Managing Waveform Data and Related Metadata for Seismic Networks

Kuala Lumpur, Malaysia

2007-10-21 — 2007-10-26

Background Information

Background

The past twenty years have seen a revolutionary growth in the way we monitor seismic hazard: analog seismographs were replaced by digital instruments that are sensitive over a wide frequency band; the digitization made it possible to group instruments in local, often telemetered networks with centralized archiving of digital waveform data.

Earth does not know about national borders, and seismologists have spearheaded efforts to share their data. The growth of the Internet has made it possible, in principle, to link data centers all over the world. In fact, for some networks, such linkages have already been established, and a mature system of data management has grown in such large data centers as ORFEUS (Europe), JAMSTEC (Japan) and IRIS/DMC (US).

Scope

This workshop is a major attempt to disseminate the experience and expertise in seismological data management. It is directed at managers and operators of seismic networks. We shall provide training in the application of advanced database management systems, educate participants on the scientific developments that form the basis of modern seismometry, and give a short introduction to modern methods of analysis possible with the current advanced instrumentation and databases. We expect participants to come away from the workshop with all the necessary knowledge to set up and maintain their own database and to link their network to the growing global network for data access.

Network managers are encouraged to make a brief presentation on their network.

Participation

In order to keep the workshop efficient, we will only admit a limited number of participants. As we expect a wide interest, the organizers will make a selection of the applicants from the preliminary registrations. In this selection, we will mainly consider seismic network operators or prospective network operators and, if necessary, avoid multiple participation from one institute. We intend to inform each person that has sent a preliminary registration as soon as possible on the possibility to participate.

The focus of this workshop will be networks from the Southeast Asia. Priority will be given to applications from seismic network operators from this geographical area.

Financial Support

There will be no registration fee. Further, financial support is available from IRIS and the workshop co-sponsors.

Registration

Registration opens May 1 and closes June 30, 2007. Selection notices will be sent out by July 15, 2007.
