Abstract Orientation is very important for a seismometer, whether it is installed on surface or in borehole. Orientation relying on magnitism must have error if there is ferromagnetism around the seismometer. The method of coherence analysing by use of ground pulsation and event data by two seismometers is presented to develop the calculation model and operation method for seismeter’s orientation.
Key words :
correlation coefficient
ground pulsation
seismometer
rotation transformation
