AB: The seismic phenomenon is one of the most important natural hazards for Colombia (e.g. Armenia, 1999, M=6.1; Calima, 2004, M=6.7). In spite of big efforts implemented by different institutions in order to reduce the seismic vulnerability in Colombia, the understanding of the nature of the seismic phenomena and its spatial and temporal distribution and evolution is insufficient. In order to estimate the seismic hazard it is necessary to know the geological conditions of those regions where the cities are developing, it is necessary to study their structure, dynamics and behavior, looking for information which allows understand the processes which generate the seismic events and to obtain an adequate model of ruptures of the system. In this paper we show the implementation of an instrumental seismological network for the Colombia's capital city: Bogota. This project: "The Center-East Broadband Seismic Network" consists on fifteen seismological three components, broadband stations, located near the coordinates: 4.5 N latitude and 73.5 W longitude joined to a similar distribution of geodetic stations (GEORED). This network is expected to be a complementary, high sensitive addition to the National Seismological Network of Colombia. This network has to bring the possibility of improving the understanding of the seismic hazard in the Bogota's region, considering the better understanding of the spatial and temporal microseismic activity in this region, where live more than 15 millions people (30% of Colombia's population), and more than 40% of the GIP is concentrated. Based on the obtained information it will be possible to incorporate structural elements to the adequate development of this region considering the seismic hazard and supply the guidelines to designs and constructions.
