22 +* Bury seismometers at an appropriate depth for noise reduction and stable ground coupling, typically 0.5-0.8 metre depth.
23 23  * Orient the sensors correctly using a compass, paying special attention to the north direction. When using a compass to orient the sensors, ensure it is kept away from metal objects or structures that could interfere with its magnetic field. Accurately determine the north direction for precise sensor orientation.
24 +* Ensure the sensor is leveled correctly. A paver or concrete slab can be used to allow for more accurate leveling.
