     Micro-seismic monitoring involves the location of micro earthquakes and tomography of crust structures.Various location methods of micro-seismic monitoring are required to construct objective function,the essence of the location problem is seeking the minimum of the objective function.The global location method,such as neighborhood algorithm （NA） does not depend on the initial value of the model and will not converge to local minima,therefore of higher accuracy and reliability than the traditional linear approximation.Velocity structure around earthquake regions can been obtained from inversion of phase analysis and travel time picks of seismic data.Smaller-scale micro-seismic monitoring has been widely used in oil and gas field exploration,shale gas development.It has also been used in rock boost,coal and gas outburst related with the mine,water inrush forecast,and dam site,slope stability of water power station,natural landslide monitoring.
