Earthquake and volcanic eruption prediction: is the source of the mechanical-electrical transformation close to the hypocentre or in the vicinity of the monitoring site?

Obiettivo



This joint research project brings together five research institutes from the NIS and three west European universities. The main field of research is related to physics of the Earth: earthquake and volcanic eruption prediction. At the end of the three-year project a much better understanding of electromagnetic and seismic precursors will be gained and disseminated throughout the international community. This knowledge can then be used in order to select the best observation sites worldwide and to minimise the human consequences of earthquakes and volcanic eruptions.

To achieve this primary goal, research will be undertaken in four different fields: firstly the hardware development. A Russian prototype of a 10 channel seismoelectromagnetic recording station will have been built and tested in tectonically active regions (Kyrgyzstan, Turkmenistan, Ukraine, Greece and the French Alps). The specifications will be agreed upon by the participants and by external international organisations active in the field of earthquakes and volcanoes. It will be high performance, rugged, low consumption and low cost. It will then be available on the international market for anybody involved in earthquake and volcanic eruption prediction and for regional geophysical studies. An international network of such stations will tentatively be organised once the project is completed; secondly the software development. Two specific pieces of software will be developed and tested. The first concerns simultaneous processing of electromagnetic and seismic signals. The second concerns the analysis of records obtained simultaneously at numerous network stations. It is aimed at determining precisely the location of the source of each signal such as electromagnetic and seismic; thirdly the data collection. Data will be collected in Turkmenistan, Ukraine, Greece and France after the units have been successfully tested in Kyrgyzstan; and finally the data interpretation. The data collected will be interpreted together with external data obtained in other regions by the scientific community for the same purposes.

Results are expected in: selection of electric, magnetic and seismic sensors to be used in extreme environments; design, manufacturing and testing of a 10 channel acquisition unit; design, development, implementation and testing of software for processing and interpretation of electromagnetic and seismic precursors; several months of continuous recording of the natural electromagnetic and seismic activity in Kyrgyzstan, Turkmenistan, Ukraine, Greece and France with the newly developed systems; integration of this recording data with sets of other institutions; international marketing for the acquisition and processing units; proposal for the establishment of international networks with similar equipment and software; participation in workshops, seminars and conventions related to earthquake predictions; and publications in international journals.
