Emphasis will be placed on the development of methodology suitable for the extended monitoring of gas composition on-site, supported by laboratory determinations to validate the field data where necessary.
Monitoring of local climatic conditions and seismic activity will be necessary, as well as investigation of other parameters with the potential to affect gas composition, such as the effects of Earth Tides.
Finally, permanent base stations will be established, in order to have continuous and real time monitoring, storage, and transmission via satellite of the field data to scientific centers for subsequent automatic processing and indication of alert thresholds.
This proposal is related to one of the most important geophysical problems related to the estimation and prognosis of a seismic event. The solution of this geophysical problem is connected to the evaluation of the whole line of economical and social problems of people living in seismic active regions.
The tensional properties of the earth's crust, which are showing up at large intervals, will be recorded and encountered by means of sophisticated geophysical methods and equipment.
Gases emanating from soils above fault zones in seismically-active areas contain the principal atmospheric gases nitrogen and oxygen, accompanied by varying amounts of carbon dioxide, radon, thoron, helium, argon, hydrogen, and methane. The main part of this gas mixture is generally considered to emanate from degassing sources at relatively shallow depth, but deeper-seated provenances are thought to be responsible for much of the helium, methane and hydrogen. The underlying reasons for the apparent surface variation in gas composition are not wholly understood, and it is therefore proposed to collect soil-gas data over long periods at one or more recognized seismically-active localities in Greece, Russia, Armenia, and Albania, as a preliminary to establishing a capability for earthquake prediction based on variations in soil gas composition.
Information obtained from these surveys will be compared with data from on-going parallel studies in Greece where all data will be collected via satellite in real time.
