Seismometric network

The seismometric network consists of eight surveying stations equipped with digital seismic acquisitors to which two three-dimensional sensors are connected, one seismometric and one accelerometric. The high dynamics of the acquisitors, together with the inherent characteristics of the sensors, allow for high quality data recording, from the weakest local events up to strong global earthquakes.

The seismometric type sensors are either short period, with their own frequency of 1 or 5 seconds, or wide band, with their own frequency of 40 seconds. For accelerometric sensors, please refer to the dedicated section. Data transmission takes place in real time, 24 hours a day, and each acquirer is equipped with a GPS receiver that provides synchronisation of the internal clock with absolute time (UTM), an indispensable condition for subsequent seismological processing, both automatic and manual.

The seismometric network is identified at an international level by the abbreviation ST and the code DOI:10.7914/SN/ST(Digital Object Identifier) registered with the FDSN(International Federation of Digital Seismograph Networks), while the abbreviations of the various stations are registered with the ISC(International Seismological Centre), which manages the international register of seismic stations worldwide. The seismometric stations in Trentino are integrated with those in Alto Adige, Veneto, Friuli Venezia Giulia, Slovenia, Austria and Switzerland, contributing to an optimal instrumental coverage of the central-eastern Alpine arc.

At present, the remote stations transmit a data stream in digital format in real time via WiFi radio equipment (5.4 GHz), which provides a connection to the nearest access point to the new TETRA provincial radio network or fibre optic node. The data then flows to the acquisition centre at the Multifunctional Centre in Spini di Gardolo, where it is decoded and stored on computer media. Through a dedicated connection, the signals recorded by the stations are also shared with other national and foreign seismological centres.
