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.

República de Colombia• 1993 13 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.

República de Colombia• 2005-2006: A process of updating and expanding of the Seismological and Volcanological System of Colombia is started, projected to the years 2011-2011. 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
