| Abstract: | Selecting earthquakes occurred in different areas of Shandong Province and adjacent regions, rules of locating sub-array selection are studied based on analyzing the influence of station distributions on the accuracy of locating result. The difference of locating deviation, horizontal error, fitting residual with clearance angle, variation with near station and far station, and relation of locating deviation with horizontal error and fitting residual in the circumstances of two different types of station distribution were discussed, respectively. The results indicate that it is suitable to select 4 to 9 stations for earthquake locating in rapid report. It is relatively suitable to evaluate the quality of the locating result with horizontal error. |
