Some Developments and New Insights for Microseismic/Acoustic Emission Source Localization

Multistep localization method (MLM) for locating sources in the heterogeneous and complex media. Through the continuous narrowing and optimization for P-wave velocity interval, the optimal localization results with higher accuracy can be solved successfully. Based on the field test, as well as the comparison between MLM, TD, and TLM, it can be proved and concluded that MLM is superior to other two methods and has higher locating accuracy and computation efficiency (from [81]).
