Data acquisition system for the study of earthquakes precursors by measuring magnetic field emissions

There are several evidence of magnetic field alterations that have been registered instants before seismic activity, in different parts of the world. Under the hypothesis that there is a relation between both phenomena, a multiple disciplinary project is being developed for verifying this statement. In this paper, a prototype for a data acquisition system is presented for obtaining valuable information in order to find this evidence. It's main objective is to sense and register electromagnetic variations as well as other relevant variables found in high seismical activity areas. This system is completed with several communication tecnologies, for remote monitoring of the information.
