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.
prepare
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.

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
vault site construction
Vault & Site Construction
  • Provide sensor coupling to Earth
  • Protect the instruments:
    • Flooding
    • Temperature fluctuations
    • Animals
  • Secure
field practices
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?
monitor your site data
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.
