Simulated annealing for earthquake location

Earthquake location is one of the most basic tasks of seismology research such as earthquake monitoring and earthquake prediction. Identification of earthquake location with high efficiency and accuracy is of great significance to the development of works of earthquake prevention and mitigation. In this paper, we invert the earthquake location by simulated annealing algorithm. And then, we change the initial temperature, temperature threshold, cooling-rate, convergence threshold, and disturbance mode respectively to find their influence on the result of simulated annealing algorithm. At last, we summarize and analyze the advantages and disadvantages of simulated annealing algorithm.
