AB: The new National Seismic Network of Chile, sponsored by the Government and executed by the Departments of Geophysics and Civil Engineering of the University of Chile, will consist of 65 broadband stations, sampled at 50 sps, colocated with more than 200 strong ground motion sensors sampled at 200 sps as well as 140 GPS instruments sampled at 1 sps. These instruments will be deployed along the country (4200-km long) with near real time access. Satellite communications will be used for the BB and GPS devices directly linked to a central site in Santiago with a mirror system in a different site. The strong ground motion instruments will be accessed via phone lines. This network will be supported by the efforts of regional universities along the country that will run their own local seismic short-period arrays. It is expected that the three integrated networks will be installed during the next three years and be fully operational by the end of the period 2008-2010. The additional effort of installing regional networks is planned for a longer period.
