We implemented an automatic procedure to update in near‐real time (daily to hourly) a homogeneous catalog of Italian instrumental seismicity to be used for forecasting experiments and other statistical analyses. The magnitudes of all events are homogeneously revalued to be consistent with Mw standard estimates made by the Global Centroid Moment Tensor project. For the time interval from 1960 to 15 April 2005, catalogs and online resources available for the Italian area were merged and all magnitudes were homogenized to Mw according to empirical relationships computed using the chi‐square regression method, which properly consider the uncertainties of both variables. From 16 April 2005 to the present, an automatic procedure periodically downloads the data of the online bulletin of the Istituto Nazionale di Geofisica e Vulcanologia and of online moment tensor catalogs from respective websites, merges the different sources, and applies traditional magnitude conversions to Mw⁠. The final catalog is provided on a website for public dissemination.

1960年至今意大利的均质仪器地震目录(HORUS)

我们实施了一项自动程序,以近实时(每天至每小时)更新意大利仪器地震活动性的同类目录,以用于预测实验和其他统计分析。所有事件的大小均等地重估,以与Global Centroid Moment Tensor项目做出的Mw标准估计值一致。在1960年至2005年4月15日的时间间隔内,将意大利地区可用的目录和在线资源合并,并根据使用卡方回归方法计算的经验关系将所有量级均化为Mw,并适当考虑了两个变量的不确定性。从2005年4月16日至今,自动程序会定期从各自的网站下载Istituto Nazionale di Geofisica e Vulcanologia的在线公告数据和在线弯矩张量目录的数据,合并不同的来源,并将传统的幅度转换应用于Mw?。最终目录在网站上提供,以供公众传播。
