Objective To develop, build and test the prototype of a compact broad bandmagnetotelluric/audiomagnetotelluric system with special characteristics designed forapplication in earthquake prediction research; subsequently to detect temporal changes ofmagnetotelluric parameters in the seismogenic zone of the crust by continuously monitoringthe natural electric and magnetic field variations in all three components, respectively. It isexpected to contribute to clarifying the relationship of observed anomalous variations to theoccurence of earthquakes, to earthquake activity patterns and to the local and regionaltectonic structure, in order to identify their importance for earthquake prediction.A compact broad band magnetotelluric/audiomagnetotelluric systemis to be developed, which includes online data analysis, andallows for continuous high data rate recording withoutmaintenance over a period of one month.Continuous recording in the field will be carried out in threeregions : Central Greece, the central Apennines in Italy, and theNorth Anatolian Fault Zone in north-west Turkey. Two types ofinstruments will be used. One type developed within EPOCH willbe run in all three areas in order to investigate unknownanomalies in the natural electric and magnetic field variationsat low frequencies down to DC. The other type will be a newdevelopment for earthquake prediction research in order to extendthe observable frequency range up to 1000 Hz, and in particularto investigate changes of the conductivity structure in the earthcrust as an indication for an earthquake preparation process. Itwill be applied in Greece and Turkey.Three prospection campaigns are planned for the above mentionedareas in order to study the local conductivity structure of theEarth's crust, and, thus, provide information necessary forselecting favourable sites for continuous recordings. Anadditional field campaign will be organised for testing andfurther developing a new technique of measuring the verticalcomponent of electric field variations.Data analysis and scientific interpretation includes theinversion of the magnetotelluric data of the prospectioncampaigns for studying the conductivity structure in the vicinityof the most favourable sites. It should also reach a definiteconclusion on the conditions under which the new"vertical-component-technique" can be introduced successfully.The analysis and interpretation of the continuous recordings inthe three different areas is supposed to detect possibleearthquake precursory phenomena, and will be based on amultiparameter approach that compares the results of broad bandmagnetotellurics with interdisciplinary data sets of other kind.
