  2. Pre-deployment Equipment QA • QA all of your equipment in a controlled, lab environment prior to deployment. • Test your recording parameters in the lab. • Know your equipment: • Be familiar with your installation plan. • Practice setting up a station in the lab and in a simulated field environment.

  3. Prepare • Develop deployment and servicing sheets. • Know the metadata you will require before you are in the field. • A well stocked tool box is a must. • Think spares, especially small items that can be misplaced. • Identify and collect the construction materials you will need for your seismic station.

  4. Site Selection • Far from human-generated noise (roads and machinery) • In a temperature-stable environment • Far from the ocean • On solid (competent) rock • Sky view • Good Drainage • Secure

  5. Vault & Site Construction • Provide sensor coupling to Earth • Protect the instruments: • Flooding • Temperature fluctuations • Animals • Secure

  6. Field Practices • Take comprehensive field notes. • If it is not documented, it didn’t happen • Take your time. • Make sure you will record useful data. The “Fort Five” • Do you have power? • Does the seismometer produce signal? • Is your instrument programmed correctly? • Do you have timing? • Is your data being telemetered or stored on-site?

  7. Monitor Your Site & Data • Monitor your sensor outputs before you close the vault and/or leave the site. • Do a service run within 2 weeks of the initial deployment. • Monitor your state-of-health channels. • Look at waveforms.
