在破坏性地震发生后迅速部署密集的临时地震台网，是提高地震监测和余震序列研究质量的必要措施。用密集的地震台网记录地震波可以大大提高地震的探测和震源参数的估计。自1990年以来，国家地球物理和火山学研究所（意大利语：Istituto Nazionale di Geofisica e Vulcanologia， INGV）管理着一个便携式地震台网结构：一个用于部署密集地震台网进行科学实验和监测破坏性地震发生后余震的仪器池。今天，这个数据库包括大约100个地震台站，如果有必要，可以集成到INGV的实时地震监测系统中。实时数据有助于监测震中地区的地震活动性，记录的地震图的离线分析允许断层系统的几何和运动学成像。我们介绍了INGV便携式地震台网，它的历史和目前与其他意大利和国际研究所的协调项目。此外，我们还介绍了过去五年的组织活动和紧急行动，特别侧重于“Emilia 2012”和“Pollino 2011-2014”地震危机。
The rapid deployment of a dense temporary network of seismic stations, soon after the occurrence of a damaging earthquake, is an essential action to improve the seismic monitoring and the quality of the studies on the aftershock sequence. Having seismic waves recorded with a dense seismic network can greatly improve the detection of earthquakes and the estimation of hypocenter parameters. Since 1990 the National Institute of Geophysics and Volcanology (Italian: Istituto Nazionale di Geofisica e Vulcanologia, INGV) manages a Portable Seismic Network structure: an instrumental pool to deploy dense seismic networks for scientific experiments and to monitor aftershocks after the occurrence of damaging earthquakes. Today, this pool, includes about 100 seismic stations which, if necessary, can be integrated in the real time seismic surveillance system of INGV. The real time data contribute to the monitoring of the seismicity in the epicentral area, the off line analysis of the recorded seismograms allows the imaging of the fault system geometry and kinematics. We present the INGV Portable Seismic Network, its history and the current coordination projects with other Italian and international Institutes. Moreover we describe its organization activities and its emergency operations in the last five years with special focus on the “Emilia 2012” and the “Pollino 2011–2014” seismic crises.
