| Research Abstract |
Geophysical and geological surveys at several VAN stations in Greece were carried out to reveal characteristic subsurface features in those areas. The purpose of the present studies were to discriminate geological and geophysical contrast between sensitive and insensitive VAN stations.
In Assoiros region, one of the sensitive stations in northern part of Greece, we measured gravity, magnetotelluri, and electrical resistivity. After calculations, we obtained gravity anomaly distribution map and resistivity structures around the Assiros VAN station. The gravity anomaly distribution revealed that the Assiros station does not situate on geological active structures, such as active faults or recent dykes.
At Ioannina VAN station, the most sensitive station in northwestern part of Greece, new data concerning electric resistivity of near surface were obtained. Magnetotelluric data were also added in this area.
At Pirgos area, we added several gravity data.
In order to compare geological conditions of VAN stations more efficiently, geological and geomorphological observations were carried out at several VAN stations (Keratea, Bolos, Assiros, Ioannina, Patras, Pirgos, Sparta, Lutraki) all over Greece. Taking geophysical observations at some VAN stations into consideration, geological condition on VAN stations to be sensitive may related to ground water level around the station.
More geological and geophysical comparisons are required to establish criteria to select sensitive stations of geoelectrical current for earthquake prediction.
