8 +* If possible, choose a location with minimal noise interference and as far away from traffic and people as possible. Try to keep your station out of site to avoid theft or tampering. The site should not be installed in a place where people would ever stumble upon it (e.g. a walking trail or public area).
9 +* Nearby Trees, bushes, power poles etc can induce low period noise in your data when they sway in the wind. A rule of thumb is to have your sensor at least as far away from these as their height.
10 +* Cattle and stock can and will destroy your site. NEVER EVER install a station where cows can get to it.
11 +* If the area looks like a place that has flooded, or may flood again, absolutely assume that it will. This very much includes dry riverbeds or ponds. Always prefer locally elevated terranes.
12 +* The harder the soil, the better the signal. Sand and mud are your enemy.

15 -* The site should be geologically stable and representative of the area's seismic characteristics.
16 -* Accessibility and security of the site are also important factors.
17 -* Conduct a detailed survey of the site, including topographical, geological, and geophysical assessments.
18 -* Prepare the site by clearing vegetation and levelling the ground.

19 +* Bury seismometers at an appropriate depth for noise reduction and stable ground coupling, typically 0.5-0.8 metre depth but deeper the better.
20 +* Ensure the sensor is leveled correctly, typically the sensor can be placed on a well leveled paver to make this easier.
24 24  * Orient the sensor correctly using a compass, paying special attention to the north direction and accounting for declination.
25 25  ** 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.
23 +** It is recommended to take a picture of the sensor's orientation next to the compass.
26 26  * It is recommended that the following sensors be installed with a PVC tube covering to prevent corrosion and other environmental degradation:
