Abstract
Abstract A satellite-based seismic network with 13 sites has been installed in Colombia. Each site has one vertical short-period seismometer. The purpose of the network is 2-fold and complementary: a number of the sites are on or near active volcanoes in order to give warnings in case of recurring volcanic activity, and all the stations will create the foundation of a national Colombian Seismic Network. The satellite links have room to accommodate a future expansion to 24 sites. All the data are sent continuously to Bogota by satellite, for analysis. To aid in the volcano monitoring, a visual record is produced for each site. In addition, continuous data or optionally triggered events are stored on disks. An associated analysis system determines epicentral parameters for the earthquakes that are occurring in Colombia and then produces earthquake catalogs.
