摘　　要：在地震自动处理系统(JOPENS)的基础上,通过融合地震预警定位算法和震级快速计算方法,开发了一套地震超快速报系统。系统能够在地震发生后几秒至几十秒内自动确定地震的三要素。系统从2013年3月部署在广东省地震速报备份中心进行试运行。通过分析系统试运行至2014年7月间的自动定位结果后发现,超快速报系统把地震自动速报的用时从分钟级提高到了秒级,且定位精度并未降低。另对系统的漏报和误报情况进行了进一步的分析。On the basis of the seismic automatic processing system （JOPENS）, a set of earthquake very fast report system was developed by fusion of the earthquake early warning location algorithm and the fast magnitude calculating method. The system can automatically determine the three parameter of earthquake in a few seconds to tens of seconds after the occurrence of earthquake. The system was deployed in the backup center of Guangdong province earthquake quick report since March 2013. Through analysis of the automatic location results from trying to run to July 2014, the author found that the report time of the very fast report system was improved for the minute level to the second level. However, the location accuracy was not reduced. Besides, the paper did further analysis of the reasons of the missing and false report.
