Geodetic space techniques provide point coordinates and their velocities. It is necessary to register seismic events upon their occurence for a correct modelling of the point velocities. Seismometer are usually operated in regional or global networks in order to determine the epicenter and the seismic wave propagation.
TIGO operates a broadband seismometer with 6 channels. It is used in the seismic network of the Universidad de Concepción.
