Zusammenfassung:A seismic sensing unit includes four uniaxial sensors each capable of detecting a movement component along a respective axis having a respective orientation and arranged such that the angles between any two of said respective orientations of said respective axes are substantially equal, wherein the uniaxial sensors are arranged such that in use the respective axes are at substantially the same angle to the vertical direction and the horizontal direction, and wherein the uniaxial sensors are geophones, accelerometers, seismometers or their combinations.
