A coherence-based earthquake detection technique was applied to continuous (1 year) waveform data recorded along the Irpinia fault system (Southern Italy). The earthquake detection was performed using coherent P- and S-wave arrivals recorded by the dense seismic network operating in Irpinia and assuming a local velocity model. We applied a strategy to simultaneously detect and locate earthquakes and to discriminate among true and false detections using an automated and fast procedure, able to process 1 year of data in ~ 1.75 days. The final catalogue of automatically retrieved earthquakes shows a performance improvement with respect to the standard monitoring practices, with an increase in the number of detected small events of about a factor three with respect to the automatic Earth-worm Binder implemented in ISNet and decreases in completeness magnitude of almost half unit magnitude.

基于相干性的方法在地震检测和微震监测中的应用(意大利南部Irpinia断层系统)

将基于相干性的地震检测技术应用于沿Irpinia断层系统(意大利南部)记录的连续(1年)波形数据。地震检测是使用由在Irpinia中运行的密集地震网络记录的相干P波和S波到达进行的,并采用局部速度模型。我们采用了一种策略,可以同时检测和定位地震,并使用自动,快速的程序区分真假检测,能够在1.75天内处理1年的数据。自动检索的地震的最终目录显示,与标准的监测方法相比,性能有所提高,
