THE INGV NATIONAL SEISMIC NETWORK IN 2013 :

• A dense and high-quality integrated network, a powerful tool for both early warning and investigating earthquake processes and Earth structure in the Mediterranean basin.• 470 3- (or 6-) component stations.• 180 accelerometric stations. • Data Integration: 370 INGV stations + 100 stations from local, regional, and abroad networks.• VBB, BB, or enlarged band sensors.• High dynamic range dataloggers (GAIA, Nanometrics, Quanterra).• Fully digital IP transmission (satellite, wired intranet/internet, Wi-Fi, UMTS).• Redundancy on servers and data centres to reduce data black-out risks.• New procedures for data acquisition, management and analysis (mostly developed at INGV).• Faster and more accurate hypo-central locations and magnitude.• Integration of continuous GPS stations.

Is composed by more than 100 seismic stations equipped with both accelometers and velocimiters.

Stations can be easily and quickly deployed

Data can be transmitted in real time at INGV (UMTS. WiFi or satellite)

Data are stored in EIDA archive

• Portable seismic networks are deployed to improve the detection performance of permanent monitoring systems during seismic emergency or experiments

• The improvement in earthquake detection and location provide invaluable data for scientific studies related to hazard, tectonics and earthquake physics.

• Aftershocks or clusters of seismic events help in characterizing the geometry and dimensions of the causative faults.

• Knowing the number, size, and timing of aftershocks can help in foreseeing the characteristics of future seismic sequences in the same tectonic environment.

ITalian ACcelerometic Archive (ITACA)

ITACA 1.1 (1972-2011): 4800 three-component waveforms from ≈1000 earthquakes with M > 3 and ≈900 stations (almost entirely from the national accelerometric network RAN)

Soon version 2.0 will be released including data from 1972 to 2013 from all seismic networks operating in Italy

RINGRete Integrata Nazionale Gps

Geodetic GPS/GNSS Data (Global Positioning System/Global Navigation Satellite System), enable millimeter-scale surface motion measurements at discrete points

Permanent GPS/GNSS stations track both the slow interseismic deformation and the sudden elastic release by earthquakes

INGV promotes the development of new, high-quality GPS stations and the integration of existing GPS/GNSS networks (government and commercial)

~500 permanent GPS stations now provide an accurate image of the tectonic deformation in Italy

RING scientific goals are to understand:

- The forces that drive plate-boundary deformation

- The spatial distribution of tectonic deformation and earthquake occurrence in Italy

- How to reduce the hazards related to earthquakes
