Sustainable Networks: The Next Challenge in International Earthquake Monitoring

The first 20% of the full text of this article appears below.

Is there a "right" model for global, regional and local earthquake monitoring? It's timely to ask that question because of a convergence of events and trends: the 2004 tsunami and the calls for enhanced early warning systems based on national and regional seismological networks, the growingstrength of a private sector marketing turn-key solutions for regional and local earthquake monitoring, the capitalization of these systems by nations with assistance from international development organizations, and the continuing and growing recognition that knowledge of seismicity and ground motions, and their geographic relationship to human assets, are essential components of earthquake risk management. This has resulted in the procurement and deployment of national networks and the expansion of global networks into critical underserved regions at an almost unprecedented rate. Additionally, the relative ease with which portable arrays can be deployed over interesting geological targets has engendered the current era of experimental seismology and has given seismologists a scientific and technical platform supporting international research and education collaborations. When these are combined with the existing "permanent" global and regional network deployments, the amount of broadband information being collected is staggering.

Domenico Giardini, who until recently led the Federation of Digital Seismological Networks (FDSN), gave a presentation at the last Incorporated Research Institutions for Seismology (IRIS) workshop that . . . [Full Text of this Article]
