摘要
山东数字地震台网自主研制了一套地震自动定位软件系统，2008年5月在山东地震台网中心试运行，运行稳定。本文对该系统运行期间自动定位结果进行了统计与分析，结果表明，山东数字地震台网自动定位系统对于网内天然地震定位结果可靠，震中平均偏差4．09km，震级偏差±0．08，平均速报用时63s。
We developed a automatic positioning system for earthquakes. It has been tested running in Seismic Network of Shandong Province since May, 2008. In this paper, we analyzed statistically the process results of earthquakes occurred in tested running. The results show that the automatic treatment result for natural earthquake within the network is reliable. The average deviation of epicenter is 4.09 km, magnitude deviation is ± 0. 08. The average time for earthquake speed report is 63 s.
