2 RESEÑA HISTORICA DE LA RSNC
INSTITUTO COLOMBIANO DE GEOLOGÍA Y MINERÍA INGEOMINAS Libertad y Orden República de Colombia RESEÑA HISTORICA DE LA RSNC The RSNC, arose from the need for a modern and reliable tool to provide accurate information regarding the seismicity of the country. Here are the most important dates in the development of the RSNC, since its creation: 1987: RSNC`s Preliminary activities are initiated . 1988 Colombian staff training in Canada. 1989 TELECOM cooperation to enable satellite links. 1990 infrastructure works are initiated for receiving and analyzing data. 1991 Installing the system for receiving satellite data and the acquisition and processing systems. 2

INSTITUTO COLOMBIANO DE GEOLOGÍA Y MINERÍA INGEOMINAS Libertad y Orden República de Colombia of the 14 planned stations were instaled 1994 Official Opening of RSNC with 15 stations in operation. 1995 The Central Government contributed with U.S. $ 1,000,000 to expand the coverage of seismic network with five more stations. 1997 The operation of these five stations and 50 accelerometers starts. 1998 El Rosal station became part of the International Monitoring System (IMS) of the CTBTO, whose main objective is to assist in the monitoring and detection of nuclear explosions. 2001 The Rosal station is updated to connect via satellite to headquarters of the CTBTO in Vienna. 3

INSTITUTO COLOMBIANO DE GEOLOGÍA Y MINERÍA INGEOMINAS Libertad y Orden República de Colombia : A process of updating and expanding of the Seismological and Volcanological System of Colombia is started, projected to the years The aim is to expand networks and broadband technology purchase. 2009 The RSNC has 34 stations installed, 13 broadband and 21 short period. It also has regional stations in subnets. Near future (2011 – 2012) To have 57 stations in operation, as follows: 42 Satellite stations: 23 BB 19 Short period 15 Short period stations in subnets 4
