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 didnt 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.
