It is
the first time a combination of geophysical methods is used and some results
have been obtained during the geological hazard investigation in Ia Băng and Ja
Ve areas,
The
methods of seismic refraction and methods of electrical sounding have been used
to define the existence of faults under basalt layer, with breakdowns, block
glide and character of geophysical parameters, such as the speed of elastic wave
transmission (v), deformation mođule
The
methods of mercury, alpha particle activity, rađon measurement and observation
measurement during two seasons of the year have been used to forecast the
present situation of
faults and to classify them according to their activities.
