    • Method and apparatus for carrying out seismic survey includes a plurality of spaced apart seismic detecting sensors each having a geophone unit for detecting seismic activities. The sensors are linked serially with a cable. One end of each geophone unit is flexibly linked to a carrier frame so that the geophone units pivotally move freely relative to the carrier frames. The cable passes through the carrier frames so that the carrier frames are spaced apart serially. Each geophone unit carries a vibrator, a plurality of geophones, a compass, and an inclinometer. The vibrator is positioned on the free end portion of the geophone unit, for embedding the geophone into the ground, while the compass is positioned farthest away from the vibrator. The free pivotal movement of the geophone units enables them to dig into the ground.
