摘要
Abstract
Scientific evaluation of Mc is an important foundation for conducting seismic activity level,earthquake occurrence rate,and seismic hazard analysis.This paper uses the seismic catalog of the surrounding area of the Ordos block and various statistical seismological methods based on the Gutenberg Richter(G-R)formula to find the optimal method for determining the minimum complete magnitude of the region.The overall completeness magnitude of the study area is Mc=1.2,with a b-value of 0.6+/-0.00.The complete magnitude around Ordos changes obviously with time,and on the whole,the complete magnitude has decreased year by year since 2008,indicating that the seismic network has been encrypted year by year and the earthquake monitoring capability has been strengthened.关键词
