Abstract: | Statistic calculation is made with the help of image analysis and event query of Mapinfo software to figure out current b value and average annual incidence of earthquakes in Fen wei seismotectonic zone The analysis is made for the result The conclusion is that current b value and average annual incidence of earthquakes in Fen wei seismotectonic zone is marginally different from ones obtained 10 years ago, due to rare strong earthquake occurrence in the zone |
