ORFEUS Working Group 2: Instrumentation Workshop in Rome (Italy), November 2000

Damiano Pesaresi
ORFEUS Working Group 2 Chairman

At the end of November 2000 ORFEUS held in cooperation with Istituto Nazionale di Geofisica (ING) a workshop "Installation and operation of seismic broad-band stations". About 40 participants came from all over the world.

The program covered various issues related to running a modern broad-band seismic station: we started from the installation of digital feedback seismometers, continued with transfer functions, system responses, calibration. We touched then the issues of various means and formats of data archiving and dissemination. We gave also an overlook of data telemetry.

Teachers were selected from the experts in the relative seismological fields, and they made use of real seismic instrumentation made available by ING and workstations by SUN Italy.

The Workshop was organized in conjunction with the First European Antelope Users Group meeting and the Second European Quanterra Users Group meeting. This stressed once more the close collaboaration between ORFEUS and various entities of the global seismological community, including for example IRIS.

I have to thank, among the others, the ING President Prof. Boschi and Tiziana Lanza and Alessandra Paparelli who helped a lot with local organization.

The ORFEUS Instrumentation Workshop 2000 followed the guidelines seth forth by the experience of the ORFEUS Instrumentation Workshop 1998: it was organized succesfuly in Prague in November 1998. It was then the first time that the annual meeting of the Quanterra Users Group (group of seismic network operators that use high-resolution seismic data acquisition systems produced by Quanterra) was held in Europe.

In the future we are considering having the ORFEUS Instrumentation Workshop every two years, maybe again in conjuction with the Quanterra Users Group meeting. We are also considering to include more exercises, both theoretical and practical, and more data handling lessons. After all, with a good coverage of the European territory with broad band digital seismic stations, the new developments in modern seismology are focused in data telemetry and exchange, which involves data archiving, conversion, propagation and handling.

We would appreciate suggestions from ORFEUS participants on the content of future similar workshops and therefore, please, do not hesitate to contact us.
