ZAMG is involved in the EU INTERREG IIIA project “FASTLINK”, together with the Protezione Civile della Provincia autonoma di Bolzano (Italy) and the ETH of Zurigo (Swizerland). The commercial Antelope-software suite from BRTT (Boulder Real Time Technologies - www.brtt.com) has been chosen as the common basis for real time data exchange, rapid location of earthquakes and alerting. Each institute contributes to the seismological monitoring in the South-Eastern Alps by sharing data from its seismic network. Antelope is a powerful software suite that easily allows sharing data in real-time among several institutions by means of its module ‘orb2orb’. The current Antelope setup of all institutions involved in data acquisition, sharing and archiving is described, together with the future evolution of the project. The border region of Slovenia, Austria and NE Italy has experienced several destructive earthquakes in the past. Different seismic networks are operating in the area supporting monitoring, alerting and research. The example of recent strong earthquakes demonstrated that the integration of services provided by the neighboring networks is essential for a rapid and efficient intervention.

The triangles indicate the seismic stations and the black arrows indicate the redundant orb2orb connections among the seismological datacenters involved in the Interreg IIIa projects. Antelope @ OGS Antelope @ DiG (http://rtweb.units.it/) Starting from 2000 the DiG manages 2 duplicates Antelope installations, one at DiG headquarters in Trieste and the second one at the SOR (Emergency room of the PCFVG headquarters in Palmanova). Both system run on high-availability SUN workstations. Thank to the facility in adapting the system to the users needs, new real-time procedures have been developed, both for civil protection purposes (alert system: e-mail, sms, WEB, etc.) and for scientific research. In particular, a procedure for a fast automatic Mw computation and ground motion parameters (PGA, PGV, PSA03, PSA10, PSA30, Arias and Housner) extraction has been written using perl and fortran90 Antelope interfaces (Gallo et al. 2010). A regional calibration of real-time ShakeMaps has been also implemented (Moratto et al., 2009). New database tables developed at DiG. CRS procedures BRTTAntelope The Antelope software is also used to manage the DiG stations of the NE Italy Broadband Network and the accelerometric stations of the RAF*-RAN** integrated network (Costa et al., 2010) in Friuli Venezia Giulia, and to manage the relative accelerometric database. In addition to the connections with Interreg datacenters, DiG exchanges regional accelerometric data with the Antelope system running at the National Civil Protection headquarters in Rome and the ground motion parametric data with INGV in Rome. Antelope system is interfaced with SeisComP servers to exchange seismological data with INGV both in Trieste and Palmanova. *) Friuli Venezia Giulia Accelerometric Network (DiG) **) National Accelerometric Network (National Civil Protection Department (DPC), Rome, Italy). The Antelope-software suite is used at OGS - CRS as the main data acquisition tool by the Seismic Network run by OGS in Northeast Italy. The main OGS-CRS Antelope server is running in Udine on a 2 nodes SUN-Fire-V240 cluster: the main module takes care of data acquisition, automatic location determination, data archiving and exchange, plus the alert system via Short Message Service (SMS), email, fax and web. For Antelope users, real time data from the OGS Seismic Stations is available at address antelope.crs.inogs.it:51558. Another Linux workstation running Antelope (antelope-wks) at the OGS-CRS headquarters in Udine is used for post-processing including ShakeMaps and manual relocation determinations. Data is also forwarded for redundancy to a SUN-Fire-V245 Antelope machine (antogs) at Protezione Civile della Regione autonoma Friuli-Venezia Giulia (Civil Protection of the Friuli-Venezia Giulia region) headquarters in Palmanova and for convenience to a Linux Antelope machine (antelope-crsts) at OGS headquarters in Trieste. Data from the Antelope SUN-Fire-V240 cluster at OGS-CRS headquarters in Udine are also forwarded to the OGS-CRS seedlink server that runs underSeisComP on the same machine: this data is available on request. Earthquake detection and notification The integrated accelerometric RAN-RAF Network in the Friuli Venezia Giulia region. The Postojna stations is installed in collaboration with ARSO. Antelope @ ZAMG Antelope @ ARSO Records of seismic stations within 100km from the epicenter of the last damaging earthquake in Slovenia (2004/07/12 13:04 Ml 4.9, near border with Italy and Austria). Foreign stations are dimmed. All the data were available in real time. Seismic data exchange diagram. Network codes folow country names. Seedlink data are being imported in Antelope ORB in real time. Relevant waveforms are routinely being picked for better location determinations. In 2001 the Antelope software was adopted by Seismology and Geology Office at the Environmental Agency of the Republic of Slovenia for management of the new slovenian seismic network. Automatic real time earthquake solutions are used for quick alerting while thorough analisys is done by manually picking the seismograms with Antelope’s dbpick program and locating with Hypocenter (Lienert, 1994). There are automatic procedures implemented for earthquake alerting and for data quality control by email, sms and web. Automatic event determinations are made available to the public through web page http://www.arso.gov.si/potresi/obvestila%20o%20potresih/aip/index.html. Seismic data are being shared in real time with Orfeus data center, with all the neighbouring countries and several other countries in Europe. To improve data recovery, low-cost industrial computers are being installed at seismic stations, running SeisComP and sending data to Antelope powered backup data center which was set up recently. At the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Vienna the Antelope-software has been chosen 15 years ago as the main acquisition system for the National Seismological Service of Austria. Experience has shown, that the software can be easily adapted to local needs and allows easy control of data transmission processes and state-of-heath. Current developments involve the inclusion of a sophisticated crustal model to improve the location accuracy of seismic tremors on Austrian territory. The Antelope-software is also used in the EC-funded Project HAREIA, which also deals with installation of additional strong-motion stations in the partner regions of Tyrol, South Tyrol, Veneto and Friuli-Venezia Giulia. All stations will be monitored and the data are being processed by the Antelope-software.
