RSBR: The Brazilian Seismic Network
Efforts from four different institutions are establishing the new permanent Brazilian Seismographic Network (RSBR) that today is composed of 82 broadband stations operating across different regions in Brazil: University of São Paulo (USP) operates 24 stations, University of Brasília (UnB) 26, National Observatory (ON) and Rio Grande do Norte Federal University (UFRN) 16 each. USP and UnB stations form a sub-network called BRASIS (BL and BR network codes respectively), ON stations form the RSIS sub-network (ON) and UFRN the RSISNE sub- network (NB). Most stations transmit in real-time via satellite or cell-phone links. The data/services distribution topology is based in technology and concepts adopted by the EIDA network in Europe. Each institution maintains a local data center with a SeedLink/ArcLink servers that can be used to obtain real-time and archived waveform data when allowed by each participant. All nodes use the SeisComP3 system as a levering back-end.
While the main RSBR purpose is to monitor the seismicity in Brazil, its geometry and position in relation to the majority of the South America seismogenic sources will enhance the data availability in the distance range 5° to 35°, filling a gap in the previous station distribution in South America.
