EPOS- a multiparameter measuring system to earthquake research

The approach to earthquake prediction by geophysical, geochemical and hydrological data needs real time measuring equip- ment and modelling of statistical data. A progress in this field is presented in this paper by the developing of a new versatile measuring system EPOS (Earthquake Precursor Observation System) based on experiences and recent results from different re- search groups. EPOS is an innovative multiparameter station, which can continuously record as a function of time up to 17 geochemical and geophysical parameters suitable to earthquake research. A microcomputer system inside EPOS handles data exchange, data management and control and it is connected to a modular sensor system. The number of sensor modules can be selected according to the needs at the measuring site. Successful test results of EPOS station working for two years in Dos Arroyos, Mexico, at the Pacific ocean cost are presented.
