National Geophysical Networks in Latin America
Universidad de Chile, Santiago, Santiago, Chile


List of Attendees

The completion of the GRO-Chile project (joint IRIS/Univ. Chile installation of ten backbone geophysical observatories in Chile), the on-going expansion of the Chilean National Network, and the initiation of the earthquake reporting responsibilities of the Chilean Centro Sismológico Nacional (CSN) provides an opportunity to review this collaborative mode for national network development; its contributions to regional and global earthquake reporting and data sharing; its extension to other countries in the Americas; and applications in subduction zone research.

A workshop on National Geophysical Networks in Latin America: Best Practices, Challenges and Opportunities for Collaboration will review best practices in the planning, installation, operation, and maintenance of modern networks of geophysical instruments. Applications in both earthquake reporting and research will be discussed, along with opportunities for national, regional, and global collaboration and data sharing. Best practices for network planning and design, station deployment, instruments, communications, data management, and analytical tools will be described. Organization, management, staffing, and financial requirements will be discussed, with an emphasis on sustainable operations.

The development and structure of Chile's National Seismological Center (Centro Sismológico Nacional, CSN) will be used as an example. The USGS will describe applications in earthquake monitoring and reporting, with an emphasis on rapid W-phase analysis for moment determination and ShakeMap reporting on strong ground motions.

Conveners for the Workshop: Sergio Barrientos (Centro Sismológico Nacional de la Universidad de Chile), Susan Beck (University of Arizona), Anne Meltzer (Lehigh University), Gavin Hayes (USGS National Earthquake Information Center), Klaus Bataille (Universidad de Concepción)

Organizing Committee for the Workshop Program: Andy Frassetto, David Simpson (IRIS), Sebastián Riquelme (CSN), Gavin Hayes, Dave Wald (USGS NEIC)
