2.1 | 10 | == **Site selection and preparation** == |
| |
1.1 | 11 | |
| |
3.1 | 12 | * ((( |
| 13 | Choose a location with minimal noise interference and away from urban areas, traffic, and industrial activities. | ||
| 14 | ))) | ||
| |
2.1 | 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, leveling the ground | ||
| |
1.1 | 19 | |
| |
3.1 | 20 | == **Installing seismic sensors** == |
| |
1.1 | 21 | |
| |
3.1 | 22 | * Bury seismometers at an appropriate depth for noise reduction and stable ground coupling. |
| 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. | ||

1.1 | 24 | |
| |
4.1 | 25 | == **Setting up data**: == |
| |
1.1 | 26 | |
| |
3.1 | 27 | * Install data loggers or recorders compatible with the sensors. |
| 28 | * Ensure adequate storage capacity and configuration for the desired sampling rate and data format. | ||
| |
4.1 | 29 | * Establish a reliable power source, such as solar panels, batteries, or local grid connection. Use a compass to align solar panels facing north in the south hemisphere for optimal sunlight exposure. |
| |
6.1 | 30 | * Set up a GPS antenna to provide accurate time synchronization for the seismic data |
| 31 | * Ensure the GPS antenna has a clear view of the sky for optimal signal reception. | ||
| |
4.1 | 32 | * Calibrate sensors and data acquisition systems for accuracy. |
| 33 | * Test for sensitivity, noise levels, and overall performance. | ||
| |
1.1 | 34 | |
| |
5.2 | 35 | == **Fire safety measures and documentation in seismic station installation** == |
| |
1.1 | 36 | |
| |
4.1 | 37 | * In bushfire-prone areas, clear a wide perimeter around the installation to reduce fire risk. |
| 38 | * Use fireproof blankets to cover equipment, providing an additional layer of protection against fire damage. | ||
| |
5.2 | 39 | * Install a metal net over the entire setup to shield it from external elements |
| |
4.1 | 40 | |
| 41 | * Document the installation process, including sensor types, orientations, locations, and system configurations, along with fire safety measures implemented. | ||
| 42 | * Record essential metadata for seismic data interpretation. | ||

6.3 | 56 | * **Logbook Maintenance**: Document essential details: |
| 57 | ** Station name, latitude/longitude, team members, date/time. | ||
| 58 | ** Serial number (SN) of sensor, site notes. | ||
| 59 | * **Node Placement**: Use biodegradable plastic bags for node protection. | ||
| 60 | * **Orientation and Site Description**: | ||
| 61 | ** Compass measurements (adjust for inclination). | ||
| 62 | ** Detailed description of the site, including landmarks. | ||
| 63 | * **Visibility and GPS Marking**: | ||
| 64 | ** Use distinctively colored flags for easy location. | ||
| 65 | ** Mark location with GPS; record in logbook and device. | ||
| 66 | * **Photo Documentation**: Take multiple photos from various angles. | ||
